HAT-P-58b -- HAT-P-64b: Seven Planets Transiting Bright Stars

2021 
We report the discovery and characterization of 7 transiting exoplanets from the HATNet survey. The planets, which are hot Jupiters and Saturns transiting bright sun-like stars, include: HAT-P-58b (with mass M_p = 0.37 M_J, radius R_p = 1.33 R_J, and orbital period P = 4.0138 days), HAT-P-59b (M_p = 1.54 M_J, R_p = 1.12 R_J, P = 4.1420 days), HAT-P-60b (M_p = 0.57 M_J, R_p = 1.63 R_J, P = 4.7948 days), HAT-P-61b (M_p = 1.06 M_J, R_p = 0.90 R_J, P = 1.9023 days), HAT-P-62b (M_p = 0.76 M_J, R_p = 1.07 R_J, P = 2.6453 days), HAT-P-63b (M_p = 0.61 M_J, R_p = 1.12 R_J, P = 3.3777 days), and HAT-P-64b (M_p = 0.58 M_J, R_p = 1.70 R_J, P = 4.0072 days). The typical errors on these quantities are 0.06 M_J, 0.03 R_J, and 0.2 seconds, respectively. We also provide accurate stellar parameters for each of the hosts stars. With V = 9.710±0.050mag, HAT-P-60 is an especially bright transiting planet host, and an excellent target for additional follow-up observations. With Rp = 1.703±0.070 R_J, HAT-P-64b is a highly inflated hot Jupiter around a star nearing the end of its main-sequence lifetime, and is among the largest known planets. Five of the seven systems have long-cadence observations by TESS which are included in the analysis. Of particular note is HAT-P-59 (TOI-1826.01) which is within the Northern continuous viewing zone of the TESS mission, and HAT-P-60, which is the TESS candidate TOI-1580.01.
