Comet 67P, the target of Rosetta mission, was observed in the visible and near-IR spectral regions during its perihelion approach. The observations were performed in four epochs, at heliocentric distances varying from about 3 to 1.4 AU, i. e. in the same range of the Rosetta mission. The aims of the observations were the study of the dust coma and

Integral field spectroscopy (IFS) is a technique that allows one to obtain the spectra of all the points of a bidimensional field of view simultaneously. It is being applied to the new generation of the largest night-time telescopes but it is also an innovative technique for solar physics. This paper presents the design of a new image slicer

We used the HARPS-North high resolution spectrograph (ℛ = 115 000) at Telescopio Nazionale Galileo (TNG) to observe one transit of the highly irradiated planet MASCARA-2b/KELT-20b. Using only one transit observation, we are able to clearly resolve the spectral features of the atomic sodium (Na I) doublet and the Hα line in its atmosphere, which are

A new method of representing star count data is shown which has the advantage over traditional methods of giving clear insights into the luminosity functions and density distributions of certain stellar components of the Galaxy. When this method is applied to data from the Two-Micron Galactic Survey (TMGS) it is seen that the luminosity function of

We present first results obtained from our spectroscopic survey of near-Earth objects (NEOSS), comprising a total of 102 visible and near-infrared spectra of asteroids. Visible data have been recorded with the 2.5-m Nordic Optical Telescope (NOT), while near-infrared spectra have been taken at 3.5-m Telescopio Nazionale Galileo, both telescopes
