Elemental gas-phase abundances of intermediate redshift type Ia supernova star-forming host galaxies
M. E. Moreno-Raya, L. Galbany, A. R. López-Sánchez +4
The maximum luminosity of type Ia supernovae (SNe Ia) depends on the oxygen abundance of the regions of the host galaxies where they explode. This metallicity dependence reduces th…

On the nitrogen abundance of FLIERs: the outer knots of the planetary nebula NGC 7009
Denise R. Goncalves, ; Barbara Ercolano, ; A. Carnero +2
We have constructed a 3D photoionisation model of a planetary nebula (PN) similar in structure to NGC 7009 with its outer pair of knots (also known as FLIERs --fast, low-ionization…
