WDS 19409-0152 TOK 424 (HD 185785) : NOTES
 
 
discov_num notes refcode
TOK 424 HIP 96834 has a spectroscopic orbit with a period of 1yr and expected
semi-major axis of 27mas (Latham 2012, private communication). We
resolved this pair, although the measurement near the diffraction
limit is uncertain. There are some unsolved questions, however. Why,
despite the small magnitude difference dy = 1.2 mag, were double lines
not seen? Why, despite the 1-yr period, was the Hipparcos parallax not
strongly affected and the star appears to be on the main sequence? Tok2015c
