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 multi-transition CO study of the GL 490 outflow

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 ...
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 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 ...
Empirical confirmation of the mass dependence for white dwarf luminosities

Beckett, Jeremy Robert Wilson (Halifax, N.S. : Saint Mary's University, 1993)

Existing calibrations of white dwarf luminosities have invariably relied upon the inhomogeneous sample of refractor parallaxes published in the General Catalogue of Trigonometric Parallaxes. We have completed a new calibration ...
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 ...
