Radio Astronomers Discover Saturn-Sized Exoplanet around Ultracool Dwarf 0
- From Around the Web, Space
- August 6, 2020
Astronomers using NSF’s Very Long Baseline Array, a continentwide system of 10 radio telescope antennas located between Hawaii and Puerto Rico, have detected a giant exoplanet in orbit around the ultracool dwarf TVLM 513-46546 (TVLM 513 for short). This is the first astrometric detection of a planet at radio wavelengths. The presence of this Saturn-like planet on a close circular orbit around tiny star represents a challenge to the current planet formation theory.
