(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, 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 = ...
-
(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 ...
-
(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, 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 ...
-
(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, 2005)Sub-millimetre mapping of Orion B (L1630) using SCUBA on the James Clerk Maxwell Telescope has revealed a large population of compact cores (Mitchell et al. 2001). Using the CFHT-IR camera on the Canada-France-Hawaii ...
-
(Halifax, N.S. : Saint Mary's University, 1999)The three supernova remnants, 3C391, W28 and W44, are known to be interacting with their environmental molecular clouds. Our goal in studying such interactions is to determine whether compression by supernova shocks triggers ...
-
(Halifax, N.S. : Saint Mary's University, 2007)NGC 2024 is a star-forming region in Orion B which contains a dense molecular ridge and a number of dense cores seen by their dust emission (Mezger et al., 1992). This area is investigated using observations of four ...
-
(Halifax, N.S. : Saint Mary's University, 1993)In this thesis, the nature of the star forming core of the Mon R2 cloud is investigated using new, high spatial resolution observations. The new data include: maps of [superscript 12]CO J=3[right arrow]2, HCN J=4[right ...
-
(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 ...
