Abstract: We report the discovery of the transiting extrasolar planet HAT-P-49b. The planet transits the bright (V = 10.3) slightly evolved F-star HD 340099 with a mass of 1.54 M⊙and a radius of 1.83 R ⊙ . HAT-P-49b is orbiting one of the 25 brightest stars to host a transiting planet which makes this a favorable candidate for detailed follow-up. This system is an especially strong target for Rossiter-McLaughlin follow-up due to the host star’s fast rotation, 16 km s-1. The planetary companion has a period of 2.6915 days, mass of 1.73 M J, and radius of 1.41 R J. The planetary characteristics are consistent with that of a classical hot Jupiter but we note that this is the fourth most massive star to host a transiting planet with both Mp and Rp well determined. © 2014.
