Hello everybody,

Monday we are being visited by one of the candidates for our tenure-track hire, Dr. Matt Caplan.  Colloquium will start at 4:10 in Room 123.  I realize its an odd place and time, but please come if you are able.

Cheers,
Dr. Williams

Future Directions in Astromaterial Science
Dr. Matthew Caplan
McGill University



Dr. Caplan earned a BS in Physics from the University of Virginia in 2013 and completed his PhD in Physics at Indiana University in 2017.  He is currently a postdoctoral fellow at McGill Unversity’s McGill Space Institute in Montreal, Canada, working with Professor Andrew Cumming.

Abstract

Stars freeze. After their deaths in supernova the outer layers of neutron stars freeze and form a solid. In some ways this makes neutron stars like the earth, with a thin solid crust enveloping a liquid core. To interpret observations of neutron stars and constrain nuclear theory the 'astromaterials' in this crust must be understood. Broadly speaking, this crust has two components. Nuclei form solid crystal lattices near the top. Deeper, at the crust-core boundary, nuclei rearrange and form exotic shapes called "nuclear pasta." In this talk I will discuss recent simulations of these materials and their impacts on astrophysical observables, as well as future directions for this work.
