Gl 425, a slowly rotating BY Dra-type star. (1985). Revista Mexicana De Astronomía Y Astrofísica, 10(1), 329-332. https://astronomia.unam.mx/journals/rmxaa/article/view/1985rmxaa..10..329t

Abstract

The authors observed both components with an intensified Reticon detector at the Cassegrain spectrograph of 1.6 m telescope of the Brazilian Astrophysical Observatory. The brighter component has a filled-in Hα line and the faint companion is a typical dMe star. A spectral classification of dM0e and dM4e is proposed for the pair. An intense flare of Gl 425 was found, indicating that in this aspect it behaves like a normal BY Dra star.
