An international team of astronomers, driven by astrophysicist Brett Addison from the University of Southern Queensland’s Centre for Astrophysics in Toowoomba, Australia have found a new planet called TOI-1431b.
However, the welcome it offers is a bit too hot for human visitors, or matter of certainty, for anything, truly. TOI-1431b is one of the hottest planets ever discovered.
The newfound world TOI-1431b, also known as MASCARA-5b, is located about 490 light-years away from Earth. It is pretty big — It’s 3 times more huge than the Solar system’s largest planet, Jupiter!
It orbits closely around a relatively bright and very hot star roughly every 2 and a 1/2 days.
TOI-1431b was 1st flagged by NASA’s Training Exoplanet Survey Satellite as a possible planet in late 2019. Follow-up observations assisted researchers to confirm the planet’s existence.
TOI-1431b was an extremely hot planet, even warmer than some red dwarf — the smallest, coolest, and most common type of star in our Milky Way galaxy, Dr. Addison, a University of Southern Queensland astrophysicist, said.
Such exceptionally hot places are known as ultra-hot Jupiters, and they are very uncommon. Astrophysicist Dr. Brett Addison, who drove the study, described TOI-1431b as “a hellish world”.
“The discovery presents a great opportunity to study the atmospheres of these planets to understand how they form and migrate. TOI-1431b did not form that close to its star – it formed much further away and then migrated into this really tight orbit.”
TOI-1431b was made even more unusual due to its retrograde orbit, Dr. Addison added.
“If you look at the Solar System, all the planets orbit in the same direction that the Sun rotates and they’re all along the same plane. This new planet’s orbit is tilted so much that it is actually going in the opposite direction to the rotation of its host star,” he explained.
