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 |
