Planets Around Solar Twins/Analogs (PASTA) III: Chemical Clock Relations in Planet-Hosting Solar Analogs
Qinghui Sun, Serat M. Saad, Yuan-Sen Ting +10
Context. Abundance ratios between elements synthesized on different nucleosynthetic timescales provide empirical chemical clocks for estimating stellar ages, but robust calibration…
A Bayesian Search for Planet Engulfment Signatures in Solar Analogs
Zimo Cheng, Sharon Xuesong Wang, Fan Liu +11
We present a systematic Bayesian search for chemical fingerprints of planet engulfment in 113 solar twins and analogs with high-precision abundance measurements, 45 of which host k…
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…
C3PO IV: co-natal stars depleted in refractories are magnetically more active -- possible imprints of planets
Jie Yu, Yuan-Sen Ting, Luca Casagrande +14
Chemical abundance anomalies in twin stars have recently been considered tell-tale signs of interactions between stars and planets. While such signals are prevalent, their nature r…
C3PO III: On the Lithium Signatures Following Planet Engulfment by Stars
Qinghui Sun, Yuan-Sen Ting, Fan Liu +8
Planet engulfment has been identified as one of the mechanisms for enhancing lithium abundance in stars. However, comprehensive investigations into lithium signatures following suc…
