THE SWIFT UVOT STARS SURVEY. II. RR LYRAE STARS IN M3 AND M15

ABSTRACT We present the first results of a near-ultraviolet (NUV) survey of RR Lyrae stars from the Ultraviolet Optical Telescope (UVOT) on board the Swift Gamma-ray Burst Mission. It is well-established that RR Lyrae stars have large amplitudes in the far- and near-ultraviolet. We have used UVOT�...
