[Astronomy seminar] Astronomy Department Seminar - June 17th Jennifer Barnes

[Astronomy seminar announcements]

On Friday, June 17 at *16:00 *Jennifer Barns (KITP) will be giving the 
Astronomy Department Seminar on Zoom. Please note the later time.

*Searching for alternative sources of r-process elements*

Rapid neutron capture (r-process) nucleosynthesis produces roughly half 
of the elements in the Periodic Table more massive than iron. The 
unusual conditions required for a successful r-process, in particular 
the requisite high flux of (unstable) free neutrons, have made the 
astrophysical site(s) in which the r-process occurs an enduring mystery. 
Observations of the first detected neutron star merger, GW170817, in 
both electromagnetic and gravitational radiation yielded evidence that 
merging neutron stars, long favored theoretically as r-process sources, 
did indeed undergo heavy element nucleosynthesis. However, these same 
observations suggested that neutron star mergers may not be unique in 
their ability to produce r-process elements. I will present new insights 
on r-process sources, with a particular focus on rare supernova 
explosions, and discuss how radiation from explosive r-process 
transients may help us unlock the origin of the heaviest elements in the 
Universe.

We are trying something new this year with leaving the Zoom call open 
after the formal hour of the seminar is up to allow the speaker, if they 
wish, to chat informally with anyone who is interested.

Thanks
Chris and Carolina
