Stars, Supernovae and Nucleosynthesis 2014

Scientific Rationale:
Stars and their supernovae play a key role in the universe through the light they shine, the chemical elements they produce and the powerful explosions that mark their death. Although stars have been studied for centuries, there are still many open questions concerning the physical processes at play in their interiors (e.g. convection, rotation, magnetic fields), interactions with binary companions and uncertainties in the nuclear reactions that powers them and produce the elements we are made of.
Progress in our understanding of stars, supernovae and the related nucleosynthesis requires input from both astronomical observations and theory as well as from nuclear experiments and theory. The BRIDGCE (BRIdging the Disciplines of Galactic Chemical Evolution ) network was thus set-up last year to coordinate research, facilitate knowledge transfer, and develop synergies between UK researchers involved in the study of the origin of the elements and the chemical and dynamical evolution of galaxies. This meeting, which will be organised on an annual basis, will bring together all the scientists involved in the BRIDGCE network activities to disseminate recent results, share new ideas and make future plans. Since most chemical elements are formed in stars and supernovae, the first day of the meeting will focus on the evolution and the explosion of stars, while the second day will focus on galactic chemical evolution, meteoritic grains and nuclear astrophysics.

Meeting details:
Title: Stars, Supernovae and Nucleosynthesis
Dates: 16-17 September
Venue: School of Physics and Chemistry, Lennard-Jones Laboratories, Keele University, Keele, ST5 5BG

Program:
Day 1 (Tue 16 Sept) will be the continuation of the massive stars and supernovae meetings organised by John Eldridge in the past.

Day 2 (Wed 17 Sept) will be the continuation of the meetings organised by Alison in York in the last few years.
