discov_num notes refcode
MSH 1 Meshkat et al (2015) resolved a faint companion to HD 984. They derive
a system age in the range 30-200 Myr. Teff for the primary is 6315 +/-
89K; temperature for the secondary is 2777 +127/-130K or 2900 +/- 200K,
depending on adopted scale and synthetic spectra. Spectral types are
F7V and M6.0 +/- 0.5. Primary mass is 1.20 +/- 0.06 Msun; secondary
mass estimates range from 74 - 90 Mjup, depending on adopted models. Msh2015
