Not exact matches

Our analysis strongly suggests we are observing a disk of hot gas that surrounds a forming giant planet in orbit around the star.

Just like the GJ436b, these might have been hot Neptunes orbiting around more luminous stars which would have circulated in their atmosphere that ended up leaving the rocky centre of the planet bare.

The planet, known as HD 189733b, is a hot Jupiter, meaning it is similar in size to Jupiter in our solar system but in very close orbit around its star.

Hot Jupiters, exoplanets around the same size as Jupiter that orbit very closely to their stars, often have cloud or haze layers in their atmospheres.

Approximately 650 light - years away, a Jupiter - like planet is caught in an uncomfortably tight orbit around its toasty hot host star.

The main finding is that WASP - 18b, a highly irradiated hot Jupiter in a tight orbit around a hot F - type star, is «wrapped in a smothering stratosphere loaded with carbon monoxide and devoid of water».

Since a star and its planets were never part of a single swirling gas and dust cloud spinning around the same axis, there is no reason for hot Jupiters to have their spin axes aligned with the star's spin axis, or for all their orbits to be prograde.

On March 25, 2015, a team of astronomers using the Hubble Space Telescope revealed observations which indicate via the transit method that Alpha Centauri B may have a second planet «c» in a hot inner orbit, just outside planet candidate «b.» After observing Alpha Centauri B in 2013 and 2014 for a total of 40 hours, the team failed to detect any transits involving planet b (previously detected using the radial velocity variations method and recently determined not to be observed edge - on in a transit orbit around Star B).

The new exoplanet, dubbed «HIP 116454b,» is 2.5 times the diameter of Earth and follows a close, nine - day orbit around its parent star, whose small size and cool temperature make the planet too hot to support life.

KELT - 9, the star around which this new planet orbits, is more than twice as large and nearly twice as hot as our sun, explained co-lead author and Vanderbilt physics and astronomy professor Keivan Stassun.

The planet, dubbed WASP - 18b, has a mass about 10 times that of Jupiter and completes one orbit around its star WASP - 18 in less than 23 hours, which places the planet in the «hot Jupiter» category of exoplanets, or planets that are located outside our solar system.

Astronomers from Wesleyan University have detected the shock waves produced by a high - speed «hot Jupiter» exoplanet caught in a tight orbit around its host star.

The smallest planet orbits Kepler - 33, a star older and more massive than our Sun, Sol, which also had the most detected planet candidates at five (ranging in size from 1.5 to 5 times that of Earth) in uninhabitable, hot inner orbits closer to their star than even Mercury around our Sun (NASA Kepler news release; and JPL news release).

With a semi-major axis of 0.066 AUs, it orbits so close to its host star that its orbital period lasts only 8.78 days, and so the planet must be very hot at around 450 ° Kelvin, 351 ° F, or 177 ° C (Forveille et al 2008).

The first exoplanet to burst upon the world stage was 51 Pegasi b, a hot Jupiter 50 light - years away that is locked in a four - day orbit around its star.
