Constraining the Physics of the X-ray Irradiated Accretion Discs in Low-mass X-ray Binaries with Observations
DownloadFall 2018
Recurring outbursts associated with matter flowing onto compact stellar remnants (black holes and neutron stars) in low-mass X-ray binary systems provide constraints on the poorly understood accretion process. Multi-wavelength light-curves and spectra of these bright outbursts provide powerful...

Neutron stars are some of the densest objects in the Universe, with densities in their cores that are larger than that of the atomic nucleus. Their relatively small size allows them to spin very rapidly, with speeds at the equator that are a large fraction of the speed of light. Being some of the...

Neutron stars are interesting due to their extremely large densities (∼ 1015 g/cm^3), and also because the accretion of matter from a companion star can spin them up to very high frequencies (∼716 Hz based on observations ). When we study black holes (BH), the only thing that we have to worry...

We examine the long-term evolution of accretion tori around the remnants of compact object mergers and the explosions of highly magnetized massive stars to better understand their roles in the creation of optical transients and the synthesis of r-process elements. We begin by modifying the...
