Observations of the pulsating hydrogen: Deficient star BD+13 deg 3224, during 1980 - 1981
Abstract
Observations of BD+13°3224 in the uvby and VRIC systems are presented together with over 500 V or y magnitude observations made in the period 1980 August - 1981 August. A mean light curve is derived and the Barnes-Evans relation is used to estimate the radius from the VRIC photometry.
