The effects of differential rotation on the spectral energy distribution and line profiles of the rapidly rotating star alpha Oph

Castañeda, Diego (Halifax, N.S. : Saint Mary's University, 2012)

The spectrum of the rapidly rotating star [alpha] Oph was modeled to examine the effect differential rotation has on its observed SED. Rotating stellar structure models were generated using the code ROTORC and constrained ...
Matching the spectral energy distribution and p-mode oscillation frequencies of the rapidly rotating delta Scuti star [alpha] Ophiuchi with a two-dimensional rotating stellar model

Deupree, Robert G. (Robert Gaston), 1946-; Castañeda, Diego; Pena, Fernando; Short, C. Ian (Christopher Ian), 1965- (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 ...
Properties of rapidly rotating stars and their oscillation modes

Castañeda, Diego (Halifax, N.S. : Saint Mary's University, 2016)

In this thesis I present a set of scaling relationships for ZAMS rotating models. These relationships are applicable to models whose rotation rate produces a given surface distortion and are shown to be valid for stellar ...
