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 H
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.
Key words: stars: pre-main sequence -- stars: late-type -- Magellanic Clouds
