Period decrease in three SuperWASP eclipsing binary candidates near the short-period limit
Period decrease in three SuperWASP eclipsing binary candidates near the short-period limit
SuperWASP light curves for 53 W UMa-type eclipsing binary (EB) candidates, identified in previous work as being close to the contact binary short-period limit, were studied for evidence of period change. The orbital periods of most of the stars were confirmed, and period decrease, significant at more than 5σ, was …
