On the period of HR 1362

Abstract

Photoelectric UBV observations, made in 1981 and 1982, of the active star HR 1362 are presented. A period analysis reveals many (all greater than 100 days) probable periods because of the large gaps in the data. If the most probable period around 330 d is true and represents the rotation period, as it does in all other active stars, then HR 1362 would be an extreme case of slow rotation.

Photometric Analysis in Detached Close Binaries with Eccentric Orbits. The Case of RX Her

“…Our photometric analysis is based on the UBV observations of RX Her (420 in each colour) that were carried out in 1988 with the 30 cm telescope of the Ankara University Observatory (Demircan and Derman, 1989).…”
