Neutron stars provide the key to understanding the equation of state at the highest pressure and density. Constraining the mass-radius relation of neu- tron stars will provide opportunities to test the currently conflicting candidates for the equation of state. Next generation instruments, such...

Neutron stars (NSs) are some of the densest objects in the universe. In this thesis, I focus on studying X-ray thermal emission from neutron stars, using X-ray observations of different varieties of NSs. X-ray observations can put constraints on the mass and radius of NSs, and thus on density and...

Star formation drives secular galaxy evolution by linking stars and gas in galaxies. This link forms part of the "baryonic cycle," where stars form from interstellar gas, and a portion of that gas is returned to the interstellar medium upon the star’s death. Understanding the baryonic cycle and...

A young neutron star cools mainly via neutrino emission from the star's core. Thus, the thermal evolution of neutron stars reflects changes in their core, constraining temperature-sensitive properties such as the composition of the core and the envelope of the neutron star. The neutron star in...

The equation of state for cold ultra-dense matter has puzzled astrophysicists for decades. This is because the conditions of supra-nuclear density matter, such as those in neutron stars, are not terrestrially replicable. X-ray light curves from accreting neutron stars have proven to be useful...

In this thesis we study X-ray millisecond pulsars (MSPs) in the Galactic globular clusters (GCs) to better understand the X-ray emission from them. We analyze 55 ks and 290 ks of Chandra X-ray observations of the clusters M13 and Omega Cen, respectively. We find confident X-ray counterparts to...
