[astro-ph.SR] Recent observational studies have suggested that the Sun may be chemically peculiar relative to the majority of solar twins.
![Elemental [X/Fe] abundances derived in this work as a function of stellar age. The solid orange lines show the best-fit linear age–abundance relations derived in this work, and the dotted grey lines show the corresponding relations from M. Bedell et al. (2018) for comparison. -- [astro-ph.SR]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/The-Sun.png?resize=1200%2C718&ssl=1)
