RR Gem und SZ Gem - zwei interessante RR Lyr - Sterne.
STEINBACH H.-M.
Abstract (from CDS):
An overview on the longterm O-C-behaviour of the RRab-stars RR Gem and SZ Gem are given. RR Gem showed three sections with nearly constant periods during the last 107 years, whereas the shape of SZ Gem's O-C-curve might indicate a light-time-effect due to motion in an eccentric orbit within a double-star-system. Both stars are recommended for further observations.
