K型主系列星
This is a triple system with three stars that are all less massive than the Sun. The brightest component is designated HD 16160, and is known as Gliese 105 A. It is a K-type main-sequence star, about 70% the mass of the Sun. This star is unusual because its eruptions appear to not conform to the Waldmeier Effect - i.e. strongest eruptions of HD 16160 are not the ones characterized by the fast eruption onset.
