J/ApJ/652/458  BVRHα photometry of candidates Be stars (Wisniewski+, 2006)

The role of evolutionary age and metallicity in the formation of classical Be circumstellar disks. I. New candidate Be stars in the LMC, SMC, and Milky Way. Wisniewski J.P., Bjorkman K.S. <Astrophys. J., 652, 458-471 (2006)> =2006ApJ...652..458W
ADC_Keywords: Magellanic Clouds ; Stars, Be ; Photometry Keywords: circumstellar matter - galaxies: clusters: individual: Bruck 60, Bruck 107, HW 43, LH 72, NGC 371, NGC 456, NGC 458, NGC 460, NGC 465, NGC 1850, NGC 1858, NGC 1955, NGC 2027, NGC 2186, NGC 2383, NGC 2439 - Magellanic Clouds - stars: emission-line, Be - techniques: photometric Abstract: We present B, V, R, and Hα photometry of eight clusters in the Small Magellanic Cloud, five in the Large Magellanic Cloud, and three Galactic clusters and use two-color diagrams (2-CDs) to identify candidate Be star populations in these clusters. We find evidence that the Be phenomenon is enhanced in low-metallicity environments, based on the observed fractional early-type candidate Be star content of clusters of age 10-25Myr. Description: Our photometry was obtained at the Cerro Tololo Inter-American Observatory (CTIO) 0.9m telescope using the direct-imaging CCD, a multiamplifier CCD, operated in the quad amplifier mode. Observations were made on 2002 Oct 12-16.
