Exoplanet

Aging stars expand and eventually destroy planets in their inner systems. Or do they? A team of researchers that includes Keivan Stassun finds evidence of a planet that survived its star’s transformation, and that is reshaping our understanding of planetary and stellar evolution. Read More

A groundbreaking study, using data from NASA and a technique pioneered by a Vanderbilt professor, is giving humankind a glimpse at a distant exoplanet with a size similar to Earth and a surface which may resemble Mercury or Earth’s Moon. Located nearly 49 light-years from Earth, the planet known… Read More

Astronomers at Vanderbilt and Ohio State have discovered a planet like Jupiter zipping around its host star every day, boiling at temperatures hotter than most stars with a giant cometary tail. Read More

Astronomers from Vanderbilt, Lehigh and Ohio State universities have discovered a “puffy planet" with the density of Styrofoam that is an excellent test-bed for probing exoplanets for signs of life. Read More

A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet in another solar system 700 light years away. The discovery was made using inexpensive ground-based telescopes, including one specially designed to detect exoplanets and jointly operated by astronomers at Ohio State University and Vanderbilt University.

The smallest exoplanets yet discovered orbit a dwarf star almost identical to Barnard’s star, one of the Sun’s nearest neighbors. The similarity helped the astronomers calculate the size of the distant planets. Read More
