WDS 02407+2637 STT 43 (HD 16638) : NOTES
 
 
discov_num notes refcode
STT 43 Scardia et al. (2001) orbit considered preliminary because the arc of Sca2001d
the observed orbit is only 90 degrees and is placed completely around
aphelion. The Hipparcos parallax of 0".01385 +/- 0.00125 gives a mass
sum of 3.1 Msun, an overestimate for a star of type F7V. The dynamical
parallax of 0".0149 agrees well with the measured one.
