discov_num notes refcode
YR 23 Triple. The RV amplitude of 9.5 km s-1 and double lines seen in GCS
cannot be caused by the visual system YR 23 with estimated period of
~50 yr which could however be responsible for dmu. Tok2012a
The Hipparcos parallax, individual magnitudes and standard relations Tok2018a
for main-sequence stars leads to masses of 1.14, 0.96 and 0.80 \msun
for A and the unresolved Ba and Bb pair.
Ba,Bb is estimated to have a dM in V band of 1.2 and a maximum
separation of 26 mas.
