We report on the latest discovery of the HATNet project: a very hot giant planet orbiting a bright ( -->V = 10.5) star with a small semimajor axis of -->a = 0.0377 ± 0.0005 AU. Ephemeris for the system is -->P = 2.2047299 ± 0.0000040 days, midtransit time -->E = 2,453,790.2593 ± 0.0010 (BJD). Based on the available spectroscopic data on the host star and photometry of the system, the planet has a mass of -->Mp = 1.78+ 0.08−0.05 MJ and radius of -->Rp = 1.36+ 0.20−0.09 RJ. The parent star is a… Expand
