VLT near- to mid-IR imaging and spectroscopy of the M17 UC1-IRS5 region
Zhiwei Chen, Dieter E. A. Nuernberger, Rolf Chini +2
We investigate the surroundings of the hypercompact HII region M17 UC1 to probe the physical properties of the associated young stellar objects and the environment of massive star…
The substellar content of the ONC
Holger Drass, Rolf Chini, Dieter Nürnberger +5
The Substellar Initial Mass Function (SIMF) of many star-forming regions is still poorly known but the detailed knowledge of its shape will help to distinguish among the substellar…
Mid-infrared interferometry towards the massive young stellar object CRL 2136: inside the dust rim
W. J. de Wit, M. G. Hoare, R. D. Oudmaijer +3
We apply mid-infrared spectro-interferometry to the massive young stellar object CRL2136. The observations were performed with the Very Large Telescope Interferometer and the MIDI…
A brown dwarf companion to the intermediate-mass star HR6037
N. Huelamo, D. E. A. Nuernberger, V. D. Ivanov +8
In the course of an imaging survey we have detected a visual companion to the intermediate-mass star HR 6037. In this letter, we present two epoch observations of the binary with N…
Mid-infrared interferometry of the massive young stellar object NGC3603 - IRS 9A
S. Vehoff, C. A. Hummel, J. D. Monnier +5
We present observations and models for one of these MYSO candidates, NGC3603 IRS 9A. Our goal is to investigate with infrared interferometry the structure of IRS 9A on scales as sm…
A frozen super-Earth orbiting a star at the bottom of the Main Sequence
D. Kubas, J. P. Beaulieu, D. P. Bennett +19
We observed the microlensing event MOA-2007-BLG-192 at high angular resolution in JHKs with the NACO adaptive optics system on the VLT while the object was still amplified by a fac…
A VLT/NACO Study of Star Formation in the Massive Embedded Cluster RCW 38
K. L. DeRose, T. L. Bourke, R. A. Gutermuth +4
We present adaptive optics (AO) near-infrared (JHKs) observations of the deeply embedded massive cluster RCW 38 using NACO on the VLT. Narrowband AO observations centered at wavele…
Near-infrared follow-up to the May 2008 activation of SGR 1627-41
A. de Ugarte Postigo, A. J. Castro-Tirado, S. Covino +3
On 28 May 2008, the Swift satellite detected the first reactivation of SGR 1627-41 since its discovery in 1998. Following this event we began an observing campaign in near infrared…
Spatially resolved near-infrared spectroscopy of the massive star-forming region IRAS 19410+2336
N. L. Martin-Hernandez, A. Bik, E. Puga +2
IRAS19410+2336 is a young massive star forming region with an intense outflow activity. We present here spatially resolved NIR spectroscopy which allows us to verify whether the H2…
