Transients and Stellar Activity as Revealed by Ultraviolet Diagnostic Tracers
Richard de Grijs, Martin A. Barstow, Deepak Chahal +5
Ultraviolet (UV) observations offer unique insights into transient and variable astrophysical phenomena, from the Sun and nearby stars to supernovae and star-forming galaxies. Here…
Limited imprint of high-mass IMF variations on sodium abundances in main-sequence galaxies
Ziyi Guo, Donatella Romano, Zhiqiang Yan +10
Growing evidence suggests that the stellar initial mass function (IMF) varies systematically across galaxies, deviating from the canonical Milky Way form. Such variations would mod…
Revisiting Ca II Activity Indices in FGK Stars: Systematic Biases in Infrared Triplet Measurements
Xiaozhen Yang, Xiaoting Fu, Mingjie Jian +10
Synthetic-template subtraction is widely used to measure chromospheric activity in large spectroscopic surveys. However, many solar-like FGK stars show systematically negative Ca I…
