چکیده

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

HAT-P-44b, HAT-P-45b, AND HAT-P-46b: THREE TRANSITING HOT JUPITERS IN POSSIBLE MULTI- PLANET SYSTEMS

We report the discovery by the HATNet survey of three new transiting extrasolar planets orbiting moderately bright (V=13.2, 12.8 and 11.9) stars. The planets have orbital periods of 4.3012, 3.1290, and 4.4631 days, masses of 0.39, 0.89, and 0.49MJ, and radii of 1.28, 1.43, and 1.28RJ. The stellar hosts have masses of 0.94, 1.26, and 1.28M⊙. Each system shows significant systematic variations in...

HAT-P-5b: A JUPITER-LIKE HOT JUPITER TRANSITING A BRIGHT STAR

We report the discovery of a planet transiting a moderately bright (V = 12.00) G star, with an orbital period of 2.788491± 0.000025 days. From the transit light curve we determine that the radius of the planet is Rp = 1.257± 0.053RJup. HAT-P-5b has a mass of Mp = 1.06± 0.11MJup, similar to the average mass of previously-known transiting exoplanets, and a density of ρp = 0.66± 0.11 g cm. We find...

HAT-P-7b: AN EXTREMELY HOT MASSIVE PLANET TRANSITING A BRIGHT STAR IN THE KEPLER FIELD

We report on the latest discovery of the HATNet project; a very hot giant planet orbiting a bright (V = 10.5) star with a small semi-major axis of a = 0.0377± 0.0005AU. Ephemeris for the system is P = 2.2047299 ± 0.0000040 days, mid-transit time E = 2, 453, 790.2593 ± 0.0010 (BJD). Based on the available spectroscopic data on the host star and photometry of the system, the planet has a mass of ...

HAT-P-2b: A SUPER-MASSIVE PLANET IN AN ECCENTRIC ORBIT TRANSITING A BRIGHT STAR

We report the discovery of HAT-P-2b, a massive (Mp = 8.17 ± 0.72 MJup) planet transiting the bright (V = 8.7) F8 star HD 147506, with an orbital period of 5.63 days and an eccentricity of e = 0.5. From the transit light curve we determine that the radius of the planet is Rp = 1.18 ± 0.16 RJup. HAT-P-2b has a mass about 9 times the average mass of previously-known transiting exoplanets, and a de...
