Dancing with the (Six) Stars, or, a 200 year story of the Castor system

Dancing with the (Six) Stars, or, a 200 year story of the Castor system

by William Balmer | Nov 7, 2022 | Daily Paper Summaries

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?

Could Stripped Stars be False Positives in the Search for the Missing Black Holes?

by Aldo Panfichi | Oct 3, 2022 | Daily Paper Summaries

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?

Defining Gravity: Can Wide Binaries be a Definitive Test of Modified Newtonian Gravity Theories?

by Aldo Panfichi | Jul 23, 2022 | Daily Paper Summaries

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?

Could Companion Stars Cause Stripped-Envelope Supernovae?

by Sarah Bodansky | May 26, 2022 | Daily Paper Summaries

How do you make a supernova without hydrogen and helium lines? The answer may surprise you! (It’s probably binary stars)

The Case of the Missing Black Hole

The Case of the Missing Black Hole

by Yoni Brande | May 10, 2022 | Daily Paper Summaries

A rare triple system consisting of two stars and a black hole was thought to be in our cosmic backyard. Can new observations from the ESO make the black hole vanish into thin air?

(Mis)alignment Between Exoplanets and Binary Stars

(Mis)alignment Between Exoplanets and Binary Stars

by Konstantin Gerbig | Apr 14, 2022 | Daily Paper Summaries

Binary star systems host exoplanets too! But are planetary orbits aligned or misaligned relative to the stellar companion?
