... Popper (1959) classified the eclipsing components as B8 V and B9.5 V. According to Wolff and Preston (1978) the primary component (B8) is a HgMn star. Spectroscopic elements were determined by Wyse (1936) from observations made in the years 1934 - 1935 and by Harper (1937) from observations 1935 -1936. ... Rachkovskaya (1985) according to Harper - 2.68 and 2.36 observed the star in the years 1967 -1968 and 1981 - 1982 and obtained the mass ratio q » 1. ...

... 2009: . ... New Wolf-Rayet Type Star. ... It was discovered that the peculiar velocity of the star is about 50km/s, and that it was discarded from a young star cluster. ... Based on the observational data from the 6-m telescope and from other sources, it was shown with high reliability that chemically peculiar stars with strong depressions in their continuum energy distributions possess the magnetic fields and rotation periods 2 and 3 times larger, respectively, than the stars with weak depressions....
