V907 Sco Switched to the Eclipsing Mode Again

Autor: Zasche, P., Vokrouhlický, D., Barlow, B. N., Mašek, M.

Publikováno v: AJ, 165, 81Z (2023)

V907 Scorpii is a unique triple system in which the inner binary component has been reported to have switched on and off eclipses several times in modern history. In spite of its peculiarity, observational data on this system are surprisingly scarce.
