Astronomers led by Teruyuki Hirano report discovery of a new exoplanet similar in size to Earth around nearby star K2-415. With only 16 % solar mass the small red dwarf is one of the smallest stars known to host exoplanets.
Binary star TOI 1338 has at least two exoplanets orbiting it. Astronomers led by Matthew Standing discovered the second one using radial velocity method and data from observatories La Silla and VLT. Exoplanet TOI 1338 c is the first one detected solely by the radial velocity method and the system TOI 1338 is now the second known to have multiple exoplanets orbiting more than one star.
Astronomers used the James Webb Space Telescope (JWST) to peer into the young planetary system around AU Microscopii. The pre-main sequence red dwarf star is only 32 light years away which makes it one of the closest ones. There are 2 known exoplanets and a disc of dust orbiting it.
Astronomers found a brown dwarf in orbit of a bright B-type star HIP 33609. The host star has a radius 2.5 times bigger than the Sun and surface temperature above 10 000 °C. The newly found brown dwarf has about 7 % of the Sun's mass and about 16 % of its radius.
