Title:Characterising the diversity of V-band light-curves of supernovae type II



Abstract:

We present results on the characterisation of supernovae type II light-curves, using V-band photometry of 

118 well observed supernovae. We define magnitudes and decline rates to measure at different epochs 

and search for correlations between these parameters to aid in further understanding the diversity of 

hydrogen rich supernovae, while using these data to further our understanding of the physical mechanisms 

that underpin these explosive events. We find that events which are brighter at maximum light decline more 

quickly at all epochs, and we relate these correlations to more luminous supernovae having smaller 

hydrogen envelopes at the time of explosion. Furthering our knowledge of the physics of these trends will be 

critical in understanding the links between different progenitor properties and the diversity in transient 

features which we observe.
