On the Origin of the most massive stars around R136
B. R. Brandl, S. Portegies Zwart, A. J. F. Moffat +1
We discuss the signature of a peculiar constellation of very massive stars at a projected distance of 2-3 pc around R136a. We discuss various scenarios for its possible origin, suc…
HST Imagery and CFHT Fabry-Perot 2-D Spectroscopy in Halpha of the Ejected Nebula M1-67: Turbulent Status
Yves Grosdidier, Anthony F. J. Moffat, Sébastien Blais-Ouellette +2
With HST-WFPC2 we have obtained a deep, H-alpha image of the WR nebula M1-67. With the interferometer of the Universite Laval (Quebec, Canada), we have obtained complementary Fabry…
NGC 3603 - a Local Template for Massive Young Clusters
B. Brandl, W. Brandner, F. Eisenhauer +3
We present a study of the star cluster associated with the massive Galactic HII region NGC3603 based on near-IR broad-- and narrowband observations taken with ISAAC/VLT under excel…
Low-mass stars in the massive HII region NGC 3603 - Deep NIR imaging with ANTU/ISAAC
B. Brandl, W. Brandner, F. Eisenhauer +3
We have observed NGC 3603, the most massive visible HII region known in the Galaxy, with ANTU(VLT1)/ISAAC in the near-infrared (NIR) J_s, H, and K_s bands. Our observations are the…
