    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 cluster of class I/f/II young stellar objects discovered near the Cepheid SU Cas 
    Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W. (Oxford Academic, 2012-04)
    Preliminary constraints are placed on a cluster of young stellar objects (J2000 02:54:31.4 +69:20:32.5) discovered in the field of the classical Cepheid SU Cas. The Wide-field Infrared Survey Explorer (WISE) 3.4-, 4.6-, ...

    Effects of stellar rotation on young cluster HR diagrams 
    Geroux, Christopher M. (Halifax, N.S. : Saint Mary's University, 2007)
    This thesis investigates the effects of stellar rotation on the HR diagram location of members within young clusters. The rotational effects on luminosity and temperature of a star depend on the viewing angle and the ...

    New evidence supporting cluster membership for the keystone calibrator Delta Cephei 
    Majaess, Daniel J.; Turner, David Gerald, 1945-; Gieren, W. (IOP Publishing Limited, 2012-03-10)
    New and existing UBVJHKs, spectroscopic, NOMAD, Hubble Space Telescope, and revised Hipparcos observations are employed to determine properties for δ Cep and its host star cluster. The multi-faceted approach ...

    The Next Generation Virgo Cluster Survey (NGVS). I. Introduction to the survey 
    Ferrarese, Laura; Cote, Patrick; Cuillandre, Jean-Charles; Gwyn, S. D. J.; Peng, Eric W.; MacArthur, Lauren A.; Duc, Pierre-Alain; Boselli, A.; Mei, Simona; Erben, Thomas; Sawicki, Marcin, 1969- (American Astronomical SocietyIOP Publishing, 2012-05)
    The Next Generation Virgo Cluster Survey (NGVS) is a program that uses the 1 deg[superscript 2] MegaCam instrument on the Canada–France–Hawaii Telescope to carry out a comprehensive optical imaging survey of the Virgo ...

    The role of turbulence and magnetic fields in simulated filamentary structure 
    Kirk, Helen; Klassen, Mikhail; Pudritz, Ralph; Pillsworth, Samantha (American Astronomical Society, 2015-04-01)
    We use numerical simulations of turbulent cluster-forming regions to study the nature of dense filamentary structures in star formation. Using four hydrodynamic and magnetohydrodynamic simulations chosen to match observations, ...

    The young open cluster Stock 16: an example of star formation in an elephant trunk? 
    Turner, David Gerald, 1945- (American Astronomical Society, 1985-05-01)
    UBV photometry is presented for 33 stars in the young open cluster Stock 16 lying in the H II region RCW 75, and these observations are used to obtain new values for the reddening (E[subscript B-V] = 0.49 [plus or minus] ...
