The International Astron group announced that two outer planets revolving around the HD 35843 stars in 260 light years from the ground. The finding was made using TESS space telescope and approved with ground observations. The study was published at the following address Portal Expected scientific materials Arxiv.
The central star of the system is a yellow dwarf with a sun -like, but low metal content. It is estimated that the age is 2.5 billion years – almost half of our armature.
The first planet is classified as a super place, HD 35843 B. It is 5.8 times larger than our planet and creates a complete revolution around the star in just 9.9 days. The second planet is particularly interesting for scientists HD 35843 C. It is 2.5 times larger and 11.3 times larger than Earth and makes a return for 46.7 days.
“This is one of the coldest worlds discovered by TESS, which has a balance temperature of approximately 206 ° C,” he said.
Scientists cannot correctly determine the nature of HD 35843 C. Possible options include a water world with a global ocean, a rocky planet with an intense atmosphere, or an intermediate class between Super -Maryth and Neptunes.
Previously, researchers learnedThese planets can “play” millions of years after the asteroid strike.
