Dr. Will Newton (Texas A&M Commerce)

     Neutron stars, born in the collapse of massive stellar cores, offer a fascinating glimpse into physics under the most extreme conditions. All four fundamental forces play an important role in determining the structure and dynamics of neutron stars, giving rise to a rich phenomenology manifest in observations over the whole electromagnetic spectrum. Understanding observed behaviors of neutron stars requires a close interplay of astrophysical observation and modeling, and nuclear physics experiment and theory. 

     I will present how our current understanding of neutron star structure has arisen from this interplay. Neutron stars have a thin (approx. 1km) solid crust surrounding a core (approx 10km in radius) of fluid nucleons. I will focus on the region where the crust transitions to the core, sometimes referred to as its mantle. This layer is expected to exhibit a number of fascinating material properties with strong analogies in soft condensed matter physics. I will detail the physics of the mantle, how we can go about testing our physical models observationally, and the fundamental nuclear physics questions that helps us answer.

Geosciences Seminar http://www.utdallas.edu/calendar/event.php?id=1220413558?WT.mc_id=CalendarRSS http://www.utdallas.edu/calendar/event.php?id=1220413558?WT.mc_id=CalendarRSS Friday, Sep 5
(3:30 p.m. - 4:30 p.m.)

The Department of Geosciences is pleased to announce the upcoming seminar and invite you to join us on Friday, September 5, 2014 at 3:30 p.m. in ROC 2.103.

Our distinguished guest speaker will be Dr. Oguz Gogus from Istanbul Technical University.  The title of his presentation will be: Surface and Crustal Responses to Lithospheric Removal Processes: Examples from Anatolia.

Refreshments are free and will be served after the seminar in ROC 2.301, the Geosciences Department.  We hope you will plan to attend.
