  • The early-K star T Cha, a member of the nearby (D ≈ 100 pc) Cha Association, is a relatively "old" (age ~ 7 Myr) T Tauri star that is still sporadically accreting from an orbiting disk whose inner regions are now evidently being cleared by a close, substellar companion. We report the identification, via analysis of proper motions, serendipitous X-ray imaging spectroscopy, and follow-up optical spectroscopy, of a new member of the Cha Association that is very likely a low-mass companion to T Cha… CONTINUE READING
