Crisp, clear images of a “hot Jupiter” system captured by a University of Notre Dame physicist were vital in determining that a newly found planet inhabits a three-star system, a phenomenon documented only a few times before.
Justin R. Crepp, Freimann Assistant Professor of Physics, was part of the team that discoveredKELT-4Ab, a so-called “hot Jupiter” because it is a gas giant that orbits extremely close to one of the stars in its solar system. The discovery was published in The Astronomical Journal.
While the KELT, or Kilodegree Extremely Little Telescope, detected the likely presence of the planet now called KELT-4Ab about 685 light years from Earth, Crepp was able to capture crisp, clear images of the system, discovering that the planet was in fact a member of a triple star system — one of only a few found to date.
