Query: Abundance ratios in the hot ISM of elliptical galaxies   To constrain the recipes put forth to solve the theoretical Fe discrepancy in
the hot interstellar medium of elliptical galaxies and at the same time explain
the [alpha/Fe] ratios. In order to do so we use the latest theoretical
nucleosynthetic yields, we incorporate the dust, we explore differing SNIa
progenitor scenarios by means of a self-consistent chemical evolution model
which reproduces the properties of the stellar populations in elliptical
galaxies. Models with Fe-only dust and/or a lower effective SNIa rate achieve a
better agreement with the observed Fe abundance. However, a suitable
modification to the SNIa yield with respect to the standard W7 model is needed
to fully match the abundance ratio pattern. The 2D explosion model C-DDT by
Maeda et al. (2010) is a promising candidate for reproducing the [Fe/H] and the
[alpha/Fe] ratios. (A&A format)
