Abstract:
We present light curves and periods of 53 candidates for short period
eclipsing binary stars identified by SuperWASP. These include 48 newly
identified objects with periods <2x104s (∼0.23d), as well as the
shortest period binary known with main sequence components
(GSC2314-0530 = 1SWASP J022050.85+332047.6) and four other
previously known W UMa stars (although the previously reported periods
for two of these four are shown to be incorrect). The period
distribution of main sequence contact binaries shows a sharp cut-off
at a lower limit of around 0.22d, but until now, very few systems
were known close to this limit. These new candidates will therefore be
important for understanding the evolution of low mass stars and to
allow investigation of the cause of the period cut-off.
Description:
The catalog contains the list of 53 candidate short period eclipsing
binaries. The SuperWASP ID encodes the J2000 position of the star as
1SWASP Jhhmmss.ss±ddmmss.s. In the table we list the RA and Dec of
each object extracted from the SuperWASP ID. We also list the orbital
period in days, the peak magnitude of the object in the SuperWASP
V-band, along with the depths (in magnitudes) of the primary and
secondary minima.
