Sunlike star 90 ly away in Monoceros with a planet. Star is 1.2 the Sun's radius, 1.3 its mass, and 2.5 BY old. The star is an ideal object of study for the interactions between stars and planets. One of the six extrasolar systems known to have planets to be first shown to also have a dust disk by Spitzer. Planet independently discovered by CORALIE and Carnegie teams and is at least a 1.09 MJ Jovian in a hot eccentric orbit. By analyzing sonic vibrations, oscillations in brightness, through astroseismology, the exact internal spin rate (12 days) and orientation of the star has been computed. Assuming the planet orbits along the star's equator, it's mass can be inferred to be 1.85 Jupiter's, calming some suspicions that it may be a brown dwarf.
