Recovery from population III supernova explosions and the onset of second generation star formation

open access: yes, 2014
We use cosmological simulations to assess how the explosion of the first stars in supernovae (SNe) influences early cosmic history. Specifically, we investigate the impact by SNe on the host systems for Population~III (Pop~III) star formation and explore

Type Ia Supernovae inside Planetary Nebulae: Shaping by Jets

open access: yes, 2013
Using 3D numerical hydrodynamical simulations we show that jets launched prior to type Ia supernova (SN Ia) explosion in the core-degenerate scenario can account for the appearance of two opposite lobes ('Ears') along the symmetry axis of the SN remnant (
