GJ1214b is an extremely interesting 6.55Mearth and 2.6 Earth radii sub-Neptune planet orbiting a M-dwarf host. Its proximity, only 14pc, makes it an excellent...

High-resolution spectroscopy (R>25,000) is a robust and powerful tool in the near-infrared characterization of exoplanet atmospheres. It has unambiguously...

Here we present a review of the new generation near infrared spectrographs (1 to 5 microns) available in telescopes from 3.5 m to 10 m in diameter. These...

This paper presents a new generation of long linear butted arrays developed at LETI / LIR and dedicated to high resolution IR imaging for space and airborne...

Ongoing and future optical and near-infrared surveys focused on the study of the Galactic plane are briefly presented. Their potential is illustrated by the...

We utilize the concept of sparsity or compressibility to develop an new generation of inversion codes for the Stokes parameters. The inversion code uses...

The HST/ACS Survey of Galactic Globular Clusters includes F606W and F814W observations of 66 clusters (Sarajedini et al. 2007). We present new global mass...
