Quoted from Live science, Sunday (May 12th, 2021) this newly discovered exoplanet belongs to the hot Jupiter category. Although astronomers have identified more than 400 hot Jupiters to date, none resemble the planet TOI-2109b.
“Everything was consistent, it was a planet, and we discovered that we have something very interesting and relatively rare,” said Avi Shporer, an exoplanet scientist at the Massachusetts Institute of Technology (MIT).
Shporer and his colleagues incorporated their results into data collected by NASA’s Transiting Exoplanet Survey Satellite (TESS), which has orbited Earth since April 2018.
TESS has improved its search ability Planet orbiting its star very quickly, as telescopes typically monitor a strip of the sky for about a month before moving.
In the case of TOI-2109b, the planet orbits every 16 hours, faster than other planetary scientists have found. The planet’s star is located about 855 light-years from Earth in the constellation Hercules. After seeing the signal, they used another telescope to examine a star called TOI-2109.
“Since the beginning of exoplanet research, hot Jupiters have been viewed as strange objects. How a planet the size of Jupiter enters an orbit that lasts only a few days. We see this as an opportunity to study them and explain their existence, ”he said.
