What was once thought to be one brown dwarf was revealed last year to be two brown dwarfs, and new work suggests that these two objects have masses of 37.7 and 34.4 Jupiter masses and a 12-day orbit.
Sensitive X-ray polarization measurements from the Imaging X-ray Polarimetry Explorer challenge the idea that black hole accretion flows typically have large-scale, strong magnetic fields.
A newly developed algorithm allows for a less computationally intensive treatment of globular clusters being stretched into thin stellar streams, achieving 10% accuracy.
Researchers investigate the mysteries of Loki Patera, a lava lake on Jupiter’s moon Io that displays islands in persistent locations for at least the past 45 years and lacks certain features that other lava lakes share.
Modeling shows that a theory-defying black hole could have formed through the evolution of a triple-star system containing stars with initial masses of 1.49, 1.05, and 21.81 solar masses.
Accounting for relativistic effects and thermal electrons dramatically alters the derived parameters of high-velocity shocks, recent research shows.
