CDROM/APJS/V104/P071 OB Associations in LMC Superbubbles (Oey 1996) ================================================================================ UBV Photometry of OB Associations within Superbubbles of the Large Magellanic Cloud M. S. Oey <1996, ApJS, 104, 71> =1996ApJS..104...71O ================================================================================ Abstract: This work presents UBV photometry of the stellar populations associated with seven superbubble nebulae and five classical H II regions in the Large Magellanic Cloud. Although the nebular morphology of the superbubbles appears to be substantially evolved compared to the classical nebulae, the color-magnitude diagrams do not reveal any noticeable correlation between the resident stellar population and nebular morphology. The photometry presented here will be used in a forthcoming paper to examine further the stellar content and dynamics of these superbubbles. Keywords: H II regions -- ISM: bubbles -- Magellanic Clouds -- open clusters ans associations: general Description: Tables 4a-m provide the photometry for the OB associations of the sample, including both superbubbles and diffuse H II regions. Notes for individual objects are: DEM 31: Photometry for D31-2001 (Sk -67 17) listed from Ardeberg et al. 1972, A&AS, 6, 249. DEM 106: Stars with prefix D106A- have V photometry from a separate, short exposure. DEM 192: Stars with prefix D192A- have V photometry from a separate, short exposure. DEM 301: Photometry for D301-1005 listed from Massey et al. 1995, ApJ, 438, 188. Postscript versions of the plates in Figure 1 of the printed paper are included. Each is a V image of the OB association field, with bright stars identified. The remaining stars can be identified with the aid of coordinates given in Table 4a-m. Each individual frame is 3.8' x 3.8' square, with north up and east to the left.

Stars with a and b components are spectroscopic binaries, whose V magnitude has been estimated as described in the printed paper. However, the colors listed for both components are the original, combined colors determined for the composite object. The DAOPHOT errors for these objects are misleading, and have been deleted. e_V, e_B-V, e_U-B: These are the photometric errors computed by DAOPHOT and do not include systematic effects such as those introduced by aperture corrections and transformation errors. -------------------------------------------------------------------------------- ================================================================================ (End) Lee Brotzman [ADS] 03-May-96
