Stellar components

NSVS 06507557 A is a late type orange dwarf star, close to spectral type M and with two thirds of Sun's mass. The spectral type of NSVS 06507557 B is classed as M3, a dim red dwarf star, with 28 percent of Sun's mass but a bloated radius of 0.44 Solar radii, due to the youth of stellar system. Both stars are very close each other separated by 2.63 Solar radii, roughly one percent the value of 1 Astronomical Unit and take half an Earth's sidereal day to revolve around their ORBit barycentre.
