WDS 18531-5011 CVN 61 AE : NOTES

discov_num	notes	refcode
MUG 10	Aa,Ab: PZ Tel. Companion shows common proper motion and detected
	orbital motion. Infrared magnitudes are consistent with companion
	being a brown dwarf of mass 28 +12/-4 Mjup and Teff = 2500-2700K.	Mug2010
	Biller et al. (2010) derive spectral types K0, M7 +/- 2, estimated	Bil2010
	masses 1.25 +0.05/-0.20 Msun and 36 +/- 6 Mjup. Age 12 +8/-4 Myr,
	distance 51.5 +/- 2.6 pc. Their JHK magnitudes are derived from 2MASS	TMA2003
	photometry, combined with their magnitude differences.
	PZ Tel. Member of the bet Pic moving group.	Zuc2001b
