Researchers using the Kitt Peak National Observatory have identified a puffy, low-density 'marshmallow' planet orbiting a cool red dwarf star. Researchers using the Kitt Peak National Observatory have identified a puffy low-density marshmallow planet orbiting a cool red dwarf star Red dwarfs are the most common type of star in the galaxy and are cooler than our sun, but they can give off powerful flares of radiation that would bombard nearby planets with ultraviolet light. These flares could strip the atmosphere off a planet, so it was thought that it would be unlikely to find puffy gas giants orbiting these stars. “Giant planets around red dwarf stars have traditionally been thought to be hard to form,” said lead researcher Shubham Kanodia of the Carnegie Institution for Science in a statement. “So far this has only been looked at with small samples from Doppler surveys, which typically have found giant planets further away from these red dwarf stars. Until now we have not had a large enough sample of planets to find close-in gas planets in a robust manner.” Read more:

Exoplanets come in all sorts of sizes and all sorts of densities, from solid rocky planets like Earth or Mars to super-puff planets discovered by Hubble.Association of Universities for Research in Astronomy (AURA) October 22, 2022 Artist impression of an ultra fluffy gas giant planet orbiting a red dwarf star.October 20th, 2022 at 8:32 PM By Joshua Hawkins Astronomers have discovered a strange “marshmallow” world 580 light-years away from Earth., surprising the astronomers.

"Giant planets around red dwarf stars have traditionally been thought to be hard to form," said study lead author Shubham Kanodia, a researcher at the Carnegie Institution for Science, in a press release . “Giant planets around red dwarf stars have traditionally been thought to be hard to form,” said lead researcher Shubham Kanodia of the Carnegie Institution for Science in a statement. Zamani Kitt Peak National Observatory telescope helps determines that Jupiter -like Planet is the lowest-density gas giant ever detected around a red dwarf. “Giant planets around red dwarf stars have traditionally been thought to be hard to form,” Shubham Kanodia, a researcher with Carnegie Institution for Science’s Earth and Planets Laboratory, said in the press release shared by NOIRLab. “So far this has only been looked at with small samples from Doppler surveys, which typically have found giant planets further away from these red dwarf stars. Until now we have not had a large enough sample of planets to find close-in gas planets in a robust manner. A suite of astronomical instruments was used to make the observations, including the NASA -funded NEID radial-velocity instrument on the WIYN 3.” The researchers think that this unusual planet was able to form because of the composition of its stars and its orbit. However, they have proposed at least one possible reason for the marshmallow world’s density. The star has an unusually low level of heavier elements which could have caused the core of the planet to form more slowly than is typical, making it acquire gas slowly and contributing to its low density. Named TOI-3757 b, the exoplanet is the fluffiest gas giant planet ever discovered around this type of star. But it could also be a result of a slightly wonky orbit. The planet’s orbit seems to be elliptical as well, meaning it comes closer to the star at some times than at others, which would have warmed the planet and caused its atmosphere to puff up further. Current estimations put the density of the planet at an average of 0.5-meter Telescope at Kitt Peak National Observatory in Arizona, astronomers have observed an unusual Jupiter-like planet in orbit around a cool red dwarf star. From there, they rapidly pull in large amounts of neighboring gas to form the giants we know today.27 grams per cubic centimeter, which is less than half the density of Saturn — “or in fact, similar in density to a marshmallow,” as NOIRLab writes. The researchers plan to make more observations of the planet using the James Webb Space Telescope, looking at its atmosphere in particular. Red dwarf stars are the smallest and dimmest members of so-called main-sequence stars — stars that convert hydrogen into helium in their cores at a steady rate. And they plan to search for other similar planets. Future observations of the marshmallow world, perhaps with the. More on strange planets:. “Finding more such systems with giant planets — which were once theorized to be extremely rare around red dwarfs — is part of our goal to understand how planets form,” said Kanodia. This can strip orbiting planets of their atmospheres, making this star system a seemingly inhospitable location to form such a gossamer planet. The research is published in The Astronomical Journal.
