Polarization of K-shell dielectronic recombination satellite lines of Fe XIX-XXV and its application for diagnostics of anisotropies of hot plasmas

Chintan Shah, Pedro Amaro, René Steinbrügge +3

We present a systematic measurement of the X-ray emission asymmetries in the K-shell dielectronic, trielectronic, and quadruelectronic recombination of free electrons into highly c…

Investigating the interstellar dust through the Fe K-edge

D. Rogantini, E. Costantini, S. T. Zeegers +5

The chemical and physical properties of interstellar dust in the densest regions of the Galaxy are still not well understood. X-rays provide a powerful probe since they can penetra…

New astrometry and photometry for the companion candidates of CT Cha

T. O. B. Schmidt, R. Neuhäuser, M. Mugrauer +2

In our ongoing search for close and faint companions around T Tauri stars in the Chamaeleon star-forming region, we recently (Schmidt et al 2008b) presented direct observations and…

Finding new sub-stellar co-moving companion candidates - the case of CT Cha

T. O. B. Schmidt, R. Neuhäuser

We have searched for close and faint companions around T Tauri stars in the Chamaeleon star forming region. Two epochs of direct imaging data were taken with the VLT Adaptive Optic…

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…

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…
