J/other/RMxAA/44.111    ubvyβ photometry of NGC 6882/5 stars  (Pena+, 2008)

On the nature of the open clusters in the direction of NGC 6882/5. Pena J.H., Peniche R., Garrido R., Paparo M., Garcia-Cole A. <Rev. Mex. Astron. Astrofis., 44, 111-123 (2008)> =2008RMxAA..44..111P
ADC_Keywords: Clusters, open ; Photometry, uvby, beta Keywords: open clusters and associations: general - open clusters and associations: individual (NGC 6882/5) - stars: variables - techniques: photometric Abstract: Unpublished uvby-β photoelectric photometry of the open cluster NGC 6882/5 is presented. Utilizing already tested distance determinations through photometric techniques, it is found that there are at least two distinct star accumulations in the direction of the open cluster NGC 6882/5. A brief discussion is made of the nature of the previously found short period variables. Description: All the observations were carried out at the Observatorio Astromonico Nacional at San Pedro Martir, Mexico with the 150cm telescope equipped with a spectrometer, in three seasons: July-August 1986 (four nights), Jun 1997 (6 nights) and July 2000 (4 nights).
