K2-25: An eccentric hot Neptune with the mass of seven Earths

Of the roughly 4,300 exoplanets confirmed to date, about ten percent of them are classified as "hot Jupiters." These are planets with masses between about 0.4 and 12 Jupiter-masses and orbital periods less than about 110 ...

New study reveals mystery of decaying exoplanet orbits

A new study led by researchers at Durham University has uncovered a novel mechanism that could solve a long-standing mystery about decaying planetary orbits around stars like our sun.

Is this how you get hot Jupiters?

When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar ...
