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…
The Sun's chemical peculiarity: disentangling Galactic chemical evolution and planetary engulfment in solar twins
Mia Babatsikos, Fan Liu, Amanda Karakas +5
Recent observational studies have suggested that the Sun may be chemically peculiar relative to the majority of solar twins. Here, we re-analyse high-resolution, high signal-to-noi…
Planet engulfment in the chemically anomalous HD 129171/HD 129209 pair
Anne Rathsam, Jorge Meléndez, Rodolfo Smiljanic +2
Binary systems composed of stars with similar parameters should have identical chemical composition. However, many chemically anomalous pairs have been found in the literature, suc…
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…
