Of the more than 4,500 stars known to have planets, one puzzling statistic stands out. Even though nearly all stars are expected to have planets and most stars form in […]
Circumbinary.

Rare Image Of Tatooine-like Planet Is Closest To Its Twin Stars Yet
In a discovery that’s fit for a movie, Northwestern University astronomers have directly imaged a Tatooine-like exoplanet, orbiting two suns.

Revising Properties of Planet-Host Binary Systems. IV. The Radius Distribution of Small Planets in Binary Star Systems is Dependent on Stellar Separation
Small planets (Rp≤4R⊕) are divided into rocky super-Earths and gaseous sub-Neptunes separated by a radius gap, but the mechanisms that produce these distinct planet populations remain unclear.

BEBOP V. Homogeneous Stellar Analysis of Potential Circumbinary Planet Hosts
Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed view into our understanding of circumbinary […]

On The Properties Of Free Floating Planets Originating In Circumbinary Planetary Systems
Free-floating planets are a new class of planets recently discovered. These planets don’t orbit within stellar systems, instead living a nomadic life within the galaxy.

Thermal Structure Of Circumbinary Discs: Circumbinary Planets Should Be Icy Not Rocky
The process of forming a circumbinary planet is thought to be intimately related to the structure of the nascent circumbinary disc. It has been shown that the structure of a […]
