Also, what evidence would point to this? Specifically, they have found that 51 Peg b’s atmosphere is 0.01% water – a sizeable proportion – and that it orbits its star at 133 km/s and weighs 0.476-times as much as Jupiter (give or take 7%). Beneath this, the gases that make up the planet would be so hot that the planet would glow red. 51 Pegasi b probably has a greater radius than that of Jupiter despite its lower mass. 51 Pegasi b (abbreviated 51 Peg b), sometimes unofficially named Bellerophon, is an extrasolar planet approximately 50 light-years away in the constellation of Pegasus. In the limit of a nearly isothermal dayside atmosphere, as seems to be the case for some hot Jupiters (see, e.g., Crossfield et al. Their results were uploaded to the arXiv preprint server on January 25. Scientists spotted water in the atmosphere of 51 Pegasi b, one of the first exoplanets ever been discovered. 51 Pegasi b was the first planet to be discovered orbiting a main-sequence star, the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research. Favourite answer. Evidence for a spectroscopic direct detection of reflected light from 51 Pegasi b 2015 MARTINS J., SANTOS N., FIGUEIRA P., FARIA J., MONTALTO M. et al. It is the prototype for a new and previously unsuspected class of planet known as epistellar Jovians, or "hot Jupiters," with remarkably small orbits. Beneath this, the gases that make up the planet would be so hot that the planet would glow red. 51 Pegasi b was the first, but now we know thousands of exoplanets. 51 Pegasi b on tähteä 51 Pegasi kiertävä eksoplaneetta.Se on ensimmäinen Aurinkokunnan ulkopuolelta löydetty auringonkaltaisen tähden kiertolainen. 51 Pegasi is a yellow-orange main sequence dwarf star of spectral and luminosity type G4-5 Va, but it had been previously classified as G2-2.5 and sometimes as a subgiant (IV). Talk:51 Pegasi B : 51 Pegasi B → Bellerophon (planet) — because Bellerophon is the common name, and the one the press uses. 84 relations. 1 decade ago. At half of Jupiter's mass and way over Saturn's mass, 51 Pegasi b would be most likely a gas giant.
