A collection of various research projects in astronomy

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 ...
A study of the brightness variations in the red supergiant BC Cygni

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 ...
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 ...
A UBV study of the field of NGC 7790

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 ...
A UBV study of the fields surrounding two long-period cepheids and an adjacent open cluster in Carina

Danks, Terence A. (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 ...
