The ephemeris of the pulsating Helium star BX Cir.

KILKENNY D. and WORTERS H.L.

Abstract (from CDS):

Twenty-eight new timings of maxima of the radially pulsating extreme helium (EHe) star BX Cir (=LSS3184) obtained during 2005-2013 are reported. These results almost double the baseline of observations of the pulsations to 20yr, determine the period decrease rate at dP/dn = -3.47x10–10d, and better define the ephemeris for pulsation maximum. No evidence for ephemeris terms higher than quadratic is found.
