| 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. |
