ADONIS high contrast infrared imaging of Sirius-B
Jean-Marc Bonnet-Bidaud, Eric Pantin
Sirius is the brightest star in the sky and a strong source of diffuse light for modern telescopes so that the immediate surroundings of the star are still poorly known. We study t…
Searching for molecular hydrogen mid-infrared emission in the circumstellar environments of Herbig Be stars
C. Martin-Zaidi, E. F. van Dishoeck, J. -C. Augereau +2
Context: Molecular hydrogen (H2) is the most abundant molecule in the circumstellar (CS) environments of young stars, and is a key element in giant planet formation. The measuremen…
Structural and compositional properties of brown dwarf disks: the case of 2MASS J04442713+2512164
H. Bouy, N. Huelamo, C. Pinte +15
In order to improve our understanding of substellar formation, we have performed a compositional and structural study of a brown dwarf disk. We present the result of photometric, s…
Dust observations of Comet 9P/Tempel 1 at the time of the Deep Impact
G. P. Tozzi, H. Boehnhardt, L. Kolokolova +15
On 4 July 2005 at 05:52 UT, the impactor of NASA's Deep Impact (DI) mission crashed into comet 9P/Tempel 1 with a velocity of about 10 km/s. The material ejected by the impact expa…
Detection of warm molecular hydrogen in the circumstellar disk around the Herbig Ae star HD97048
C. Martin-Zaidi, P-. O. Lagage, E. Pantin +1
We present high resolution spectroscopic mid-infrared observations of the circumstellar disk around the Herbig Ae star HD97048 with the VLT Imager and Spectrometer for the mid-Infr…
Dynamical modeling of the Deep Impact dust ejecta cloud
Tanyu Bonev, Nancy Ageorges, Stefano Bagnulo +17
The collision of Deep Impact with comet 9P/Tempel 1 generated a bright cloud of dust which dissipated during several days after the impact. The brightness variations of this cloud…
