The Sun's Golden Core: Exploring Solar Aromatics

The sun is a metal-rich type I star, with about 2% of its atoms being elements other than hydrogen or helium. The sun's mass is 2.0 x 10^30 kg, and about 0.0000000006 of this mass is made up of gold atoms. This equates to a mass of 1.2 x 10^21 kg of gold, which is roughly the same mass as one of the largest asteroids, Ceres.

The sun's gold was not created by the sun itself, as it is not large enough to go supernova. Instead, the gold in the sun was present when the sun was formed and came from older generations of supernovae.

The sun's gold comes from other stars

Gold is a chemical element with the atomic number 79. It is a precious metal that has been used for coinage, jewelry, and other works of art throughout recorded history. Gold is also used in electronics due to its high conductivity and resistance to corrosion.

The sun does contain gold atoms. During a total solar eclipse in 1868, astronomers detected helium, carbon, nitrogen, iron, and all the heavier elements of the periodic table—including gold—in the Sun's atmosphere. It is estimated that the sun contains almost 2.5 trillion tons of gold.

However, the sun is not massive enough to create gold through fusion. Gold is heavier than iron, which has an atomic number of 26. Any star that attempts to fuse iron will go into a supernova phase. It is only during this supernova phase that gold and other heavy elements are created, and only in the brief moments while the star is tearing itself apart.

So, where does the sun's gold come from? The answer lies in the fact that, except for hydrogen and helium, every atom in the sun and on Earth was synthesized in other stars. Gold is thought to have been produced in supernova nucleosynthesis and from the collision of neutron stars. In 2017, the spectroscopic signatures of heavy elements, including gold, were observed by electromagnetic observatories in the GW170817 neutron star merger event. This single neutron star merger event generated between 3 and 13 Earth masses of gold.

Therefore, the gold found in the sun and on Earth can be traced back to other stars that went supernova or collided with other neutron stars.

The sun cannot create gold through element synthesis

Gold is a chemical element with the atomic number 79. It is a dense, soft, malleable, and ductile metal that is highly valued due to its rarity. While it is possible to create gold through element synthesis, the process is complex, expensive, and not commercially viable.

The sun is not capable of creating gold through element synthesis. This is because the synthesis of gold requires specific conditions that involve extreme astrophysical events, such as stellar explosions, the collision of neutron stars, or certain black holes with orbiting matter accumulations known as accretion disks. These events provide the necessary conditions for the rapid neutron-capture process (r-process), which is essential for the formation of heavy elements like gold.

The sun, being a star, undergoes nuclear fusion in its core, where atoms combine to form other atoms. However, it is important to note that the sun does not have the required mass to undergo a supernova phase, which is necessary for the creation of gold. Only stars massive enough to go supernova can produce gold during their brief and violent death throes.

Additionally, the process of creating gold through element synthesis is technically challenging and energy-intensive. It involves nuclear reactions that require specialized equipment, such as particle accelerators, nuclear reactors, and sophisticated cooling mechanisms. The cost of creating gold artificially far outweighs its market value, making it economically unfeasible.

Furthermore, the gold created through these synthetic processes is often radioactive and hazardous to humans. It undergoes radioactive decay, transforming into a different element within a few days. The process of decontaminating the resulting gold is complex and costly, further diminishing the feasibility of synthetic gold production.

In summary, the sun is incapable of creating gold through element synthesis due to its insufficient mass and the absence of extreme astrophysical conditions necessary for gold formation. The synthetic production of gold is a complex, expensive, and hazardous process that is not commercially viable. Therefore, the sun cannot create gold through element synthesis, and any gold present in the sun was synthesized elsewhere.

The sun contains 100 quintillion 1 sextillion tons of gold

Gold has long been considered a precious metal, valued for its beauty, spiritual significance, and material wealth. It is also known as the "Metal of the Sun," with a deep connection to solar deities in ancient times. This connection is not just symbolic, as careful analysis of the Sun's spectrum has revealed that gold is indeed present in our star.

The Sun, with its massive size and weight, is composed of various elements, and among them, gold accounts for a minuscule fraction. Through spectral analysis, scientists have determined that about 6 ten-billionths (0.0000000006) of the Sun's mass consists of gold atoms. While this percentage may seem negligible, it translates to an astonishing quantity of gold due to the Sun's enormous size.

