Title：The Solar Composition: Is the solar system unusual?

Abstract:
Solar composition is an important reference in astrophysics.
There are two main methods for determining this: using meteorites and using spectra from photospheres.
While the method using meteorites can determine the exact composition, it cannot be used for volatile elements. We can use spectrum to determine the abundance of volatile elements.
Recent advances in atmospheric modeling (3D Non-LTE) have updated the solar composition. However, the composition decision is still not perfect and has problems.
In this talk, I will review studies of solar composition and discuss whether the Sun is an ordinary star or not in terms of chemical composition.
