We investigated two variable stars AH Tau and ZZ Cas. They are eclipsing binaries of W UMa and $\beta$ Lyr types. The period…
We report on the photometric observation of RZ LMi, which is a dwarf nova renowned for its extremely short ( 19 d) and regular…
This paper demonstrates the growing potential of EDMOND, a database of meteor orbital data, by presenting a summary analysis of…
Time-series photometric observations were made for the SX Phoenicis star AE UMa between 2009 and 2012 at the Xinglong Station of…
We present new longitudinal magnetic field and Str ¨ omgren photometric measurements 1 of the Bp star 84 UMa. From these data we…
Among low luminosity galactic X-ray sources, AM Herculis-type binaries form a distinct class. The main characteristics of this…
We have developed a test for the evolutionary state of W Ursae Majoris binaries by comparing the observed spectral type of 31 of…
BE Ursae Majoris is a 15-mag variable star of period 2.29 days, with a sinusoidal light curve of ∼1 mag amplitude1. Recently…
Abstract 15fUMa besitzt ein zusammengesetztes Spektrum (A3 + F5). Im Bereich λ 3550 A bis λ 4900 A wurden die Äquivalentbreiten…
