<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>
