Investigating the properties of stripped-envelope supernovae, what are the implications for their progenitors?

Understand

We present observations and analysis of 18 stripped-envelope supernovae observed during 2013 -- 2018.

• This sample consists of 5 H/He-rich SNe, 6 H-poor/He-rich SNe, 3 narrow lined SNe Ic and 4 broad lined SNe Ic.
• The peak luminosity and characteristic time-scales of the bolometric light curves are calculated, and the light curves modelled to derive 56Ni and ejecta masses (MNi and Mej).
• Additionally, the temperature evolution and spectral line velocity-curves of each SN are examined.
