We report complete near-infrared (0.9-2.4 mu m) spectral observations of trans-neptunian objects (TNOs) 2000 EB173 and 2000 WR106 collected using the new Near Infrared Camera Spectrometer (NICS) attached to the 3.56 m Telescopio Nazionale Galileo (TNG). Both spectra are very red and with a quite strong and broad drop extending throughout the K band

With the goal of confirming the metallicity ``excess'' present in stars with planetary-mass companions, we present in this paper a high-precision spectroscopic study of a sample of dwarfs included in the CORALIE extrasolar planet survey. The targets were chosen according to the basic criteria that 1) they formed part of a limited volume and 2) they

The highly convergent iterative methods developed by Trujillo Bueno and Fabiani Bendicho (1995) for radiative transfer (RT) applications are generalized to spherical symmetry with velocity fields. These RT methods are based on Jacobi, Gauss-Seidel (GS), and SOR iteration and they form the basis of a new NLTE multilevel transfer code for atomic and

EMIR (Espectrógrafo Multiobjeto Infrarrojo) is a near-infrared wide-field camera and multi-object spectrograph to be built for the 10.4 m GTC (Gran Telescopio Canarias) at La Palma. The Data Reduction Pipeline (DRP), which is being designed by the EMIR Universidad Complutense de Madrid Group, will be optimized for handling and reducing the near-IR

We reexamine closely the solar photospheric line at 6300 Å, which is attributed to a forbidden line of neutral oxygen and is widely used in analyses of other late-type stars. We use a three-dimensional time-dependent hydrodynamical model solar atmosphere that has been tested successfully against observed granulation patterns and an array of
