Speckle interferometry of tau Persei.
Abstract
Together with the Colacevich (1941) spectroscopic orbit for the 4.15-year, spectroscopic binary star Tau Persei, six new speckle interferometric observations are used to determine the elements of the apparent orbit. The elements determined are a high inclination, of 95 deg, for the orbit, and a semimajor axis of 0.050 arcsec. Although these values are not consistent with an existing astrometric study of the system, they lead to astrophysical self-consistency among the mass and luminosity parameters. It is speculated that the system may exhibit a partial eclipse at one phase of its orbit.
