-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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, ...
-
(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 ...
-
(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 ...
-
(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. ...
-
(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 ...
-
(Halifax, N.S. : Saint Mary's University, 1987)In continuation of a search for long-period [P>10d] Cepheids embedded in associations (van den Bergh et al. 1982, 1983, 1984) U, B and V plates centered on the 13.2d Cepheid GT Carinae, and including the Cepheid U Carinae ...

(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 ...
-
(Halifax, N.S. : Saint Mary's University, 1979)Bahcall (1975) has found that the average core radius for a group of 15 clusters of galaxies is 0.25[plus or minus]0.05 Mpc. At the suggestion of Dr. G. Welch it was decided to study four nearby clusters of galaxies (A2052, ...
-
(Halifax, N.S. : Saint Mary's University, 1990)This thesis presents independently calibrated CCD surface photometry derived from 12 images of the shell galaxy NGC 2865 in the B, V, and R passbands. Short exposures were used to permit accurate sky subtraction. Mean ...
-
(Halifax, N.S. : Saint Mary's University, 1985)A systematic procedure for processing and reducing CCD-generated images has been developed. It involves removing unwanted objects and blemishes, subtracting the bias offset, removing the thermal background; correcting for ...
-
(Halifax, N.S. : Saint Mary's University, 1977)At the suggestion of Dr. D.L. DuPuy, the young open clusters of NGC 6604 and NGC 6704 were observed in the UBV wide-band system in order to obtain improved colour-magnitude diagrams and estimates of distance. A short ...
-
(Halifax, N.S. : Saint Mary's University, 1988)This thesis presents a stellar space density analysis in the galactic plane at l = 268 [degree sign]. The data consist of photographic UBV photometry for 2461 stars and MK spectral classifications for 1713 of these. A ...
-
(Halifax, N.S. : Saint Mary's University, 1979)The surface brightness profiles of a sample of supergiant and elliptical galaxies were studied. The original data were gathered by Dr. G.A. Welch, who also wrote the program (PROFIL) for the data reduction. This study ...
