  • 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 ...

  • Schella, Jason Walter (Halifax, N.S. : Saint Mary's University, 1991)
    This thesis presents new detailed [superscript 12]CO and [superscript 13]CO observations, using 21" resolution, around the two luminous infrared sources GL 490 and NGC 7538 IRS 9. Observations show strong evidence for ...

  • Majaess, Daniel J. (Halifax, N.S. : Saint Mary's University, 2008)
    We consider the possibility of cluster membership for 13 planetary nebulae that are located in close proximity to open clusters lying in their lines of sight. The short lifetimes and low sample size of intermediate-mass ...

  • 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 ...

  • Lee, Siow Wang (Halifax, N.S. : Saint Mary's University, 1992)
    The high-velocity GL 490 outflow has been observed at high spatial resolution with the JCMT in three rotational transitions (J = 2[right arrow]1 of HBBW = 21", J = 3[right arrow]2 of HPBW = 15" and J = 6[right arrow] 5)of ...

  • Miskolczi, Beverly (Halifax, N.S. : Saint Mary's University, 1998)
    New observations of the molecular cloud NGC 7129, in several emission lines of CO, allows an assessment of the effects of recent and ongoing star formation. The CO data is supplemented with limited HCO[superscript +] J = ...

  • Douglas, Kevin Arthur (Halifax, N.S. : Saint Mary's University, 2000)
    A series of axisymmetric, radiatively cooling variable jets was modeled with the ZEUS3D hydrodynamic code, revealing features commonly seen in outflows from Young Stellar Objects. The jet known as DG Tau B, discovered in ...

  • Morris, Steven L., 1952- (Halifax, N.S. : Saint Mary's University, 1979)
    Differential photometric observations of the three [delta] Scuti stars AI, WZ and XX Sculptoris were obtained on ten nights during October 1978. None of these three stars had been extensively observed before, and the ...

  • Mandushev, Georgi Iliev (Halifax, N.S. : Saint Mary's University, 1994)
    Photoelectric, photographic and CCD photometry, as well as spectroscopic observations and proper motion data for stars in the fields of the short-period galactic Cepheids V1726 Cygni and SU Cygni are presented and analyzed. ...

  • Reed, Laureen G. (Halifax, N.S. : Saint Mary's University, 1986)
    New photoelectric photometry and period searches are presented for three northern delta Scuti variables: LT Vulpeculae, V1208 Aquilae, and 63 Herculis. In past work, two of these three stars were shown to exhibit single-period, ...

  • Funakawa, Hironobu (Halifax, N.S. : Saint Mary's University, 1978)
    Calculations of column densities of some 100 interstellar species based on a steady-state analysis are carried out for interstellar clouds towards [zeta] Oph, [omicron] Per, and Lynds 134, using appropriate cloud models ...

  • Ma, Lifang (Halifax, N.S. : Saint Mary's University, 1994)
    The HH24 complex have been mapped in 12CO J=3-2 emission at 14" resolution, using the 15m James Clerk Maxwell Telescope (JCMT) on Manna Kea, Hawaii. The map in 12CO J=3-2 shows complicated morphology ...

  • Zatzman, Martin E. (Halifax, N.S. : Saint Mary's University, 1976)
    This thesis is the end result of the initial stages of the radio astronomy program at Saint Mary’s University. The main objective of the project was to build a working radio telescope and to test some important properties ...

  • Rohanizadegan, Mina (Halifax, N.S. : Saint Mary's University, 2006)
    The variability of the type C semi-regular (SRC) M3.5 Ia supergiant variable BC Cyg is examined with reference to measurements of its photographic B magnitude derived from 866 archival plates in the Harvard and Sternberg ...

  • Hayes, Jeffrey J. E.(Jeffrey John Edward),1957- (Halifax, N.S. : Saint Mary's University, 1981)
    Photographic and photoelectric photometry are used to obtain intensity profiles of the A1775 double galaxy. The intensity profiles are fitted to the standard (c = 2.25) King models, from which composite models are constructed. ...

  • Shorlin, Stephen Lawrence (Halifax, N.S. : Saint Mary's University, 1998)
    The results of UBV CCD photometry are presented for a newly discovered open cluster, as well as new photometry for thirty-seven members of the open cluster HM 1. The new open cluster, to be designated OCL 1104-610, has a ...

  • Brown, Kevin I.T. (Halifax, N.S. : Saint Mary's University, 2003)
    Stellar non-radial oscillations (p-modes) are ideal tools to test theories of stellar evolution and to provide information about stellar properties. This thesis develops and tests a technique to determine the stellar model ...

  • Takala, John Michael (Halifax, N.S. : Saint Mary's University, 1988)
    This thesis presents a UBV study of the field of the open cluster NGC 7790, which has three Cepheids within its boundaries. Photographic plates taken at CFHT were measured on an Astromechanics Iris Photometer. The distance ...
