A classification atlas of stellar spectra of luminosity types III and V for the Burke-Gaffney Observatory

Bailey, Robert G. (Halifax, N.S. : Saint Mary's University, 1978)

The MK classification system is defined by the spectra of an array of standard stars and is based on the appearances and relative intensities of selected spectral lines, blends, and bands observed in the blue-violet region ...
A high resolution M band study of W3 IRS5

Belcourt, Kenneth Noel (Halifax, N.S. : Saint Mary's University, 1989)

This thesis presents an infrared spectral analysis of the high mass protostar W3 IRS5. A high resolution M band spectrum of W3 IRS5 was obtained from the CFHT with the Fourier Transform Spectrometer. The spectrum was ...
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 ...
NLTE 1.5D modelling of red giant stars

Young, Mitchell (Halifax, N.S. : Saint Mary's University, 2013)

Spectra for 2D stars in the 1.5D approximation are created from synthetic spectra of 1D non-local thermodynamic equilibrium (NLTE) model atmospheres produced by the PHOENIX code. The 1.5D stars assume the spatially averaged ...
