The Metallicity and Distance of Leo A from Blue Supergiants
Published 2023-01-01“…We explain the bulk of this discrepancy with blue loop stellar evolution at very low metallicity and show that the combination of metallicity effects and blue loop evolution amounts, in the case of Leo A, to an ∼0.35 mag offset of the FGLR to fainter bolometric luminosities. …”

A Revisit of the Mass–Metallicity Trends in Transiting Exoplanets
Published 2024-01-01“…The two prevailing planet formation scenarios, core accretion and disk instability, predict distinct planetary mass–metallicity relations. Yet, the detection of this trend remains challenging due to inadequate data on planet atmosphere abundance and inhomogeneities in both planet and host stellar abundance measurements. …”

The Metallicity–Electron Temperature Relationship in H ii Regions
Published 2024-01-01“…In LTE, radio recombination line (RRL) emission and free–free continuum emission are accurate extinction-free tracers of the H ii region electron temperature. Since metals act as coolants in H ii regions via the emission of collisionally excited lines, the electron temperature is a proxy for metallicity. …”

Stellar Neutrino Emission across the Mass–Metallicity Plane
Published 2023-01-01“…Overall, across the mass spectrum, we find metal-poor stellar models tend to have denser, hotter, and more massive cores with lower envelope opacities, larger surface luminosities, and larger effective temperatures than their metal-rich counterparts. …”
