CfA Astronomers Find a Black Hole in a Low Mass X-Ray Binary
A team of astronomers from the Harvard-Smithsonian Center for Astrophysics detail the discovery of what might be the first LMXB whose compact object is a…
Astronomers Discover a New Class of Binary Stars
Astronomers from the Harvard-Smithsonian Center for Astrophysics have discovered a new class of binary stars; one star is fully formed while the other is still…
Researchers Reveal New Method for Studying Binary Star Systems
Using data from the Kepler spacecraft, researchers from the University of Washington confirm the first “self-lensing” binary star system. What looked at first like a…
Researchers Model the Workings of an X-ray Binary Star
Using ten years’ worth of optical, infrared and X-ray data on LMC X-3, astronomers developed a model that can successfully explain the workings of an…
Runaway Binary LP 400-22 is Leaving the Galaxy
A new study examines runaway binary LP400-22, providing key insights into runaway stars, white-dwarf binaries, and the complex interactions going on in dense stellar clusters….
Unusual Protostar Periodically Emits Infrared Light Bursts
Using data from the Spitzer Space Telescope, researchers observed an unusual protostar that periodically emits infrared light bursts, becoming 10 times brighter every 25.34 days,…
Red Novae Help Explain the Secret Life of Binary Stars
A newly published study from the University of Alberta examines what happens when binary stars come together in a common envelope, provides a way to…
Short-Period Binary Stars Tend to Merge into Single Star
A computer simulation suggests that there are many single stars that were born as two separate suns, which eventually merged into a single star during…
