Lichtkurve und Elemente von BT Ser.

MAINTZ G.

Abstract (from CDS):

CCD observations of BT Ser (18:38:49.67 +04:50:00.45) were obtained at my private observatory. During 5 following nights in June and 2 in August 2012 874 images were collected and a lightcurve of the whole period was received. I found, that BT Ser is a RR lyrae star of type RRab. The first epoch is 2456134.4574 JD. Its period is determined to 0.7243992 d. The GCVS (Samus, 2011) gives for BT Ser the type RRc and a period of 0.378 d.
