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
HAT-P-7b (or Kepler-2b) is an extrasolar planet discovered in 2008. It orbits very close to its host star, and is both larger and more massive than Jupiter. Due to the extreme heat it receives from its star, the day-side temperature Continue Reading
HAT-P-55 b is a gas giant exoplanet orbiting a G-type star. Its mass is 0.582 Jupiter, it takes 3.6 days to complete an orbit of its star and it is 0.04604 AU from its star. Its discovery was announced in Continue Reading
