discov_num notes refcode
LEP 22 AB: HJL1044. HJL1986
AB: A has planet 263d, 3.3 Mjup. Tok2014d
MUG 11 BC: Second-epoch observation of BC indicates the C component is
co-moving; hence HD 40979 is a triple-star system, with the exoplanet
host star being the primary. Assuming a system age of 1 Gyr, I-band
magnitudes yield masses 0.833 +/- 0.011 and 0.380 +/- 0.025 Msun for
B and C. Spectral types are estimated at K3 and M3, respectively. Mug2007b
BC: NLTT 15983, X-ray source. Detection limits for BC (Mugrauer et
al. 2007) show BC is CPM. Mugrauer measure I(B)=7.98, I(C)=11.3, Mug2007b
estimate masses 0.83 and 0.38 for B,C. Tok2014d