To put it into perspective, the Sun's mass is estimated to be 2.0 x 10^30 kg. That's an incredible 2,000,000,000,000,000,000,000,000,000,000,000 kg! Now, if we consider that 6 ten-billionths of the Sun's atoms are gold, we arrive at a staggering amount of the precious metal. This minuscule fraction of the Sun's mass equates to 1.2 x 10^21 kg of gold.

To visualize what this means, imagine an asteroid made of pure gold, measuring 913 kilometers in diameter, floating in the vastness of space. This massive asteroid, a fantasy come true for gold enthusiasts, would weigh approximately the same as the amount of gold in our Sun. In terms of value, this quantity of gold is worth an almost incomprehensible amount. At approximately £7 per gram, the gold in the Sun would be worth £7,900,000,000,000,000,000,000,000,000,000,000 pounds!

The presence of gold in the Sun is a testament to the incredible processes that occur within stars. Gold is formed in the interior of massive stars, and when these stars reach the end of their lives and explode as supernovae, the gold they contain is dispersed into the cosmos. This is how our Sun, billions of years ago, accumulated tiny amounts of gold from previous generations of extinct stars. So, while the Sun may not be a solid mass of gold, it undoubtedly contains an extraordinary amount of this precious metal, contributing to its brilliance and our fascination with it.

The sun is a metal-rich type I star

In astronomy, "metal-rich" is a term used to describe stars with a relatively high abundance of elements that are heavier than hydrogen and helium. This definition is distinct from the conventional chemical definition of a metal as an electrically conducting solid. The sun is categorised as a metal-rich type I star, which means it has a relatively high metallicity compared to older stars.

Metals in stars come from previous generations of stars that went supernova. The more metal in a star, the more generations of stars came before it. The presence of metals in a star means that the star was formed from the nebula of a previous star that died. Therefore, the sun's metal-rich composition indicates that it was formed from the remains of previous generations of stars.

The metallicity of a star is calculated using several methods, including determining the fraction of mass attributed to gas versus metals, or measuring the ratios of the number of atoms of different elements compared to the ratios found in the sun. The overall stellar metallicity is often defined using the total hydrogen content or the iron content of the star, as iron can be used as a chronological indicator of nucleosynthesis.

The metallicity of a star is important in understanding its age and composition. By definition, each population group of stars shows a trend where decreasing metal content indicates increasing age. The first stars in the universe, which had very low metal content, were deemed population III, followed by population II (old stars with low metallicity), and then population I (recent stars with high metallicity). The sun is considered a population I star, with a relatively high metallicity of 1.4%.

Observation of stellar spectra has revealed that stars older than the sun have fewer heavy elements. This suggests that metallicity has evolved through the generations of stars by the process of stellar nucleosynthesis. As older stars died, they returned metal-enriched material to the interstellar medium, enriching the nebulae from which newer stars formed. These younger stars, including the sun, now have the highest metal content.

In summary, the sun is a metal-rich type I star, indicating that it has a relatively high abundance of elements heavier than hydrogen and helium. This composition is due to previous generations of stars that went supernova, returning metal-enriched material to the interstellar medium and contributing to the formation of newer stars like the sun.

The sun's gold is in a gaseous state

Gold is created in the interior of massive stars. When these stars reach the end of their lives, they often explode and produce a supernova. During these giant explosions, elements with a high atomic number are formed, and this is where gold originates.

Billions of years ago, when our star, the Sun, formed, the cloud of gas and dust that condensed contained tiny amounts of gold and other heavy elements from previous generations of extinct stars. While it may not seem like much, about 6 ten-billionths (0.0000000006) of the Sun's mass consists of atoms of gold. However, because the Sun is so massive, this equates to a substantial quantity of gold.

To put it into perspective, the Sun's mass is 2.0 x 10^30 kg. In contrast, if 6 ten-billionths of the Sun's atoms are gold, that gives a mass of 1.2 x 10^21 kg (1,200,000,000,000,000,000,000 kg). This is approximately the same mass as one of the largest asteroids, Ceres, which has a diameter of 913 kilometers.

Gold, in its pure form, is not manufactured but rather occurs naturally in an elemental form. It has long been associated with the Sun and was considered sacred to solar deities in ancient times. Gold was believed to be the spirit of the Sun manifested on Earth and was often crafted into religious artifacts and images of the gods.

Therefore, the Sun's gold, like all gold, is indeed in a gaseous state in its natural form. This gaseous state is a result of the extreme temperatures and conditions within the Sun, which cause the gold atoms to exist in an energized, vaporous form.
