Spectroscopy of LMC Cluster Stars

Solar and Stellar Astrophysics 2020-03-18 v1 Astrophysics of Galaxies

Abstract

High resolution spectra of stars in the ~200 Myr LMC globular cluster, NGC 1866, reveal rapidly rotating stars with variable H-alpha emission and absorption, and signatures of outflowing material. The variable H-alpha line can substanti ally affect photometric measurements obtained with HST/WFC3 narrow-band filters.
