Artist's concept of SN1006
Light Echos
What else are SNe important for?
Feedback in galaxy formation
Nucleosynthesis
Rung in the Cosmic distance ladder
Cosmic Rays
Different kinds of supernovae
Supernova rates
\frac{r_{II}}{r_{Ia}} \approx \frac{r_{Ia}}{r_{Ib/c}} \approx 2
r_{II} \approx 10^{-2} \rm year^{-1}
per galaxy
Relics
Non detected for type Ia
Companions
Observations favour a degenerate companion
\rho \propto \frac{\dot{M}}{v_w}
Double Degenerate Models
Roche Lobe Overflow
Merger
Collision
Lidov Kozai Mechanism
\cos i \sqrt{1-e^2} = \rm const
conservation of one component of the angular momentum
Collision induced Detonation
Zeldovich Criterion
\frac{u}{\dot{u}} > \frac{L}{c_s}
Converging velocity field
Double Ni56 Peak
Enter LBT
Observations
Spectra
Final Tally
Consistent with previous estimates
The curious case of LP 40-365
Two More hypervelocity white dwarf in GAIA DR2
Not just fast - also hot
Outside evolutionary track
Strange Composition
Survivor of type Iax supernova?
Mertis
but...
