Investigating the mystery of migrating 'hot Jupiters'

The last decade has seen a bonanza of exoplanet discoveries. Nearly 2,000 exoplanets—planets outside our solar system—have been confirmed so far, and more than 5,000 candidate exoplanets have been identified. Many of ...

Astronomers discover two new 'hot Jupiter' exoplanets

(Phys.org)—A team of Chilean astronomers recently detected two new "hot Jupiters" using the data from NASA's Kepler spacecraft operating in a new mission profile called K2. The planets, designated EPIC210957318b and EPIC212110888b, ...

'Hot Jupiters' provoke their own host suns to wobble

Blame the "hot Jupiters." These large, gaseous exoplanets (planets outside our solar system) can make their suns wobble when they wend their way through their own solar systems to snuggle up against their suns, according ...

Astronomers see misaligned planets in distant system

Using data from NASA's Kepler space telescope, an international team of astronomers has discovered a distant planetary system featuring multiple planets orbiting at a severe tilt to their host star.

First planets found around sun-like stars in a cluster

(Phys.org)—NASA-funded astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster of stars. The findings offer the best evidence yet planets can sprout up in dense stellar environments. ...

Super-Earth has an atmosphere, but is it steamy or gassy?

In December 2009, astronomers announced the discovery of a super-Earth known as GJ 1214b. At the time, they reported signs that the newfound world likely had a thick, gaseous atmosphere. Now, a team led by Jacob Bean (Harvard-Smithsonian ...

Early exit for hot Jupiter due to deadly tides

(PhysOrg.com) -- Bad news for planet hunters: most of the "hot Jupiters" that astronomers have been searching for in star clusters were likely destroyed long ago by their stars. In a paper accepted for publication by the ...
