Abstract:
We present new V-band differential photometry and radial velocity
measurements of the unevolved, 1.18 day period, F+G-type, double-lined
eclipsing binary VZ Cep. We determine accurate values for the absolute
masses, radii, and effective temperatures.
Description:
VZ Cep was placed on the observing list at the Harvard-Smithsonian
Center for Astrophysics (CfA) in 2003 January, and was observed until
2007 June with an echelle spectrograph on the 1.5m Tillinghast
reflector at the F.L. Whipple Observatory (Mount Hopkins, AZ).
