The properties of a recently discovered planet are so strange that astronomers can’t understand how they got there.
This is called TOI 4860b and it’s located around. 260 light years awayIt’s just a bit smaller than Saturn. So far, everything is normal.
TOI-4860b orbits a tiny star, an ancient one, that is only a third the size of our Sun. Each lap takes just 1.52 hours. It is part of a growing group of strange worlds that are a puzzle. Currently, there are no known formation paths for planets with such bizarre shapes around small stars.
Two papers describe the exoplanet. one submittedThe following are some of the ways to get in touch with us: Astronomy & AstrophysicsThe Other PublishedIn the meantime, Monthly Notices of Royal Astronomical SocietyThe preprint server ArXiv has been updated with the latest version of the paper.
As astronomers discover and confirm more Exoplanets – Nearly 5,500 at the time of writing – curious Gaps are appearingThere are many different types of worlds.
It’s also possible that worlds can appear in unexpected places. It’s like giant planets orbiting tiny stars.
Stars are formedFrom dense clumps of Dust and gas cloudsThis disk is fed into the growing star as water would go down a sink. After the star has formed, what’s left of the disk will become the new star. Turn into planets. Many models Please see below for further information.The amount of material on the disk is The mass of a star can be used to determine the sizeSmaller stars have less material than larger stars.
It is easy to see the direction this is heading. According to our models red dwarfs smaller than around 40 percent the mass and diameter of the Sun should not have enough material to create exoplanets. Yet we Find them.. There are about a dozen of them orbiting tiny stars.
Two separate teams, using two different sets of instruments and almost identical results, discovered and analysed TOI-4860b.
A team led by astronomer José Manuel Almenara of the French National Center for Scientific Research found the exoplanet is 76.6 percent of the radius and 27.3 percent of the mass of JupiterThe Sun is a star that orbits around a mass and radius equal to 34 percent.
A team led Amaury Triaud of University of Birmingham, UK, also discovered TOI 4860b to be 76 percent of Jupiter’s radius but its mass was calculated at 67 %.
There is still some work to be done in order to get an accurate estimate of the mass of the planet. However, the radius is almost identical. This suggests that the exoplanet may be a whopping 22 PercentRadius of its star
What can we do with all this information?
Each team added something new. Almenara, along with his colleagues, found evidence that a second exoplanet, previously unknown, had an orbital period 426.9days and a mass that was at least 1.66times that of Jupiter. This suggests that gravitational interaction between exoplanets could have driven TOI-4860b into its current orbit.
Triaud, his team and their research found that star and exoplanet both have high levels of heavy elements. These findings could give clues to the formation. Researchers caution that the interpretation may not be accurate because it is based on measurements taken in adverse conditions.
But both teams believe that we could learn a lot by conducting further studies. Look into the skyTo find out what it is made of, you can look at TOI 4860b. This might help solve the mystery surrounding these heavyweight worlds.
