    Discovery

    KELT-10b was discovered by a group of scientists at the SAAO using the KELT-South telescope. The light curves and parameters of the system were observed, and it is predicted that due to the host's activity and evolution state along the HR Diagram, the planet is bloated. KELT-10b is part of a group of exoplanets that will be observed by the ESA mission ARIEL. [2]

    Properties

    KELT-10b has 68% the mass of Jupiter, but is about 40% larger than the Jovian planet. The planet is less dense than Jupiter due to its mass, and has an equilibrium temperature of 1,377  K . KELT-10b has a typical four-day orbit around its host at a separation about ten times greater than Mercury, but is unknown if it's orbiting on a circular or an elliptical one. [1] Observations of the planet with the Very Large Telescope resulted in the discovery of the presence of sodium in the atmosphere. [3]

    The Hungarian Automated Telescope Network (HATNet) project is a network of six small fully automated "HAT" telescopes. The scientific goal of the project is to detect and characterize extrasolar planets using the transit method. This network is used also to find and follow bright variable stars. The network is maintained by the Center for Astrophysics | Harvard & Smithsonian.

    The XO Project is an international team of amateur and professional astronomers tasked with identifying extrasolar planets. They are led by Peter R. McCullough of the Space Telescope Science Institute. It is primarily funded by NASA's Origins Program and the Director's Discretionary Fund of the Space Telescope Science Institute.

    WASP-43b, formally named Astrolábos, is a transiting planet in orbit around the young, active, and 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 roughly equal radius. WASP-43b was flagged as a candidate by the SuperWASP program, before they conducted follow-ups using instruments at La Silla Observatory in Chile, which confirmed its existence and provided orbital and physical characteristics. The planet's discovery was published on April 14, 2011.

    The Kilodegree Extremely Little Telescope is an astronomical observation system formed by two robotic telescopes that are conducting a survey for transiting exoplanets around bright stars. The project is jointly administered by members of Ohio State University Department of Astronomy, the Vanderbilt University Department of Physics and Astronomy Astronomy Group, the Lehigh University Department of Physics, and the South African Astronomical Observatory (SAAO).

    KELT-2Ab is an extrasolar planet that orbits the star KELT-2A approximately 440 light-years away in the constellation of Auriga. It was discovered by the KELT-North survey via the transit method, so both its mass and radius are known quite precisely. As of its discovery KELT-2Ab is the fifth-brightest transiting Hot Jupiter known that has a well constrained mass. This makes the KELT-2A system a promising target for future space- and ground-based follow-up observations to learn about the planet's atmosphere.

    KELT-10, also known as CD−47°12635, is a sun-like star in the southern constellation Telescopium. It has an apparent magnitude of 10.62, making it readily visible in telescopes, but not to the naked eye. Parallax measurements from the Gaia spacecraft place the star at a distance of 617 light years; it is currently receding with a radial velocity of 31.6 km/s.
