WDS 00057+4549 STT 547 BP : NOTES
 
 
discov_num notes refcode
STT 547 Premature orbits have been computed. Motion direct.
Both A and B have variable RV (ranges 45 and 25 km/s, respectively).
Another star (9.9, 330") has common proper motion.
AB: Bolometric corrections and component masses determined from
M-L relation. A family of possible orbits were determined by Kiyaeva Kiy2001
(2001) for the F component relative to AB pair (Note: only the
shortest-period solution is presented in orbit catalog.)
AB: NLTT 172/173 Chm2004
AD and AE: Optical pairs, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
AF: HIP 473 + HIP 428.
AC and AD: Rectilinear solution by Pavlovic et al. (2013). Pal2013
POP 217 AP: Rectilinear solution by Cvetkovic (2011). Cve2011d

Chm2004 versions of 2MASS and UCAC, with date given only as "circa 2000". Measures
Chm2004 identical to discovery observations - predominantly close pairs - were assumed
Chm2004 not new observations, so not included in WDS. Similar concerns when primary and
Chm2004 secondary magnitudes or proper motions were the same.)
