Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. [6]
Data from the Transiting Exoplanet Survey Satellite was analysed by the astronomer Madyson Barber and colleagues, allowing the planet detection. After rulling out alternative explanations for the observed transit, the team was able to confirm its existence. Its discovery and confirmation was published on November 20, 2024, in the journal Nature ...
The first planetary transit observed (by already known exoplanet) was caused by HD 209458 b. The most massive transiting exoplanet is KELT-1b which masses 27.23 M J (making it a brown dwarf) while the least massive is Kepler-42d which masses less than 0.003 M J or 0.9 M E. [2] The largest exoplanet known is HAT-P-32b which is 2.037 R J.
The first exoplanet for which transits were observed for HD 209458 b, which was discovered using radial velocity technique. These transits were observed in 1999 by two teams led David Charbonneau and Gregory W. Henry. [19] [20] [21] The first exoplanet to be discovered with the transit method was OGLE-TR-56b in 2002 by the OGLE project. [22 ...
In January 2021, a team led by Lauren Weiss of the University of Hawaii at Manoa announced that, using data from NASA's Transiting Exoplanet Survey Satellite, they had found a Super-Earth in a very close orbit, as well as two outer Sub-Neptunes. [7] [8] [6] [3] The innermost planet, TOI-561 b, orbits in under one Earth day.
TOI-2180 b is a giant exoplanet orbiting the G-type star TOI-2180, also known as HD 238894. [1] It was discovered with the help of the Transiting Exoplanet Survey Satellite and is currently the exoplanet with the longest orbital period TESS was able to uncover (as of September 2022). [3] TOI-2180 b orbits its host star every 260.16 days. [2]
Gliese 341 b was first identified in observations by the Transiting Exoplanet Survey Satellite (TESS) as a candidate planet yet to be confirmed. [3] Its confirmation was first announced by a group of astronomers led by James Kirk, along with a transmission spectrum by the James Webb Space Telescope.
The white dwarf is known to host one exoplanet, WD 1856+534 b, in orbit around it.The exoplanet was detected through the transit method by the Transiting Exoplanet Survey Satellite (TESS) between July and August 2019.
