X-ray bursts are driven by the thermonuclear runaway on the surface of an accreting neutron star [4,131,159]. The runaway is triggered by the triple process and the break-out reactions from the hot CNO cycles which cause the feeding of the rp-process [18,121].

What causes gamma-ray bursts quizlet?
What causes gamma ray bursts? -Gamma ray bursts occur is distant galaxies but they shine so brightly in the sky that they must be the most powerful explosions we have ever seen. -Gamma ray bursts appear to come from unusually powerful supernova.
What is the origin of short gamma-ray bursts quizlet?
What is the origin of short gamma ray bursts? It is not known but it may be the collision of a neutron star with a black hole.
What causes an X-ray burster to form?
For an X-ray burst, the compact object is a neutron star which accretes a surface layer of helium that undergoes explosive burning to produce the outburst. For recurrent novae, the compact object is a white dwarf which accretes a surface layer of hydrogen that undergoes explosive burning to produce the outburst.

What is the origin of short gamma-ray burst quizlet?
What is the origin of short gamma ray bursts? It is not known but it may be the collision of a neutron star with a black hole.
What is the leading hypothesis for the origin of short gamma-ray bursts?
Currently, the leading hypothesis for the origin of the "short" kind of these gamma-ray bursts is the merger of a neutron star with either a black hole or another neutron star.
What causes X-ray bursts quizlet?
The source of the X-rays from X-ray bursters has been associated with neutron stars in mass transfer binary systems. As in the case of a white dwarf in a binary system, material transferred from the companion forms an accretion disk around the neutron star leading to the accumulation of gas on its surface.
Death From Space — Gamma-Ray Bursts Explained
What are the two causes of a gamma-ray burst?
One explanation proposes that they are the result of colliding neutron stars -- corpses of massive stars (5 to 10 times the mass of our Sun) that have blown up as supernovae. A second theory proposes that gamma-ray bursts are the result of a merging between a neutron star and a black hole or between two black holes.
What may be responsible for the observed gamma ray bursters?
A class of Neutron stars that have exceedingly strong magnetic fields. These are believed to emit short gamma ray bursts. This occurs when shifts in the magnetic field of the magnetar breaks the crust of the neutron star. When this occurs, large amounts of energy are released.

What causes gamma ray burst?
Scientists now know that the vast majority of gamma-ray bursts are "long bursts"longer than 2 seconds. They are thought to occur when a massive star runs out of fuel. Without a force to resist the crush of its own gravity, the core of the star collapses into a black hole.
What causes long gamma burst?
Ultra-long gamma-ray bursts They have been proposed to form a separate class, caused by the collapse of a blue supergiant star, a tidal disruption event or a new-born magnetar.
