    High-z Stellar Masses Can Be Recovered Robustly with JWST Photometry by R. K. Cochrane, H. Katz, R. Begley, C. C. Hayward, P. N. Best

    Published 2025-01-01
    “…These systematic trends, which exist for all star formation history parameterizations tested, have a tilting effect on the inferred stellar mass function, with the number densities of massive galaxies underestimated (particularly at the lowest redshifts studied) and the number densities of lower-mass galaxies typically overestimated. …”

    Are Stars Really Ingesting Their Planets? Examining an Alternative Explanation by Nadine H. Soliman, Philip F. Hopkins

    Published 2025-01-01
    “…Our results show that the distribution of refractory abundance variations (Δ[X/H]) has extended tails, with about 10%–30% of all stars displaying variations around ∼0.1 dex. These variations are comparable to the accretion of 2–5 M _⊕ of planetary material into the convective zones of Sun-like stars. …”
