The Star Formation Rate in disk galaxies: thresholds and dependence on gas amount
S. Boissier, N. Prantzos, A. Boselli +1
We reassess the applicability of the Toomre criterion in galactic disks and we study the local star formation law in 16 disk galaxies for which abundance gradients are published. T…
On the relative frequencies of core-collapse supernovae sub-types: the role of progenitor metallicity
Nikos Prantzos, Samuel Boissier
We show that the observed ratio of the subtypes Ib,c and II core-collapse supernovae depends on the metallicity of the host galaxy, as expected on theoretical grounds. However, the…
Chemical and spectrophotometric evolution of Low Surface Brightness galaxies
S. Boissier, D. Monnier Ragaigne, N. Prantzos +3
Based on the results of recent surveys, we have constructed a relatively homogeneous set of observational data concerning the chemical and photometric properties of Low Surface Bri…
On the early evolution of the Galactic Halo
Nikos Prantzos
It is shown that the low metallicity tail of the stellar metallicity distribution predicted by simple Outflow models for the Milky Way halo depends sensitively on whether Instantan…
Evolution of CNO abundances in the Universe
Nikos Prantzos
After summarizing the most important features of current stellar yields of CNO elements (including recent results concerning rotating and mass losing stars) I discuss how these yie…
