The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot
Jupiters) have been probed for nearly two decades,. They allow us to investigate the …

In no other field of astrophysics has the impact of new instrumentation been as substantial
as in the domain of exoplanets. Before 1995 our knowledge of exoplanets was mainly based …

Earth-like planets, dark energy and variability of fundamental physical constants can be
discovered by observing wavelength shifts in the optical spectra of astronomical objects …

Aims. In the framework of the GIARPS High-resolution Observations of T Tauri stars (GHOsT)
project, we study the accretion properties of 37 classical T Tauri stars of the Taurus-Auriga …

Radiative transfer (RT) is a key component for investigating atmospheres of planetary
bodies. With the 3D nature of exoplanet atmospheres being important in giving rise to their …

Context. Disk winds play a fundamental role in the evolution of protoplanetary systems. The
complex structure and dynamics can be investigated through the emission of atomic and …

Optical velocimetry has led to the detection of more than 500 planets to date and there is a
strong effort to push m/s velocimetry to the near-infrared to access cooler and lighter stars …

Context. Recently, there have been a series of detections of molecules in the atmospheres
of extrasolar planets using high spectral resolution (R~ 100 000) observations, mostly using …

Aims. Determining the intensity of lines and continuum airglow emission in the H-band is
important for the design of faint-object infrared spectrographs. Existing spectra at low or …

The quest for extrasolar planets and their characterization as well as studies of fundamental
physics on cosmological scales rely on capabilities of high-resolution astronomical …
