Can I Have This Dance?
Join the dance of binaries and triplets swaying their protoplanetary dresses in today’s bite!
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!
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.
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!
A Potential New Character in the Saga of HD 163296
An extra protoplanet might be lurking in the dust around a nearby star
History lessons from chemical elements
Chemical elements are pretty good history teachers! Today’s paper describes how chemical abundances can tell us about the history of where a planet formed.
