J/A+A/521/A61  Stars associated to Eagle Nebula (M16=NGC6611)  (Guarcello+ 2010)

Chronology of star formation and disks evolution in the Eagle Nebula. Guarcello M.G., Micela G., Peres G., Prisinzano L., Sciortino S. <Astron. Astrophys. 521, A61 (2010)> =2010A&A...521A..61G
ADC_Keywords: Clusters, open ; Photometry, UBVRI ; Photometry, infrared ; Photometry, millimetric/submm Keywords: protoplanetary disks - stars: formation - stars: pre-main sequence - infrared: stars: X-rays: stars Abstract: Massive star-forming regions are characterized by intense ionizing fluxes, strong stellar winds and, occasionally, supernovae explosions, all of which have important effects on the surrounding media, on the star-formation process and on the evolution of young stars and their circumstellar disks. We present a multiband study of the massive young cluster NGC 6611 and its parental cloud (the Eagle Nebula) with the aim of studying how OB stars affect the early stellar evolution and the formation of other stars. We search for evidence of triggering of star formation by the massive stars inside NGC 6611 on a large spatial scale (∼10 parsec) and ongoing disk photoevaporation in NGC 6611 and how its efficiency depends on the mass of the central stars. Description: This catalog contains coordinates and both optical and infrared photometry, plus usefull tags, of the candidate stars associated to the Eagle Nebula (M16), bost disk-less and disk-bearing, selected in Guarcello et al. 2010: "Chronology of star formation and disks evolution in the Eagle Nebula". The optical photometry in BVI bands comes from observations with WFI@ESO (Guarcello et al. 2007, Cat. J/A+A/462/245); JHK photometry have been obtained from 2MASS/PSC (Bonatto et al. 2006A&A...445..567B, Guarcello et al. 2007, Cat. J/A+A/462/245) and UKIDSS/GPS catalogs (Guarcello et al., 2010, in prep.) ; IRAC data are from GLIMPSE public survey (Indebetouw 2007ApJ...666..321I, Guarcello et al., 2009, Cat. J/A+A/496/453); X-ray data from three observations with Chandra/ACIS-I (Linsky et al., 2007, Cat. J/ApJ/654/347, Guarcello et al., 2007, J/A+A/462/245, Guarcello et al. 2010, in prep.). File Summary:

Note (1): tag which is equal to '2M' if the JHK photometry comes from 2MASS/PSC or equal to 'UK' if the JHK photometry comes from the UKIDSS/GPS catalog Note (3): JHK Excess flag as follows: 0 = star does not show excesses in the particular band 1 = the source has an excess 2 = the source has been selected from the catalog published in Guarcello et al., 2009, Cat. J/A+A/496/453 3 = the sources is classified as a 'probable member' by Guarcello et al., 2010, in prep.
