An exoplanet near ultracool star

New record in astrometry and exoplanetology – the authors of 0906.0544 are talking about discovery of the planet in the vicinity of a very light star. The mass of the star is about 0.07 Solar masses, i.e., equivalent to 3-9 Jupiter masses – it is actually near the lower mass limit for an object to be called a star

The star itself have a temperature about 2700 K, its planet – about 400 K. Both objects have a similar apparent size – around 0.1 radius of the Sun – so the system looks almost like a double star.

The discovered system – VB10 – is denoted by red star

By the way, since the system is rather close to us (about 6 Pcs), it might be possible to resolve it with new generation interferometer devices (angular distance between te objects on the sky is around 60 milliarcsec). Right now, one can only study the system by astrometric methods.
