Comet-like mineralogy of olivine crystals in an extrasolar proto-Kuiper belt
B. L. de Vries, B. Acke, J. A. D. L. Blommaert +20
Some planetary systems harbour debris disks containing planetesimals such as asteroids and comets. Collisions between such bodies produce small dust particles, the spectral feature…
Observational evidence for composite grains in an AGB outflow: MgS in the extreme carbon star LL Peg
R. Lombaert, B. L. de Vries, A. de Koter +5
The broad 30 μm feature in carbon stars is commonly attributed to MgS dust particles. However, reproducing the 30 μm feature with homogeneous MgS grains would require much more sul…
High-Contrast NIR Polarization Imaging of MWC480
N. Kusakabe, C. A. Grady, M. L. Sitko +52
One of the key predictions of modeling from the IR excess of Herbig Ae stars is that for protoplanetary disks, where significant grain growth and settling has occurred, the dust di…
Mid-IR imaging of the transitional disk of HD169142: Measuring the size of the gap
M. Honda, Koen Maaskant, Y. K. Okamoto +14
The disk around the Herbig Ae star HD\,169142 was imaged and resolved at 18.8 and 24.5\,m using Subaru/COMICS. We interpret the observations using a 2D radiative transfer model…
Herschel images of Fomalhaut. An extrasolar Kuiper Belt at the height of its dynamical activity
B. Acke, M. Min, C. Dominik +33
Fomalhaut is a young, nearby star that is suspected to harbor an infant planetary system, interspersed with one or more belts of dusty debris. We present far-infrared images obtain…
SPICES: Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems
Anthony Boccaletti, Jean Schneider, Wes Traub +28
SPICES (Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems) is a five-year M-class mission proposed to ESA Cosmic Vision. Its purpose is to image and charact…
On the physical structure of IRC+10216. Ground-based and Herschel observations of CO and CCH
E. De Beck, R. Lombaert, M. Agúndez +17
The C-rich AGB star IRC+10216 undergoes strong mass loss, and quasi-periodic density enhancements in the circumstellar matter have been reported. CO is ubiquitous in the CSE, while…
