Diversity among other worlds: characterization of exoplanets by direct detection (2008)
Schneider, J., Boccaletti, A., Aylward, A., Baudoz, P., Beuzit, J. L., Brown, R., ...
The physical characterization of exoplanets will require to take spectra at several orbital positions. For that purpose, a direct imaging capability is necessary. Direct imaging requires an efficient...
Kelu-1 AB - A possible brown dwarf triple system (2008)
Stumpf, M. B., Brandner, W., Henning, Th., Bouy, H., Koehler, R., Hormuth, F., ...
We have monitored the benchmark L dwarf binary Kelu-1AB over the past 3 years to derive improved spectral types and luminosities for the individual components. The astrometric measurements enable us...
Design, analysis and test of a microdots apodizer for the Apodized Pupil Lyot Coronagraph (2008)
Martinez, P., Dorrer, C., Carpentier, E. Aller, Kasper, M., Boccaletti, A., Dohlen, K., ...
Coronagraphic techniques are required to detect exoplanets with future Extremely Large Telescopes. One concept, the Apodized Pupil Lyot Coronagraph (APLC), is combining an apodizer in the entrance...
Martinez, P., Boccaletti, A., Kasper, M., Cavarroc, C., Yaitskova, N., Fusco, T., ...
We compare coronagraph concepts and investigate their behavior and suitability for planet finder projects with Extremely Large Telescopes (ELTs, 30-42 meters class telescopes). For this task, we...
Spatially resolved H2 emission from the disk around T Tau N (2008)
Gustafsson, M., Labadie, L., Herbst, T. M., Kasper, M.
We report the detection of quiescent H2 emission in a spatially resolved ring-like structure within 100 AU of T Tau N. We present evidence to show that the emission most likely arises from shocks in...
Vérinaud, C., Hubin, N., Kasper, M., Antichi, J., Baudoz, P., Beuzit, J. L., ...
The Exo-Planets Imaging Camera and Spectrograph (EPICS), is the Planet Finder Instrument concept for the European Extremely Large Telescope (ELT). The study made in the frame of the OWL 100-m...
Search and investigation of extra-solar planets with polarimetry (2006)
Schmid, H. M., Beuzit, J. L., Feldt, M., Gisler, D., Gratton, R., Henning, Th, ...
L-band search for substellar companions in the Tucana and beta Pictoris moving groups (2006)
Kasper, M., Apai, D., Brandner, W., Close, L. M., Geißler, K.
Radial velocity surveys provide evidence that giant extrasolar planets are common, but their detection space is limited to only a few astronomical units from the stars. In order to close this gap,...
AO assisted NIR 3D spectroscopic imaging - Can an ELT see the earth at 10pc? (2006)
Feldt, Markus, Berton, Alessandro, Henning, Thomas, Gratton, Raffaele, Turatto, Massimo, Schmid, H. M., ...
Biller, B. A., Kasper, M., Close, L. M., Brandner, W., Kellner, S.
We present VLT/NACO SDI images of the very nearby star SCR 1845-6357 (hereafter SCR 1845). SCR 1845 is a recently discovered M8.5 star just 3.85 pc from the Sun. Using the capabilities of the unique...
A Planet Finder instrument for the VLT (2006)
Beuzit, J. L., Feldt, M., Mouillet, D., Moutou, C., Dohlen, K., Puget, P., ...

Koslowski, R., Barth, K., Augstein, A., Tschernig, T., Bargsten, G., Aufderheide, M., ...
The study of function and regulation of the phenotype of alveolar type I (AT I) epithelial cells is limited by the rareness of suitable cell lines or primary cultures of this cell type. We describe...
MACAO-VLTI first light: Adaptive optics at the service of interferometry (2003)
Arsenault, R., Alonso, J., Bonnet, H., Brynnel, J., Delabre, B., Donaldson, R., ...
The AO department of ESO has completed the design of an adaptive AO system for the VLT Interferometer. Ordering of components, manufacturing and integration took place in 2001 and 2002. The system is...
