Constraining the orbit of the possible companion to Beta Pictoris: New deep imaging observations (2009)

Lagrange, Anne-Marie, Kasper, Markus, Boccaletti, Anthony, Chauvin, Gaël, Gratadour, Damien, Fusco, Thierry, ...

We recently reported on the detection of a possible planetary-mass companion to Beta Pictoris at a projected separation of 8 AU from the star, using data taken in November 2003 with NaCo, the...

Photometric and spectroscopic detection of the primary transit of the 111-day-period planet HD 80606 b (2009)

Moutou, Claire, Hebrard, Guillaume, Bouchy, Francois, Eggenberger, Anne, Boisse, Isabelle, Bonfils, Xavier, ...

We report the detection of the primary transit of the extra-solar planet HD 80606 b, thanks to photometric and spectroscopic observations performed at Observatoire de Haute-Provence, simultaneously...

Coronography with adaptive optics: the ADONIS coronograph (2007)

Jean-luc Beuzit, David Mouillet, Anne-marie Lagrange, David Le Mignant

The combination of adaptive optics and coronographic techniques providing at the same time high angular resolution and high dynamic range is a powerful tool to study the close environment of bright...

Search for exoplanets with the radial-velocity technique: quantitative diagnostics of stellar activity (2007)

Desort, Morgan, Lagrange, Anne-Marie, Galland, Franck, Udry, Stephane, Mayor, Michel

Aims: Stellar activity may complicate the analysis of high-precision radial-velocity spectroscopic data when looking for exoplanets signatures. We aim at quantifying the impact of stellar spots on...

The Arches Cluster - Evidence for a Truncated Mass Function? (2005)

Stolte, Andrea, Brandner, Wolfgang, Grebel, Eva K., Lenzen, Rainer, Lagrange, Anne-Marie

We have analyzed high-resolution, adaptive optics (AO) HK observations of the Arches cluster obtained with NAOS/CONICA. With a spatial resolution of 84 mas, the cluster center is uniquely resolved....

Hot Very Small dust Grains in NGC 1068 seen in jet induced structures thanks to VLT/NACO adaptive optics (2003)

Rouan, Daniel, Lacombe, François, Gendron, Eric, Gratadour, Damien, Clénet, Yann, Lagrange, Anne-Marie, ...

We present K, L and M diffraction-limited images of NGC 1068 obtained with NAOS+CONICA at VLT/YEPUN over a 3.5" field around the central engine. Hot dust (Tcol = 550-650 K) is found in three...

VLT/NACO infrared adaptive optics images of small scale structures in OMC1 (2003)

Lacombe, François, Gendron, Eric, Rouan, Daniel, Clénet, Yann, Lemaire, Jean-Louis, Lagrange, Anne-Marie, ...

Near-infrared observations of line emission from excited H2 and in the continuum are reported in the direction of the Orion molecular cloud OMC1, using the European Southern Observatory Very...
