2016IBVS.6180....1O - IAU Inform. Bull. Var. Stars, 6180, 1-1 (2016/September-0)
RW Arietis, an Eclipsing RR Lyrae Star?
ODELL A. and SREEDHAR Y.
Abstract (from CDS):
RW Arietis is an RRc star which has long been thought to undergo eclipses. We set out to answer the question posed in the title by utilizing extensive datasets, both archival and original, but found nothing, thus effectively answering in the negative. Instead we present the highest quality light curve to date, the first radial velocity curve, and the first successful ephemeris. The pulsation period changed abruptly in 2012, and seems to have changed at least twice before that.
