Observations of the transiting planet TrES-2 with the AIU Jena telescope in Großschwabhausen
St. Raetz, M. Mugrauer, T. O. B. Schmidt +9
We have started high precision photometric monitoring observations at the AIU Jena observatory in Grossschwabhausen near Jena in fall 2006. We used a 25 cm Cassegrain telescope equ…
The multiplicity of exoplanet host stars - New low-mass stellar companions of the exoplanet host stars HD125612 and HD212301
M. Mugrauer, R. Neuhaeuser
Aims: We present new results from our ongoing multiplicity study of exoplanet host stars, carried out with SofI/NTT. We provide the most recent list of confirmed binary and triple…
A search for wide brown dwarf companions to stars within 10pc
Marin Treselj, Andreas Seifahrt, Klaus-Werner Hodapp +2
We present the first results of a large imaging survey to identify wide brown dwarf companions to stars within 10 pc. We have performed a deep (H-band limit ~ 19.0 mag), wide field…
Spatially Resolved 3 micron Spectroscopy of Elias 1: Origin of Diamonds in Protoplanetary Disks
M. Goto, Th. Henning, A. Kouchi +8
We present spatially resolved 3 um spectra of Elias 1 obtained with an adaptive optics system. The central part of the disk is almost devoid of PAH emission at 3.3 um; it shows up…
Far-infrared spectra of hydrous silicates at low temperatures - Providing laboratory data for Herschel and ALMA
H. Mutschke, S. Zeidler, Th. Posch +3
Hydrous silicates occur in various cosmic environments, and are among the minerals with the most pronounced bands in the far infrared (FIR) spectral region. Given that Herschel and…
Spectral and temporal variations of the isolated neutron star RX J0720.4-3125: new XMM-Newton observations
M. M. Hohle, F. Haberl, J. Vink +5
In the past, the isolated, radio-quiet neutron star RX J0720.4-3125 showed variations in the spectral parameters (apparent radius, temperature of the emitting area and equivalent w…
