Planets Around Solar Twins/Analogs (PASTA) II: chemical abundances, systematic offsets, and clues to planet formation
Qinghui Sun, Chenyang Ji, Sharon Xuesong Wang +5
Context. Previous studies have suggested that the Sun is relatively depleted in refractory elements compared to other solar twins or analogs, potentially as a result of planet form…

The Impact of Fiber Cross Contamination on Radial Velocity Precision
Chenyang Ji, Sharon Xuesong Wang, Kai Zhang +1
High-resolution spectrographs with precise radial velocity (PRV) capabilities require careful considerations in instrumental design and data processing in order to reach the 10 cm/…

Planets Around Solar Twins/Analogs (PASTA) I.: High precision stellar chemical abundance for 17 planet-hosting stars and the condensation temperature trend
Qinghui Sun, Sharon Xuesong Wang, Tianjun Gan +30
The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, hi…
