Solar observations of the center-to-limb variation of several spectral lines were carried out in October 22-23, 1997, with the Gregory Coude Telescope (GCT) and its Czerny-Turner echelle spectrograph at the Observatorio del Teide (Tenerife, Spain). We secured spectra for 8 spectral setups in 6 different positions across the solar disk, as

There are three known Of?p stars in our galaxy, they are the well known peculiar stars HD108, HD148937 and HD191612. The question mark in their spectral classification was introduced by Walborn (1972) to indicate doubt that these stars are normal Of supergiants. They are characterised by their CIII 4647, 4650, 4651 emission lines being comparable

We present distance modulus and reddening determinations for 72 Galactic globular clusters from the homogeneous photometric database of Piotto et al. ([CITE]), calibrated to the HST flight F439W and F555W bands. The distances have been determined by comparison with theoretical absolute magnitudes of the ZAHB. For low and intermediate metallicity

We present a library of 1654 high-resolution stellar spectra, with a sampling of 0.3 Åand covering the wavelength range from 3000 to 7000 Å. The library was computed with the latest improvements in stellar atmospheres, incorporating non-local thermodynamic equilibrium (non-LTE) line-blanketed models for hot, massive (Teff>= 27500K) and line

The ING is organising a conference on "The Nature of V838 Mon and Its Light Echo", that will be held from May 16th to 19th, 2006, in the Hotel H10 Taburiente Playa in the beach resort of Los Cancajos, near Santa Cruz de la Palma.
