First spectroscopically confirmed discovery of an extragalactic T Tauri star
Abstract
We report the first spectroscopic discovery of an extragalactic bona-fide T Tauri star. The object, LTS J054427-692659, is a low-mass, late-type star located within the LMC dark cloud Hodge II 139. It shows Hα emission with an equivalent width of 78 Å, in line with galactic T Tauri stars, but in excess of any main-sequence dwarf star. The only known plausible interpretation of LTS J054427-692659 is a LMC T Tauri star. Based on observations collected at the European Southern Observatory, Chile (ESO No. 62.I-0607, 64.P-0150(C), 66.C-0196(A)).
