A photoelectric study of three southern [delta] Scuti stars

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 ...
A photometric investigation of the fields of two short-period Cepheids in Cygnus

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. ...
A study of two open clusters containing Wolf-Rayet stars

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 ...
Photometric decomposition of NGC 6166

Blake, Ronald Melvin (Halifax, N.S. : Saint Mary's University, 1996)

We have used CFHT observations in Cousins B and R to probe the structure of the supergiant elliptical galaxy NGC 6166 in Abell 2199. We utilize the isophotal and aperture photometry of nuclei B and C to search for evidence ...
Surface photometry of the dominant galaxies in poor clusters

Fuller, Todd M. (Halifax, N.S. : Saint Mary's University, 1996)

Surface photometry in B and R is presented for seven brightest cluster galaxies (BCGs) in poor clusters. The primary goal was to detect diffuse envelopes around the BCGs to determine if they are genuine cD galaxies, which ...
Surface photometry of the Shell Galaxy NGC 2865

Wing, David Lee (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 ...
The stellar distribution and interstellar reddening in the Milky Way at l = 268 [degrees], b = 0 [degrees]

Slawson, Robert W. (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 ...
