Mysterious ripples racing through planet-forming disk discovered
Astronomers have discovered mysterious ripples moving at the speed of 10 km per second across a planet-forming disk -- providing valuable clues about how planets form inside these star-surrounding disks.
Washington: Astronomers have discovered mysterious ripples moving at the speed of 10 km per second across a planet-forming disk -- providing valuable clues about how planets form inside these star-surrounding disks.
These never-before-seen features were seen within the dusty disk surrounding the young, nearby star AU Microscopii (AU Mic).
The fast-moving, wave-like structures are unlike anything ever observed, or even predicted in a circumstellar disk, researchers noted,
who used NASA’s Hubble Space Telescope and the European Southern Observatory’s (ESO) Very Large Telescope in Chile for these findings.
AU Mic is located 32 light-years away in the southern constellation Microscopium. It is an optimal star to observe because its circumstellar disk is tilted edge-on to our view from Earth.
