Traditionally, the lower edge of the Pair Instability (PI) mass gap was firmly established to occur at masses of 50 M$\odot$. This assumption has been questioned with recent Gravitational Wave (GW) observations, which has shown that there are black holes (BHs) present above the 50 M$\odot$ limit, prompting questions on how this occurs. We present stellar evolution models...

Classical-nova outbursts are thermonuclear explosions in the accreted envelope of a white dwarf in a close, mass-transferring binary system. Three-dimensional nova studies show that temperature fluctuations during the explosions cause dredge up of white-dwarf material that enriches nova ejecta up to about 60% metals. Conventionally, white-dwarf-envelope interface mixing is not modelled in 1D...

Type Ia supernovae (SNe Ia) play a key role in cosmic nucleosynthesis and serve as cosmological distance indicators. There is consensus that SNe Ia originate from the thermonuclear explosions of white dwarfs (WDs) but the explosion mechanism(s) that produce them are still not understood. In this talk I will focus on potential observational signatures for two different SNe Ia explosion...
