WASP-10 is a star in the constellation Pegasus. The SuperWASP project has observed and classified this star as a variable star, perhaps due to the eclipsing planet.
The star is likely older than Sun, has fraction of heavy elements close to solar abundance, and is rotating rapidly, being spun up by the tides raised by the giant planet on the close orbit.
