NASA project to search for planets detected a planet the size of Neptune, which rotates around its young star with incredible speed: one revolution for earth week. When this star pours a planet of violent outbreaks.
The new planet, called b AU Microscopii, AU Mic, or b for short, was discovered by the space telescope Transiting Exoplanet Survey Satellite (TESS) Spitzer and. The discovery will help scientists better understand how planets evolve, how their atmosphere and how they interact with their stars.
AU Mic is a young, dwarf star, featuring powerful flashes. She is only 20-30 million years (probably 22 million). Such stars are the favorite objects to study because their small size makes it easier to detect planets in orbits.
AU Mic b is hardly habitable, given its size and aggressiveness of the star around which the planet rotates. AU Mic b makes one revolution around its star in 8.5 earth days, and its mass is about 58 times the mass of our planet.
The star and its planet the size of Neptune located at the distance of almost 32 light years from Earth. It’s relatively close. The system is part of a young stellar group called the Beta Pictoris Moving Group.
“We believe that AU Mic b formed far from the star and migrated inside of the system on its current orbit. This can happen when the planets gravitationally interact with the gas disk or with other planets,” says study co-author and researcher TESS Thomas Barclay.
Find AU Mic b was difficult, given how active the star, and the fact that the light is covered with spots — dark areas that give rise flare, similar from afar on the planet.
The Spitzer telescope has confirmed two of the transit of the planet across the disk of stars, and on the basis of the received data, scientists have determined that the planet is 8% more Neptune.
Scientists suspect that in the system AU Mic is still a planet. “In these TESS have a feasible transit, and we hope TESS will be re-directed to AU Mic this year,” says the study’s lead author Peter Plavcan, associate Professor of the Department of physics and astronomy at George Mason University.
