Short-N characteristic radiative transfer method in 2D cylindrical RZ coordinates
Nicolas A. Pereyra, Joseph J. MacFarlane, Pamela R. Woodruff +2
We present a new radiative transfer method Short-N Characteristics that is a hybrid between the standard long characteristic methods and the standard short characteristic methods.…
Characteristic QSO Accretion Disk Temperatures from Spectroscopic Continuum Variability
Nicolas A. Pereyra, Daniel E. Vanden Berk, David A. Turnshek +5
Using Sloan Digital Sky Survey (SDSS) quasar spectra taken at multiple epochs, we find that the composite flux density differences in the rest frame wavelength range 1300-6000 AA c…
On the Steady Nature of Line-Driven Disk Winds: Application to Cataclysmic Variables
Nicolas A. Pereyra, David A. Turnshek, D. John Hillier
We apply the semi-analytical analysis of the steady nature of line-driven winds presented in two earlier papers to disk winds driven by the flux distribution of a standard Shakura…
Further Criteria for the Existence of Steady Line-Driven Winds
N. A. Pereyra
In Paper I, we showed that steady line-driven disk wind solutions can exist by using "simple" models that mimic the disk environment. Here I extend the concepts introduced in Paper…
Hydrodynamic Models of Line-Driven Accretion Disk Winds III: Local Ionization Equilibrium
Nicolas A. Pereyra, Timothy R. Kallman
We present time-dependent numerical hydrodynamic models of line-driven accretion disk winds in cataclysmic variable systems and calculate wind mass-loss rates and terminal velociti…
Hydrodynamic Models of Line-Driven Accretion Disk Winds II: Adiabatic Winds from Nonisothermal Disks
Nicolas Antonio Pereyra, Timothy R. Kallman, John M. Blondin
We present here numerical hydrodynamic simulations of line-driven accretion disk winds in cataclysmic variable systems. We calculate wind mass-loss rate, terminal velocities, and l…
