Astro Seminar

Characterising the explosion and progenitor properties of hydrogen-rich supernovae

Speaker: Claudia Gutierrez (Southampton)
Date: Wednesday 11 November 2020
Time: 16:00
Venue: Zoom

Type II Supernovae (SNe II) are produced by the final explosions of massive stars (>8 M ), which retain a significant part of their hydrogen envelopes before the explosion. These SNe show a large diversity in their transient behaviour, which is likely determined by differences, not just in explosion properties, but also in the progenitor star characteristics. In this talk, I will present the current status of SNe II studies, in particular, the results of the analysis of a new sample of SNe II occurring within low-luminosity galaxies. I will also describe the challenges in the determination of the explosion and progenitor parameters for these objects.
