Detection of an increasing orbital period in the subdwarf B eclipsing system NSVS 14256825.

KILKENNY D. and KOEN C.

Abstract (from CDS):

New timings of eclipses made in 2010 and 2011 are presented for the hot subdwarf B (sdB) eclipsing binary NSVS 14256825. Composed of an sdB star and a much cooler companion, with a period near 0.1104 days, this system is very similar to the prototype sdB eclipsing binary HW Vir. The new observations show that the binary period of NSVS 14256825 is rapidly increasing at a rate of about 12 {x} 10–12 days/orbit.
