Cold dust around nearby stars (DUNES). First results: A resolved exo-Kuiper belt around the solar-like star zeta^2 Ret
C. Eiroa, D. Fedele, J. Maldonado +46
We present the first far-IR observations of the solar-type stars delta Pav, HR 8501, 51 Peg and zeta^2 Ret, taken within the context of the DUNES Herschel Open Time Key Programme (…
The Formation and Evolution of Planetary Systems: First Results from a Spitzer Legacy Science Program
M. R. Meyer, L. A. Hillenbrand, D. E. Backman +34
We present 3-160 micron photometry obtained with the IRAC and MIPS instruments for the first five targets from the Spitzer Legacy Science Program "Formation and Evolution of Planet…
Kuiper Belts Around Nearby Stars
R. Nilsson, R. Liseau, A. Brandeker +10
In order to detect and characterise cold extended circumstellar dust originating from collisions of planetesimal bodies in disks, belts, or rings at Kuiper-Belt distances (30-50 AU…
New Herbig Ae/Be stars confirmed via high-resolution optical spectroscopy
A. Carmona, M. E. van den Ancker, M. Audard +3
We present FEROS high-resolution (R~45000) optical spectroscopy of 34 Herbig Ae/Be star candidates with previously unknown or poorly constrained spectral types. Within the sample,…
A Planetary Companion around a Metal-Poor Star with Extragalactic Origin
J. Setiawan, R. Klement, T. Henning +4
We report the detection of a planetary companion around HIP 13044, a metal-poor star on the red Horizontal Branch. The detection is based on radial velocity observations with FEROS…
Large dust particles in disks around T Tauri stars
J. Rodmann, Th. Henning, C. J. Chandler +2
We present 7-mm continuum observations of 14 low-mass pre-main-sequence stars in the Taurus-Auriga star-forming region obtained with the Very Large Array with ~1.5" resolution and…
