HAT-P-54b, a transiting planet orbiting a late dwarf K star in NASA’s K2 mission field. Ground-based photometric light curves were combined with radial velocity measurements to determine the physical parameters of the system. HAT-P-54b has a mass of 0.760 ± Continue Reading
HAT-P-43 b is a gas giant exoplanet orbiting a G-type star. Its mass is 0.662 Jupiter, it takes 3.3 days to complete an orbit of its star and it is 0.0444 AU from its star. Its discovery was announced in Continue Reading
HAT-P-45 b is a gas giant exoplanet orbiting an F-type star. Its mass is 0.892 Jupiter, it takes 3.1 days to complete an orbit of its star and it is 0.0452 AU from its star. Its discovery was announced in Continue Reading
HAT-P-37 b is a gas giant exoplanet that orbits a G-type star. Its mass is 1.169 Jupiters, it takes 2.8 days to complete one orbit of its star, and is 0.0379 AU from its star. Its discovery was announced in Continue Reading
WASP-58 b is a gas giant exoplanet orbiting a G-type star. Its mass is 0.97 Jupiter, it takes 5 days to complete an orbit of its star and it is 0.0562 AU from its star. Its discovery was announced in Continue Reading
In 2012, a hot transiting Jupiter planet, WASP-52b, was detected in a narrow circular orbit. The planet was named Gokturk by Turkish astronomers in December 2019. Its equilibrium temperature is 1,315 ± 35 K [4] and its orbit is well Continue Reading
WASP-56b and WASP-57b have masses of 0.571 + 0.034-0.035 mj and 0.672 + 0.049 up to 0.046 mj, respectively; and radii of 1.092 + 0.035-0.033 rj of WASP-56b and 0.916 + 0.017 to 0.014 rj of WASP-57b. They orbit main Continue Reading
WASP-48b is an extrasolar planet orbiting the star WASP-48 in the constellation Cygnus. The planet was detected using the transit method by the SuperWASP team, which published its discovery in 2011. It revolves around its host star in just 2.14 Continue Reading
WASP-43b is a transiting planet orbiting the young, active, low-mass star WASP-43 in the constellation Sextans. The planet is a hot Jupiter with a mass twice that of Jupiter, but with a radius approximately equal. WASP-43b was flagged as a Continue Reading
From WASP photometry and radial velocities SOPHIE we report the discovery of WASP-40b (HAT-P-27b), a 0.6 Mjup planet that transits its 12th magnitude parent star every 3.04 days. The host star is G-type endings or K-type beginnings and probably has Continue Reading
