WASP-19, formally named Wattle, is a magnitude 12.3 star about away, located in the Vela constellation of the Southern Hemisphere. This star has been found to host a transiting hot Jupiter-type planet in a tight orbit.
WASP-19 is older than the Sun, has a fraction of heavy elements above the solar abundance, and is rotating rapidly, being spun up by the tides raised by the giant planet on a close orbit.
