PublicaciónThe vertical stellar distribution in NGC 6504: Detection of a thick disk
The vertical stellar distribution of the edge-on spiral NGC 6504 is examined in seven bands (U, B, R, I, J, H, K) by fitting model distributions to the light...

PublicaciónThe visible and near-infrared spectra of asteroids in cometary orbits
Context. Dynamical and albedo properties suggest that asteroids in cometary orbits (ACOs) are dormant or extinct comets. Their study provides new insights for...
