Published in 2018 at "Astronomy Reports"

DOI: 10.1134/s1063772918100049

Abstract: The results of many-year photometric observations of the weak-line T Tauri star V715 Per in the optical (V RI) and infrared (JHK) photometric bands are presented. The period of the star’s lowamplitude brightness variations in… read more here.
