Hubble spots a distant planet that is literally being vaporized – BGR

We usually think of planets as having a certain level of permanence but for worlds that reside within very close proximity of a star existence can be fleeting. En bestemt type of exoplanet dat astronomen proberen om te leren meer over zijn de zogenaamde "hot neptunes", die zijn superheated gianten die zijn ongelooflijk rare. Nu, onderzoekers die de Hubble Space Telescope hebben pinpointed wat ze geloven te zijn a planet just on the cusp of being considered a hot Neptune, and it's so close to its star that the planet is actually evaporating right before our eyes. The exoplanet, called GJ 3470b, is located near what researchers call the "Hot Neptune Desert" around its host star. Scientists believe that there are a lack of such planets because they are completely destroyed over time due to their close relationship with the stars they orbit, and GJ 3470b might be the next to go. One of GJ 3470b's fellow planets is GJ 436b, which astronomers believe is losing its atmosphere as its star strips it away. Scientists think that 436b will survive the ordeal without being completely destroyed, but 3470b is in a much tougher spot. 3470b is being stripped of mass 1 00 times faster than 436b, and it is possible that the planet will be completely vaporized.

We usually think of planets as having a certain level of permanence but for worlds that reside within very close proximity of a star existence can be fleeting. En bestemt type of exoplanet dat astronomen proberen om te leren meer over zijn de zogenaamde “hot neptunes”, die zijn superheated gianten die zijn ongelooflijk rare.

Nu, onderzoekers die de Hubble Space Telescope hebben pinpointed wat ze geloven te zijn a planet just on the cusp of being considered a hot Neptune, and it’s so close to its star that the planet is actually evaporating right before our eyes.

The exoplanet, called GJ 3470b, is located near what researchers call the “Hot Neptune Desert” around its host star. Scientists believe that there are a lack of such planets because they are completely destroyed over time due to their close relationship with the stars they orbit, and GJ 3470b might be the next to go.

One of GJ 3470b’s fellow planets is GJ 436b, which astronomers believe is losing its atmosphere as its star strips it away. Scientists think that 436b will survive the ordeal without being completely destroyed, but 3470b is in a much tougher spot. 3470b is being stripped of mass 1

00 times faster than 436b, and it is possible that the planet will be completely vaporized.

“Vincent Bourrier of the University of Geneva and co-author of the work, said in a statement. “It’s one of the most extreme examples of a planet undergoing a major mass-loss over its lifetime. Deze sizable massaverlies heeft belangrijke gevolgen voor zijn evolutie, en het beïnvloedt ons begrip van de oorsprong en de vijand van de populatie van exoplaneten dicht bij hun sterren. “

Dus hoe dicht is te dicht bij het planeten en hun sterren? The nearest planet to our own Sun, the scorching-hot Mercury, has made a go of it for a long time, but 3470b is much closer to its star. In fact, both 436b and 3470b are just one tenth the distance from their star than Mercury is from the Sun.
