Comptonization and QPO Origins in Accreting Neutron Star Systems
Hyong C. Lee, Guy S. Miller
We develop a simple, time-dependent Comptonization model to probe the origins of spectral variability in accreting neutron star systems. In the model, soft ``seed photons'' are inj…

Variability and Stability in Radiation Hydrodynamic Accretion Flows
Guy S. Miller, Myeong-Gu Park
In this paper we examine time-dependent and three-dimensional perturbations of spherical accretion flow onto a neutron star close to its Eddington limit. Our treatment assumes a Sc…

X-Ray Spectra of Z Sources
Dimitrios Psaltis, Frederick K. Lamb, Guy S. Miller
A simple, physically consistent model has been proposed that seeks to explain in a unified way the X-ray spectra and rapid X-ray variability of the so-called Z sources and other ac…
