STF1998 51 Lib = xi Sco. Quintuple.
AB: Mt. Wilson spectral type F3s.
Masses and bolometric magnitudes are derived for the two components
of this system by Mason et al. (1999), based on assumed spectral types Msn1999a
and available parallaxes.
AB: H 1 33. AC: H 2 20. MEv2010
AB,C triple solution by Soderhjelm (1999). (Failed HIP solution due to Sod1999
bad pointing with C comp at IFOV edge).
Star C (mag. 7.30, 7", G1V) is in retrograde motion, and ADS 9910
(mags. 7.4-8.0, 11", dG6) is 281" distant and shares proper motion.
Appears to be a common proper motion pair associated with RST3949 Tok2010b
(16278-0822).
AC: Additional notes may be found in Fatou (1941). Fat1941
Mass = 1.53, 1.53, 1.00 \msun for A, B, C, respectively. Tok2020d
Teff = 6532, 6532, 5705 K for A, B, C, respectively.
Physical quintuple with 16044-1127STF1999AB with P ~ 300 kyr.
