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 …

The discovery of large numbers of young low-mass stars and brown dwarfs over the past
decade has made it possible to investigate star formation and early evolution in a previously …

We present an analysis of the intrinsic colors and temperatures of 5–30 Myr old pre-main-
sequence (pre-MS) stars using the F0-through M9-type members of nearby, negligibly …

Directly detecting thermal emission from young extrasolar planets allows measurement of
their atmospheric compositions and luminosities, which are influenced by their formation …

Context. The relevance of M dwarfs in the search for potentially habitable Earth-sized
planets has grown significantly in the last years. Aims. In our on-going effort to …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

The all sky surveys done by the Palomar Observatory Schmidt, the European Southern
Observatory Schmidt, and the United Kingdom Schmidt, the InfraRed Astronomical Satellite …

We combine optical, near-infrared, and mid-infrared spectra and photometry to construct
expanded spectral energy distributions for 145 field age (> 500 Myr) and 53 young (lower …

High-contrast near-infrared imaging of the nearby star HR 8799 has shown three giant
planets. Such images were possible because of the wide orbits (> 25 astronomical units …

We present results of the largest, most comprehensive study ever done of the stellar
multiplicity of the most common stars in the Galaxy, the red dwarfs. We have conducted an …
