HAT-P-12 b, also called GSC 03033-00706 b is an extrasolar planet in the constellation Canes Venatici, orbiting the orange dwarf star (K) HAT-P-12. It is located approximately 464.77 light-years away from Earth, or what would be the same, 142.5 parsecs. Continue Reading
An extrasolar planet orbiting in transit by the V = 10.8 mag F8 dwarf GSC 2.792 to 01.700, with a period P = 2.775960 + – 0.000003 d, transit epoch Tc = 2.455.027.59293 + – 0.00031 ( BJD ) and Continue Reading
HAT-P-25 is a G-type main sequence star about 990 light-years away. It has a very low flare activity. The star is enriched in heavy elements, with about twice as many metals compared to solar abundance. In 2010, a hot transiting Continue Reading
HAT-P-23 is a G-type main sequence star about 1200 light-years away. It has a rapid rotation (rotation period equal to 7 days) for its advanced age of 4 billion years and exhibits strong starspot activity. The star may be in Continue Reading
HAT-P-36 b is a gas giant exoplanet orbiting a G-type star. Its mass is 1.8482 Jupiter, it takes 1.3 days to complete an orbit of its star and it is 0.0241 AU from its star. Its discovery was announced in Continue Reading
HAT-P-35 b is a gas giant exoplanet orbiting an F-type star. Its mass is 1.056 Jupiter, it takes 3.6 days to complete an orbit of its star and it is 0.04978 AU from its star. Its discovery was announced in Continue Reading
HAT-P-34 b is an exoplanet orbiting the star HAT-P-34, it was discovered in 2012 by the transit method. https://iopscience.iop.org/article/10.1088/0004-6256/144/1/19 Observations of HAT-P-34b Date: 23/06/2016 ETD Transit Exoplanet Database Collaborative projects
HAT-P-32b orbits the bright star GSC 3281-00800 V = 11.289, with a period P = 2.150008 d. Stellar and planetary masses and radii depend on the eccentricity of the system, which is poorly limited due to the fluctuation of the Continue Reading
HAT-P-30, also known as WASP-51, is the principal of a binary star system about 700 light-years away. It is a G-type main sequence star. The age of the star is much younger than that of the Sun. HAT-P-30 has a Continue Reading
HAT-P – 28b orbits a dwarf star V = 13.03 G3 with a period P = 3.2572 d and has a mass of 0.63 + – 0.04 MJ and a radius of 1.21 + 0.11 -0.08 RJ producing an average Continue Reading
