Stellar Notes
Complex system with HR 7776, CPM at 205". ADS 13717A is occultation double, 6.2 - 8.3v, sep. 0.8"; also 7.2, 7.2v, | sep. 0.05". Component B, 10.2v, A1, binary with A at 0.9". A is astrometric binary. The close occultation pair is | questioned; it has not been confirmed by speckle interferometry.
ADS 13717A = component B of multiple star of which HR 7776 is component A. 8.6780d, K 37.9k/s, asini 4.22. These are | components BC of triple spectroscopic system with HR 7776. BC sep. 0.0225", mag. diff 1.1. BC could be eclipsing. | Component C of the spectroscopic triple system is not the same as any of the visual components of ADS 13717 listed by | Worley; nor is it component C of the components Worley lists for HR 7776 = STF 52.
