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., the strongest eruptions of HD 16160 are not the ones characterized by the fast eruption onset.
This star, a K-type main sequence star roughly 70% the mass of our Sun, is unusual because its eruptions do not conform to the Waldmeier effect; specifically, the most powerful eruptions of HD 16160 are not those characterized by rapid eruption onset.
