<p>On Friday, June 17 at <b>16:00 </b>Jennifer Barns (KITP) will
be giving the Astronomy Department Seminar on Zoom. Please note
the later time.</p>
<div><b>Searching for alternative sources of r-process elements</b><br>
</div>
<div><br>
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.</div>
<p>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. </p>
<p>Thanks<br>
