Abstract:
Neutron stars are born in the aftermath of supernova stellar explosions. They contain the mass of one or two suns compressed within only ten kilometres, resulting in gravitational fields so strong that general relativistic effects become significant in their vicinity, affecting spacetime and the propagation of light near their surface. Due to their extreme compactness, the densities inside neutron stars reach values unattainable on Earth. Their matter may exist in superfluid and superconducting states, and free quarks may even appear in their cores.
When neutron stars orbit a companion star, they can accrete matter from the outer layers of the companion. This newly acquired matter may burn unstably on the neutron star surface, producing bright X-ray flashes known as Type I bursts.
In this talk, I will show how modelling the burning processes during Type I bursts provides insight into the physics of neutron stars, including their internal composition and magnetic fields, as well as into nuclear reactions and the binary systems in which the bursts occur, such as accretion processes.
The speaker will deliver the talk in person.
Everybody is welcome to join either onsite in room 203 or via Zoom.
