The astronomer announced at an online conference during the 236th annual meeting of the American Astronomical Society (AAD) that he had analyzed archive footage from the Hubble telescope from two decades ago.
"When we studied Proxima Centauri in the mid-1990s, we were looking for planets located relatively close to the star, where the year equals no more than a thousand Earth days. With the help of archival footage, we checked whether there were more distant worlds around the star,” Benedict said at the conference, as quoted by the press office of AAD. The astronomer is a leading research fellow at the University of Texas at Austin.
Four years ago, European astronomers announced that they had managed to discover around Proxima Centauri a small Earth-like planet.
Proxima Centauri is a red dwarf from the triple Alpha Centauri system. The planet was named Proxima Bae, and its existence was confirmed a year ago by its discoverers, who came across data that another planet was hovering around the star - Proxima Tse. It is further distant from the star and is a gas giant, on which the year lasts almost two thousand earth days. This hypothesis has been sceptically accepted by many planetologists, especially since no credible confirmation of Proxima Tse's existence has been found in the last four years.
According to Benedict and his colleague Barbara MacArthur, Proxima Tse's mass is about seven times that of Earth. This refers Proxima Tse to the so-called minineptunes, which line between the big stony planets and the gas giants.
American astronomer: Two planets circle around Proxima Centauri
American astronomer Fritz Benedict has found new evidence that around Proxima Centauri, the closest star to us after the Sun, is circling two planets, TASS and BTA reported.tags:
