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…
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…
Science with SIRTF - Some Examples
Bernhard Brandl, the IRS Team
The Space InfraRed Telescope Facility (SIRTF) is a space-borne, cryogenically-cooled infrared observatory capable of studying objects ranging from our Solar System to the distant r…
The Low-Mass Stars in Starburst Clusters
Bernhard Brandl, the NGC3603, the 30Doradus-Team
If star formation depends strongly on the global properties of the environment in which they form, the slope of the IMF as well as the upper and lower mass cut-offs would be expect…
Extragalactic Spectroscopy with SIRTF/IRS
B. Brandl, V. Charmandaris, K. Uchida +1
The Infrared Spectrograph (IRS) is one of the three instruments on board the Space Infrared Telescope Facility (SIRTF) to be launched in December 2001. The IRS will provide high re…
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…
