(American Astronomical Society, 2008-08)Spectral energy distributions for models of arbitrarily rotating stars are computed using two-dimensional rotating stellar models, NLTE plane-parallel model atmospheres, and a code to integrate the appropriately weighted ...
-
(American Astronomical SocietyIOP Publishing, 2009-03-01)We have investigated the effects of uniform rotation and a specific model for differential rotation on the pulsation frequencies of 10 M[subscript circled dot] stellar models. Uniform rotation decreases the frequencies for ...
-
(American Astronomical Society, 2012-07)Spectral energy distributions are computed using two-dimensional (2D) rotating stellar models and non-LTE plane-parallel model atmospheres. A rotating, 2D stellar model has been found that matches the observed ultraviolet ...
-
(American Astronomical SocietyIOP Publishing, 2008-06-01)We use two-dimensional stellar models and a two-dimensional finite difference integration of the linearized pulsation equations to calculate nonradial oscillations. This approach allows us to directly calculate the pulsation ...
-
(American Astronomical Society, 2011-04)We are developing a three-dimensional radiation hydrodynamics code to simulate the interaction of convection and pulsation in classical variable stars. One key goal is the ability to carry these simulations to full amplitude ...

(American Astronomical SocietyIOP Science, 2013-07-10)We have developed a three-dimensional radiation hydrodynamics code to simulate the interaction of convection and radial pulsation in classical variable stars. One key goal is the ability to carry these simulations to full ...
-
(American Physical Society, 2014-03-10)We have developed a multi-dimensional radiation hydrodynamics code to simulate the interaction of radial stellar pulsation and convection for full-amplitude pulsating models. Convection is computed using large eddy ...
-
(American Astronomical Society, 2015-02-10)Three-dimensional hydrodynamic simulations of full amplitude RR Lyrae stars have been computed for several models across the instability strip. The three-dimensional nature of the calculations allows convection to be treated ...
-
(The American Astronomical Society, 2014-10-10)The spectral energy distribution as a function of inclination is computed using two-dimensional rotating stellar models and NLTE plane parallel stellar atmospheres. These models cover the range from 1.875M☉ to ...
-
(American Astronomical Society, 2005-11)The structure and evolution of close binary stars has been studied using the two-dimensional stellar structure algorithm developed by Deupree. We have calculated a series of solar composition stellar evolution sequences ...
-
(IOP Publishing Limited, 2011-07-10)Zero-age main-sequence models of uniformly rotating stars have been computed for 10 masses between 1.625 and 8 M☉ and for 21 rotation rates from zero to nearly critical rotation. The surface shape is used to ...
-
(American Astronomical SocietyIOP Publishing, 2006-05-20)Extreme deformation of a stellar surface, such as that produced by rapid rotation, causes the surface temperature and gravity to vary significantly with latitude. Thus, the spectral energy distribution (SED) of a nonspherical ...
-
(IOP Publishing Limited, 2011-11-20)A rotating, two-dimensional stellar model is evolved to match the approximate conditions of α Oph. Both axisymmetric and nonaxisymmetric oscillation frequencies are computed for two-dimensional rotating models which ...
