HAT-P-32b and HAT-P-33b: Two Highly Inflated Hot Jupiters Transiting High-jitter Stars

(Hartman, J. D.; Bakos, G. Á.; Torres, G.; Latham, D. W.; Kovács, Géza; Béky, B.; Quinn, S. N.; Mazeh, T.; Shporer, A.; Marcy, G. W.; Howard, A. W.; Fischer, D. A.; Johnson, J. A.; Esquerdo, G. A.; Noyes, R. W.; Sasselov, D. D.; Stefanik, R. P.; Fernandez, J. M.; Szklenár, T.; Lázár, J.; Papp, I.; Sári, P. )

...the discovery of two exoplanets transiting high-jitter stars. HAT-P-32b orbits the bright V = 11.289 late-F-early-G dwarf star GSC 3281-00800, with a period P = 2.150008 ± 0.000001 d. The stellar and planetary masses and radii depend on the eccentricity of the system, which is poorly constrained due to the high-velocity jitter (~80 m s-1). Assuming a circular orbit, the star has a mass of 1.16 ± 0.04 M ⊙ and radius of 1.22 ± 0.02 R ⊙, while the planet has a mass of 0.860 ± 0.164 M J and a radius of 1.789 ± 0.025 R J ...
