Descripción
Aims.We present reflectance spectra of three V-type Near-Earth Objects
obtained at the 3.6 m Telescopio Nazionale Galileo and at the 2.5 m
Nordic Optical Telescope covering the near-infrared and visible range,
respectively. The range from 0.5 to 2.5 μm, encompassing the 1 and 2
μm pyroxene features, allows a mineralogical characterization of
these asteroids. Methods: .A preliminary analysis using the
classical methods has been applied to establish some constraints on the
surface mineralogy of these objects. Then, the Modified Gaussian Method
was applied to gain further insight on the possible mineral components
present in the surface of the objects. Results: .The comparison
between these basaltic asteroids in near Earth orbits and the achondrite
basaltic meteorites shows a quite clear mineralogical link,
corroborating the long-standing hypothesis of the Near-Earth Objects
population as the immediate source of these meteorites.
