A new extensive library of PHOENIX stellar atmospheres and synthetic spectra
Aims. We present a new library of high-resolution synthetic spectra based on the stellar atmosphere code PHOENIX that can be used for a wide range of applications of spectral analysis and stellarExpand

Models of very-low-mass stars, brown dwarfs and exoplanets
Within the next few years, GAIA and several instruments aiming to image extrasolar planets will be ready. In parallel, low-mass planets are being sought around red dwarfs, which offer more favourableExpand

A ground-based transmission spectrum of the super-Earth exoplanet GJ 1214b
In contrast to planets with masses similar to that of Jupiter and higher, the bulk compositions of planets in the so-called super-Earth regime (masses 2–10 times that of the Earth) cannot be uniquelyExpand

Capitalizing on the observational advantage oered by its tiny M dwarf host, we present HST/WFC3 grism measurements of the transmission spectrum of the super-Earth exoplanet GJ1214b. These are the rstExpand

High-resolution UVES/VLT spectra of white dwarfs observed for the ESO SN Ia Progenitor Survey - III. DA white dwarfs
Context. The ESO Supernova Ia Progenitor Survey (SPY) took high-resolution spectra of more than 1000 white dwarfs and pre-white dwarfs. About two thirds of the stars observed are hydrogen-dominatedExpand

A featureless transmission spectrum for the Neptune-mass exoplanet GJ 436b
GJ 436b is a warm—approximately 800 kelvin—exoplanet that periodically eclipses its low-mass (half the mass of the Sun) host star, and is one of the few Neptune-mass planets that is amenable toExpand

The Optical and Near-infrared Transmission Spectrum of the Super-Earth GJ?1214b: Further Evidence for a Metal-rich Atmosphere
We present an investigation of the transmission spectrum of the 6.5 M ? planet GJ?1214b based on new ground-based observations of transits of the planet in the optical and near-infrared, and onExpand

Thermal structure of an exoplanet atmosphere from phase-resolved emission spectroscopy
Exoplanets that orbit close to their host stars are much more highly irradiated than their solar system counterparts. Understanding the thermal structures and appearances of these planets requiresExpand

The near-infrared spectral energy distribution of β Pictoris b
A gas giant planet has previously been directly seen orbiting at 8-10 AU within the debris disk of the ~12 Myr old star {\beta} Pictoris. The {\beta} Pictoris system offers the rare opportunity toExpand

Atmospheres From Very Low-Mass Stars to Extrasolar Planets
Within the next few years, several instruments aiming at imaging extrasolar planets will see first light. In parallel, low mass planets are being searched around red dwarfs which offer more favorableExpand
