Astronomers have recently confirmed the existence of the exoplanet TOI-4465 b, which spins around in a pretty wide orbit.. Its transits are quite difficult to observe. Scientists were assisted in this by amateurs from all over the world.
Confirmation of an exoplanet’s existence
Scientists have confirmed the existence of the exoplanet TOI-4465 b with the help of a network of amateurs who tracked its transit across the star’s disk. This is described in an article published in The Astronomical Journal.
TOI-4465 b is a gas giant located 400 light-years from Earth. It was discovered by the TESS (Transiting Exoplanet Survey Satellite) space telescope. However, it should be understood that this discovery is only a single transit, i.e., an eclipse of the star by a planet passing between us and it, and several more need to be observed to confirm that there really is something there.
Unfortunately, in the case of TOI-4465 b, it is not so simple. The planet’s rotation period is 102 days, and the transit lasts 12 hours. Finding so much free time for astronomical instruments that are always busy is a very difficult task.
Features of TOI-4465 b
TOI-4465 b is a gas giant exoplanet with a radius approximately 25% larger than Jupiter’s, a mass nearly six times greater than Jupiter’s, and a density nearly three times greater. The planet has a slightly elliptical orbit, resulting in a temperature range of 375-478 K (approximately 200-400 °F).
New World is a rare example of a giant planet that is large, massive, dense, and temperate, covering a relatively unexplored area in terms of planetary size and mass.
All this makes it a good candidate for future atmospheric research using telescopes such as the James Webb Space Telescope (JWST). It is among the best exoplanets with long rotation periods available for study using emission spectroscopy, which can reveal key details about its atmosphere.
