ASAS 095221-4329.8 und ASAS 123034-7703.9 - zwei R-CrB-Stern-Kandidaten aus der ASAS-datenbank.

HUEMMERICH S.

Abstract (from CDS):

During an examination of ASAS Misc-type objects, the stars ASAS 095221-4329.8 GSC 07706-00560, 09:52:21.38 -43:29:40.5) and ASAS 123034-7703.9 (GSC 09416-00380, 12:30:34.22 -77:03:52.7) - both of which show semi-regular variability - were found to exhibit significant obscuration events in their V-band lightcurves. Both stars are likely to be red giants undergoing fading events, possibly of DY Per-type. However, spectroscopy of both stars is needed for a conclusive classification. The corresponding entries in the International Variable Star Index (VSX) have been revised accordingly; variability type was set to "RCB:".
