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 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 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.).

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.
