Astrophysicists from Northwestern University and the University of California San Diego have identified the tightest binary system ever observed among ultracool dwarfs. The two stars…
By their own admission, Anastasios “Andy” Tzanidakis and James Davenport are interested in unusual stars. The University of Washington astronomers were searching for “stars behaving…
Planetary nebulae are formed when red giant stars reach the end of their helium fuel supply and eject their outer layers, becoming hot and dense…
Researchers say that current measurements of black holes are insufficient to determine the formation process of these invisible giants in the universe. The way a…
A puzzling image captured by the James Webb Telescope explained. A strange image of the distant star WR140 surrounded by concentric geometric ripples captured by…
Astronomers from the Harvard-Smithsonian Center for Astrophysics have concluded from a systematic study of very young cores that most embryonic stars form in multiple systems,…
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 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…
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…
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…
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….
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,…
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…
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…
At the turn of the 19th century, the binary star system Eta Carinae was faint and undistinguished. In the first decades of the century, it…
One hundred and seventy years ago, astronomers thought that a series of explosions on the surface of Eta Carinae (η Carinae) were the beginning of…
These images captured by the Hubble Space Telescope showcase a globular cluster, NGC 6752, a spherical grouping of gravitationally bound celestial bodies that’s over 10…
