Well, this is interesting... Two planets/brown dwarf + planet (19.2 MJ + 8 MJ) found orbiting HW Virginis. The transiting binary system consists of a subdwarf B star (post-red giant star) + red dwarf. This is the first discovery using the eclipse timing method. Also, the planets are circumbinary making them the first known circumbinary planets to have formed from a protoplanetary disk (the first circumbinary planet PSR B1620-26 C that orbits a pulsar in M4 was most likely captured along its parent star PSR B1620-26 B by the pulsar).
