Comet Calendar, The Official Event Calendar for UT Dallas en-us This week's events for Natural Sciences & Mathematics at UT Dallas Physics Colloquium: Into the Mantle of the Neutron Star: Probing Super(con)densed Matter under Extreme Conditions Wednesday, Sep 3
(4:15 p.m. - 5 p.m.)

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 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.
