J/ApJ/675/1319      Infrared photometry of NGC 3603          (Harayama+, 2008)

The initial mass function of the massive star-forming region NGC 3603 from near-infrared adaptive optics observations. Harayama Y., Eisenhauer F., Martins F. <Astrophys. J., 675, 1319-1342 (2008)> =2008ApJ...675.1319H
ADC_Keywords: H II regions ; Photometry, infrared Keywords: H II regions - open clusters and associations: individual (NGC 3603) - stars: formation - stars: luminosity function, mass function - stars: pre-main sequence Abstract: We study the initial mass function (IMF) of one of the most massive Galactic star-forming regions NGC 3603 to answer a fundamental question in current astrophysics: is the IMF universal, or does it vary? Using our very deep, high angular resolution JHKSL' images obtained with NAOS-CONICA at the VLT at ESO, we have successfully revealed the stellar population down to the subsolar mass range in the core of the starburst cluster. Description: Observations were carried out in two periods, on 2003 March 18-21 and 2005 February 14-16, using the AO system NACO at the VLT at ESO on Paranal, Chile. In the following analysis we mainly use the data obtained in the second observing run because of its better data quality. In addition to the high-resolution NACO observations of the cluster center, we analyzed the VLT/ISAAC JSHKS-band data sets of a wider field of view retrieved from the ESO archive facility.

Note (1): Source location is shown in an offset from the center of the cluster (J2000): 11:15:07.337-61:15:38.19 (instead of 11:15:05.90-61:15:28.4 as indicated in the paper) Note (2): Note that, since the photometric calibration of the L' band photometry was done by merely one data set of a standard star, the presented L' band magnitude has to be considered as a roughly-calibrated photometry. Note (3): Adopted from a list in Crowther & Dessart (1998MNRAS.296..622C) (Tab. 8 therein) which consists of spectra types in their study combined with those in Moffat (1983A&A...124..273M) and Drissen et al. (1995AJ....110.2235D). Note (4): Designated IDs of potential counterparts in HST optical detections by Moffat et al. (1994ApJ...436..183M), named <Cl* NGC 3603 MDS NN> in Simbad. Note (5): IDs originated in previous works such as Melnick et al. (1989A&A...213...89M); letters were adopted from tables in Moffat et al. (1994ApJ...436..183M). The letters A-F were originated in van den Bos (1928BAN.....4..261V) (G in Walborn 1973ApJ...182L..21W), and the source A was resolved into A1-3 by Hofmann & Weigelt (1986A&A...167L..15H). Note (6): Notes as follows: c1 = Star 19 and 45 together would correspond to MDS-61 (G/MTT-10) c2 = Star 55 and 57 together would correspond to MDS-67 (MTT-36) c3 = Multiple detections. MDS-58 and 62 correspond to MTT-15 c4 = MDS-8 and 9 correspond to MTT-21 c5 = MDS-49, 50, 52, and 53 correspond to D c6 = MDS-68 and 69 correspond to MTT-44 c7 = MDS-10 and 11 correspond to MTT-22 c8 = MDS-12 and 13 correspond to MTT-30 c9 = A1, A2, and A3 together consist of a X-ray source within the match of smoothed PSF in Moffat et al. (2002ApJ...573..191M) c10 = MDS-49 and 50 together consist of a X-ray source Note (7): Designated IDs of potential counterparts in a mid-infrared detections by Nurnberger & Stanke (2003A&A...400..223N, [NS2003] NNA in Simbad). The 11.9 micron sources 6A-F are in the concentrated cluster core. Note (8): Notes as follows: d1 = Star 19, 33 and 51 together would correspond to 6G d2 = Star 18 and 43 together would correspond to 6K d3 = Star 17 and 22 together would correspond to 6N Note (9): IDs in Sung & Bessell (2004, Cat. J/AJ/127/1014, [SB2004] NNNNN in Simbad) (Tab. 2 therein). Sources brighter than V=14mag detected in their analysis of the HST/PC1 archival data set.
