The role of the star formation on the nitrogen abundance evolution
M. Mollá, J. M. Vílchez, A. I. Díaz +1
We analyze the evolution of nitrogen resulting from a set of spiral and irregular galaxy models computed for a large number of input mass radial distributions and with various star…

The Luminosity Function of Galaxies in the Hercules Cluster
R. Sánchez-Janssen, J. Iglesias-Páramo, C. Muñoz-Tuñón +2
We have imaged 1 deg in the V-band in the direction of the Hercules Cluster (Abell 2151). The data are used to compute for the first time the luminosity function (LF)…
