The Hubble Space Telescope Treasury Program on the Orion Nebula Cluster
M. Robberto, D. R. Soderblom, E. Bergeron +27
The Hubble Space Telescope (HST) Treasury Program on the Orion Nebula Cluster has used 104 orbits of HST time to image the Great Orion Nebula region with the Advanced Camera for Su…
The low-mass Initial Mass Function in the Orion Nebula cluster based on HST/NICMOS III imaging
M. Andersen, M. R. Meyer, M. Robberto +2
We present deep HST/NICMOS Camera 3 F110W and F160W imaging of a 26'x33', corresponding to 3.1pcx3.8pc, non-contiguous field towards the Orion Nebula Cluster (ONC). The main aim is…
Quantitative Evidence for an Intrinsic Age Spread in the Orion Nebula Cluster
M. Reggiani, M. Robberto, N. Da Rio +3
Aims. We present a study of the distribution of stellar ages in the Orion Nebula Cluster (ONC) based on accurate HST photometry taken from the HST Treasury Program observations of…
NICMOS/HST Observations of the Embedded Cluster Associated with Mon R2: Constraining the sub-stellar Initial Mass Function
M. Andersen, M. R. Meyer, B. Oppenheimer +2
We have analyzed HST/NICMOS2 F110W, F160W, F165M, and F207M band images covering the central 1'x1' of the cluster associated with Mon R2 in order to constrain the Initial Mass Func…
The IMF in Extreme Star-Forming Environments: Searching for Variations vs. Initial Conditions
Morten Andersen, M. R. Meyer, J. Greissl +4
Any predictive theory of star formation must explain observed variations (or lack thereof) in the initial mass function. Recent work suggests that we might expect quantitative vari…
