HAT-P-13 photometry follow-up

DOI

We report on the discovery of a planetary system with a close-in transiting hot Jupiter on a near circular orbit and a massive outer planet on a highly eccentric orbit. The inner planet, HAT-P-13b, transits the bright V=10.622 G4 dwarf star GSC 3416-00543 every P=2.916260+/-0.000010 days, with transit epoch T_c_=2454779.92979+/-0.00038 (BJD) and duration 0.1345+/-0.0017 days. The outer planet HAT-P-13c orbits the star every P_2_=428.5+/-3.0 days with a nominal transit center (assuming zero impact parameter) of T_2c_=2454870.4+/-1.8 (BJD) or time of periastron passage T_2,peri_=2454890.05+/-0.48 (BJD). Transits of the outer planet have not been observed, and may not be present. The host star has a mass of 1.22^+0.05^-0.10_M{sun}, radius of 1.56+/-0.08R{sun}_, effective temperature of 5653+/-90K, and is rather metal-rich with [Fe/H]=+0.41+/-0.08.
