A team of astronomers studying distant exoplanets has been found One That seems 8 or a shaped like a football Rugby ball, depending on the frame of your refIrens-Rather than usual The sphere team suspects that it was formed due to the shape of the planet The intense tidal force of its host star.
The planet, discovered in 2014, Called WASP-103b And is About 1,530 light years from Earth. It’s a whip Around him They are less than Earth Day And a little bigger than Jupiter, as well 20 times hotter. But unlike our local gas giant, the planet is rectangular, as described in a recent study Published In astronomy and astrophysics.
“In principle, we would expect a planet 1.5 times the mass of Jupiter to be roughly the same size, so WASP-103b must be very inflated due to heat from its star and other processes,” said lead author Susanna Barros, an astronomer. At the ESA, the Instituto de Astrophysica e Cincius do Espaco in Portugal and at the University of Porto Release.
WASP-103b is called a Hot thursday, Which is a class of exoplanets characterized by Match our local gas giant. The recently analyzed planet is not the first oddly shaped hot Jupiter: In 2019, A football-shaped world called WASP-121b has been found to be a heavy metal leak.
But it was recently discovered that a team of astronomers had discovered the transit light curve of the exoplanet or Some block out When the stars pass through the light From our point of view it is up front. The team features the ExOplanet satellite (Chips), A space telescope has been designed Study The structure of the exoplanet. By combining CHEOPS data with data from the Hubble Space Telescope and the Spitzer Space Telescope, the team learned more about the shape of the distant world..
“It’s unbelievable that Cheops was actually able to reveal this tiny distortion,” said study co-author Jack Lasker, an astrophysicist at the University of Paris Sciences at Letris, ESA. Release. “This is the first time such an analysis has been done, and we can expect that long-term observations will strengthen this observation and lead to a better understanding of the planet’s internal structure.”
Based on WASP-103b’s transit light curve, the team determined how the mass was distributed across the planet. They have seen the internal structure of the planet Similar to Jupiter, Despite having a double radius, they also determined That’s close enough to WASP-103b They are spheres that must be distorted by the tidal force In the shape of an oval.
The team noted that future monitoring of the recently launched WASP-103b Web space telescopes may better limit the radius of the planet. The web Still on the way to his observation point in space, there is Successfully installed Her primary mirror this week.
