What our solar system was probably like a long time ago — Discovering a debris disk around BD+45°598
Today’s astrobite discusses how an edge-on debris disk was discovered and modeled, and what sort of planets might be found there!
Could some Earthlings survive in exoplanets around M-dwarfs?
Today’s post tells you whether cyanobacteria, a type of bacteria that can do photosynthesis, could survive in an exoplanet orbiting M-dwarfs (which are cool, red stars)!
The Kozai-Lidov Tango: The Ups and Downs of being a Polar Circumbinary Disk
Can binary stars have circumbinary disks that orbits them in a perpendicular plane? Today’s authors took a closer look at this setup and the complex exchange of material between stars and circumbinary disk.
Are Hot Jupiters Lonely?
A new study finds that Hot Jupiters have companion planets in the system at a higher rate than previously thought. This has big implications for the theories on how these fascinating planets, and their larger systems, form.
Movement in the Dust: Detecting Planetary Candidates via Disk Kinematics?
In today’s paper, the authors analyze millimeter and submillimeter ALMA observations of a protoplanetary disk, and find kinematic signs of candidate companions within!
Newly discovered planet AF Lep is leading its star astray
Direct imaging exoplanets is difficult, but a new method of vetting targets has just helped three independent teams discover, and image, a new gas giant.
