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

Fan Liu, Gordon (Kai Hou) Yip, Qinghui Sun, Sharon Xuesong Wang, Xianyu Tan, Zhengduo Li, Zitao Lin

Condensation temperature trends in 25 planet-hosting stars show no dependence on stellar or planetary properties after galactic chemical evolution correction.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The Tcond slopes show no dependence on stellar or planetary properties, indicating that they reflect a mixture of multiple mechanisms, with planet-related signatures entangled in GCE and stellar evolution effects. Thus, Tcond trends require careful interpretation.

C2weakest assumption

That the strictly differential line-by-line analysis relative to the Sun combined with isochrone ages yields abundances and ages accurate enough to reliably detect or exclude dependencies on planetary properties in a sample of only 25 stars spanning a range of metallicities and temperatures.

C3one line summary

Condensation temperature trends in JWST planet-host stars are independent of stellar and planetary properties after GCE correction, indicating mixed origins from galactic evolution and stellar processes.
