Astronomers see whirlwind around possible exoplanet-in-the-making
An international team of astronomers led by researchers from the Leiden University has discovered a whirlwind of dust and pebbles in orbit around a young star. It is possible that a planet is forming in the pebbles. The team of scientists made the discovery during the time that designers and developers of an astronomical instrument get as a reward for their work. They will soon publish their findings in the journal Astronomy & Astrophysics.
The exoplanet-in-the-making orbits the star HD 163296 in a close orbit. HD 163296 is a young star much studied by astronomers about 330 light-years away from Earth in the constellation of Sagittarius. Previously, astronomers found evidence for the formation of three large exoplanets in a wide orbit around the star. Now, they may be adding a fourth planet close to the star.
