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

Keivan Stassun joins leading astronomers to write "Astro2020," a once-in-a-decade guide for astronomy research, prioritizing gargantuan telescopes on the ground and in orbit as well as increased diversity and inclusion. Read More

During a summer of exoplanet discoveries, astronomer Keivan Stassun helps identify new worlds and expand understanding of our own. Read More

Following the NASA Transiting Exoplanet Survey Satellite mission, Vanderbilt astronomer Keivan Stassun leads the next phase of discovery to find atmospheres like our own. 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

Vanderbilt astronomers will carry out detailed studies of nearby stars orbited by planets with the potential to harbor or sustain life. 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
