Spectral–Timing Analysis Of Kilohertz Quasi–Periodic Oscillations In Neutron Star Low Mass X-Ray Binaries, Jon Troyer
Wayne State University Dissertations
Kilohertz quasi-periodic oscillations or kHz QPOs are X-ray intensity variations observed
in neutron star low-mass X-ray binary (LMXB) systems. In such systems, matter is transferred
from a secondary low-mass star to a neutron star via the process of accretion. kHz
QPOs occur on the timescale of the inner accretion flow and may carry signatures of the
physics of strong gravity (c2 ~GM/R) and possibly clues to constraining the neutron star
equation of state (EOS). No model to date has been able to illuminate the origin of kHz
QPOs. Spectral-timing is a set of analysis techniques useful in deriving information about …
