What do you call two stars hurtling around each other with bursts of X-rays every few decades? An X-ray transient, of course! This special flavor of X-ray binary features a neutron star or black hole together with a low-mass star.
Short gamma-ray bursts, extremely energetic explosions in the Universe, might be caused by the merger of two compact objects. In the two papers we discuss today, the authors test this scenario by looking for light emitted still a few days after the explosion.
A massive white dwarf accreting from a companion can lead to accretion induced collapse turning the white dwarf into a neutron star – how can such an event be observed?
What happens when a neutron star collapses into a black hole? What kind of signal could we expect to see? These theorists have some ideas…
This month’s undergrad research post is all about X-rays. Read on to learn more about studying the X-ray counterpart to a radio pulsar, and examining the evolution of galaxies using X-ray emission.
What happens to neutrons in the extreme environment found in a neutron star? According to these authors, they could deform to become cubes!
