AzV 493 and its Variable Dance
In today’s paper, learn about the strange behavior of a variable star, and a possible explanation for its strange behavior: an invisible dancing partner!
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.
Dancing with the (Six) Stars, or, a 200 year story of the Castor system
Astronomers study the orbits of a sextuplet system, an absurdly complex arrangement of six stars in orbit around one another, in order to measure their masses once and for all.
Could Stripped Stars be False Positives in the Search for the Missing Black Holes?
The authors of today’s article argue that stripped B-type stars could be a source of false positives in the search for quiet, stellar-mass black holes in the Milky Way
Defining Gravity: Can Wide Binaries be a Definitive Test of Modified Newtonian Gravity Theories?
Today’s paper posits that precise observations of wide binaries can be used, in conjunction with simulations, to test the validity of modified gravity theories!
Could Companion Stars Cause Stripped-Envelope Supernovae?
How do you make a supernova without hydrogen and helium lines? The answer may surprise you! (It’s probably binary stars)
