The accretion instability of black holes and neutron stars has something in common
The Milky Way’s central black hole, Sagittarius A*, is a fast-moving supermassive black hole, which is nearly four times more massive than the Sun, scientists have claimed. The model estimates how quickly matter is falling on the black hole from the brightness of the bagels of light. They also suggest that X-ray eclipses constrain the…

A red-superGiant supernova cooling at a redshift 3
Astronomers have discovered a “dynamically driven” Type Ia supernova explosion in our Milky Way. The Supernovae was observed to be nearly three times as bright as previous Type Ia supernovas. This supernova explosion is associated with “dynamically-driven” Double Degenerate Double Detonations, coined by Ken Shen, an astrophysicist at University of California, Berkeley, in his book…
