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…

Stellar population astrophysics (SPA) with the TNG. The Phosphorus abundance on the young side of MilkyWay

Mingjie Jian, Xiaoting Fu, Valentina D'Orazi +11

We present phosphorus abundance measurements for a total of 102 giant stars, including 82 stars in 24 open clusters and 20 Cepheids, based on high-resolution near-infrared spectra…

Lithium abundance in lower red giant branch stars of Omega Centauri

A. Mucciarelli, M. Salaris, L. Monaco +3

We present Li, Na, Al and Fe abundances of 199 lower red giant branch stars members of the stellar system Omega Centauri, using high-resolution spectra acquired with FLAMES at the…

The Gaia -ESO Survey: Lithium enrichment histories of the Galactic thick and thin disc

Xiaoting. Fu, D. Romano, A. Bragaglia +32

Lithium abundance in most of the warm metal-poor main sequence stars shows a constant plateau (A(Li)~2.2 dex) and then the upper envelope of the lithium vs. metallicity distributio…
