Abstract (from CDS):

We report the discovery of WASP-43b, a hot Jupiter transiting a K7V star every 0.81d. At 0.6-M☉ the host star has the lowest mass of any star currently known to host a hot Jupiter. It also shows a 15.6-d rotation period. The planet has a mass of 1.8MJup, a radius of 0.9RJup, and with a semi-major axis of only 0.014AU has the smallest orbital distance of any known hot Jupiter. The discovery of such a planet around a K7V star shows that planets with apparently short remaining lifetimes owing to tidal decay of the orbit are also found around stars with deep convection zones.
