Description
The results of near-infrared mapping, optical spectroscopy, and millimetric CO J = 2-1 observations of the halo about IC 418 are presented. As a result, it is confirmed that NIR emission extends outside of the principal emission shell, and into a zone characterized by weak optical grain scattering and (in all probability) strong FIR emission. An analysis of the optical and FIR data suggests an overall shell mass of 0.026 solar mass (for an assumed distance 0.412 kpc), although the absence of associated CO emission suggests that the shell, if neutral, must possess a relatively low molecular abundance.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    ANDES, the high resolution spectrograph for the ELT: science goals, project overview, and future developments
    The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph). ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength
