Discovery of Stellar Duplicity of TYC 0755-02073-1 During Asteroidal Occultation by (191) Kolga
Abstract
An occultation of TYC 0755-02073-1 by the asteroid (191) Kolga on 2018 February 9 showed this star to be a double star. Both components of the double star were occulted as recorded by seven observers and one or the other component of the double star was occulted as recorded by three observers. There were five miss observations. The separation of the two components is 0.021 ± 0.0011 arcseconds at a position angle of 106.7 ± 3.5 degrees. The magnitude of the primary component is estimated to be 12.96 v ± 0.05. The magnitude of the secondary component is estimated to be 13.03 v ± 0.05.
