LAF 76 | AB: Wu et al. (2015) estimate the B component has spectral type | |
L2 +/- 1, Teff 2000 +/- 100K, and mass 0.012-0.015 Msun. | WuY2015b | |
LAF 76 | Aa,Ab: Lafreniere et al. (2008) obtained AO imaging and spectroscopy | Laf2008b |
of the young star 1RXS J160929.1-210524 and its planetary-mass | ||
candidate companion. Spectral types of the primary and companion are | ||
K7V +/- 1 andf L4 +1/-2, masses are 0.85 +0.20/-0.10 Msun and 8 +4/-2 | ||
Mjup. Projected separation is ~330 au, assuming a distance of 150pc. | ||
Aa,Ab: Primary is the pre-main sequence star 1RXS J160929.1-210524. | ||
Kraus et al. (2014) estimate mass of the companion at 10 +/- 2 Mjup. | KsA2014 |
