Low-luminosity x-ray sources

My research group will use X-ray telescopes to study the behavior of the dense remnants of dead stars. These remnants, including neutron stars (more massive as the Sun, but the size of a city) and white dwarfs (as massive as the Sun, but the size of the Earth) are sometimes located in binary systems, paired with a normal star. We will study the X-rays generated as the remnants' strong gravity pulls material off the normal stars and down onto their surfaces. Studying X-rays from the surface of neutron stars can also provide hints to the interior composition of the neutron stars, revealing whether more exotic particles congregate in their cores.
