BV(RI)c light curves of NSVS 5066754
Listed in IVOA Registry (Virtual Observatory)
BVR_c_I_c_ light curves of NSVS 5066754 were taken on 2014 May at Dark Sky Observatory in North Carolina.
Description
This variable is a solar-type eclipsing binary (T1~5750K) with a period of only 0.3751689(1) days. It appeared to be one of the shortest periods in Shaw's list of near-contact binaries.
The Binary Maker fits and our Wilson-Devinney solutions show that the binary could have both semidetached and marginal contact binary configurations. Five new times of minimum light were calculated, along with two minima determined from archived All Sky Automated Survey observations. From these minima and the discovery epoch, a quadratic ephemeris was determined.

Thus, a magnetic braking scenario is possible. Both semidetached and contact models were explored. A marginal contact solution had the best sum of square residuals.
It gave a mass ratio of ~0.5, and a component temperature difference of ~360K, albeit somewhat large for a contact binary. Two substantial cool spots were determined in this solution with 37{deg} and 28{deg} radii and t-factors or 0.94 and 0.78 respectively. The fill-out is very shallow, ~106%.
It may have recently achieved contact.
