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…

JWST Exoplanetary Worlds and Elemental Survey (JEWELS) II: Condensation Temperature Trends and Galactic Chemical Evolution in JWST Planet-Hosting Stars

Qinghui Sun, Xianyu Tan, Gordon +5

We present high-precision chemical abundances for 25 FGK-type stars hosting exoplanets observed in JWST Cycle 3 programs and all GTO and DDT programs from Cycles 1-3, based on high…

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…
