Physics behind unusual behavior of stars’ super flares discovered

Researchers at Syracuse University found that stellar spin can explain the fading of black hole flares in repeating partial tidal disruption events. The study suggests that stars with rapid initial spin may produce flares that decline in brightness over time. This new understanding provides insight into the complex interactions between...

Researchers have cataloged nearly 1400 slow-rising flares using Chandrayaan-2 data, revealing a significant increase in the number of slow-building flares compared to previous decades. The study suggests that solar flares may exhibit different behaviors, including varying rates of rise and fall.

Astronomers have uncovered 21 neutron stars in wide orbits around stars like our Sun, revealing the first dark neutron star population. The discovery was made possible by the European Space Agency's Gaia mission, which scanned the sky and measured wobbles of over a billion stars.

Scientists have identified flickering loops in the solar atmosphere that signal impending solar flares. The loops' brightness variability can be measured to predict flares with up to 80% accuracy, potentially providing 2-6 hours of warning time for astronauts and technology.

Astronomers uncover evidence of a massive star's quiet demise into a black hole without a supernova explosion. The VFTS 243 system shows minimal signs of an explosion, offering insight into stellar evolution and collapse theories.

Astronomers have discovered entwined dwarf stars emitting radio pulses, challenging the long-held assumption that only neutron stars were responsible for these emissions. The discovery was made using follow-up observations of two stars orbiting each other every two hours.
