WDS 11572-7922 CVN 45 AD : NOTES

discov_num	notes	refcode
HUE 3	Aa,Ab: The primary is T Cha, a weak-lined T Tauri star (spectral type
	G8) surrounded by a cold disk. At a distance of 108 +/- 9pc, the
	companion detected by Huelamo et al. (2011) is located 6.7 +/- 1.0 au
	from the primary, well within the gap in that star's disk.	Hue2011
KST 1	AE: Based on optical and X-ray spectroscopy, Kastner et al. conclude
	2MASS J11550485-7919108 is a likely CPM companion to the pre-MS
	star/disk system T Cha, with spectral type M3.	Kst2012
