This Neptune-sized planet around a bright A-type star, will rapidly lose its gas. Scientists reveal the reason.
Astronomers are constantly monitoring alien planets. So far, they’ve found thousands of them, but more than 99% of them orbit smaller stars. Only a few of these have been found to have really large orbits starslike A-type stars, which are bright blue stars about twice the size Sun. Most of these observed exoplanets are roughly as large as Jupiter. In the latest developments, astronomers from the University California, Berkeley reported the discovery of a new Neptune-sized planet, called HD 56414 b. New planet has 3.7 times radius The earthdiscovered by NASA’s TESS mission.
Research reveals that it is orbiting one of massive A-type stars would provide hints as to why there are only a handful of such planets, smaller than Jupiter, is orbiting 1 percent of the brightest stars in our galaxy. This newly found planet has a longer orbital period unlike other exoplanets discovered so far with short and fast orbital periods around their stars.
Incredibly, NASA reports that this Neptune-sized planet around a bright A-type star, will rapidly be stripped of gas by harsh stellar radiation and will be condensed into an undetectable core.
“It’s one of the smallest planets we know of around these really massive stars. In fact, it’s the hottest star we know with a planet smaller than Jupiter. The planet. This is interesting first of all because these types of planets are really hard, a phy.org report quotes Steven Giacalone, a UC Berkeley graduate student.
The discovery of a new Neptune-sized planet outside the region where the planet will be stripped of gas suggests that A-type bright stars have several other undiscovered phases that are yet to be discovered. break. The researcher also suggests that the discovery of the planet also adds to the existing understanding of how the planet’s atmosphere evolved.
