Description
This paper presents examples of star-forming phenomena in the discs of spirals which show symptoms of phase-coherence over kpc scales. Cases are found where, along an arm, the youngest blue stars are coherently displaced from a recent but older generation of redder evolved supergiants; in other cases, the star formation efficiency in arms appears to be responding to a density wave resonance pattern. Cases were also found with axisymmetric outflow in the disc components of circumnuclear starburst zones, which could account for an evolutionary starburst-LINER sequence.

    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
