<p>On Friday the 10th at 10:30 we have our final astronomy seminar
of the year with Héloïse Stevance (University of Auckland) via
Zoom.</p>
<p><b>The Life Story of AT 2017gfo</b><br>
<br>
Massive stars, and the menagerie of explosions resulting from
their deaths, are indispensable to creating a Universe that can
harbour life as we know it. Kilonovae are the explosions from
the merger of neutron stars, which are themselves the compact
remnants left from supernova events marking the death of massive
stars. They are a known site for neutron-rich element creation
in the Universe (such as gold), but the extent of their
contribution is still debated. A crucial piece of the puzzle is
understanding their ancestors and the life they led, but only
one kilonova has been detected so far: AT 2017gfo. In this talk
I will present how our binary stellar evolution models can help
us reconstruct the life story of the progenitor system of this
(so far) unprecedented event, and how we are preparing for
future kilonovae observations that will come in 2022/2023.<br>
</p>
<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>I want to take a moment to thank my fellow seminar organiser,
Tine Libbrecht, for her hard work this semester and to wish her
good luck in her future endeavours. Carolina Robustini will be
taking over from Tine in the new year. We will be continuing
with Zoom only seminars in the New Year but hope that if
conditions improve we will be able to have some hybrid seminars
later in the spring.<br>
</p>
<p>Thanks<br>
<br>
Chris and Tine</p>
<p>Christopher Usher is inviting you to a scheduled Zoom meeting.
