  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 Mp = 0.37 MJ, radius Rp =
1.33 RJ, and orbital period P = 4.0138 days), HAT-P-59b (Mp = 1.54 MJ, Rp =
1.12 RJ, P = 4.1420 days), HAT-P-60b (Mp = 0.57 MJ, Rp = 1.63 RJ, P = 4.7948
days), HAT-P-61b (Mp = 1.06 MJ, Rp = 0.90 RJ, P = 1.9023 days), HAT-P-62b (Mp =
0.76 MJ, Rp = 1.07 RJ, P = 2.6453 days), HAT-P-63b (Mp = 0.61 MJ, Rp = 1.12 RJ,
P = 3.3777 days), and HAT-P-64b (Mp = 0.58 MJ, Rp = 1.70 RJ, P = 4.0072 days).
The typical errors on these quantities are 0.06 MJ, 0.03 RJ, and 0.2seconds,
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 RJ, 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.
