英文摘要With the 2013 version of W-D code, we derived the photometric solutions for the new discovered.extremely short-period eclipsing binary 1SWASP J024148.62+372848.3 based on its complete RI c light curves. The results show that the system is a W-type overcontact system with a filling-out factor of 23% and a mass ratio of q = 1.23, thus it is a new target which belongs to the rare group of overcontact binary with period under the short period limit (0.22 days). The obviously asymmetries found in its light curves could be explained well by the high spots coverage on the two components which have strong magnetic activities due to their late type nature. A third light contributing about 40% of the total light has been detected during the light curve analysis. This additional component may play an important role in the formation of 1SWASP J024148.62+372848.3, just like those in other overcontact binaries below the limit. (C) 2015 Published by Elsevier BM.
