Location:  Auditorium          

Speaker:   Richard Cyburt (National Superconducting Cyclotron Laboratory)

Title:     The continuing adventures of Bob the proton

Abstract: When we last left Bob, he had guided us through his life in the well known astrophysical environments of big bang nucleosynthesis and stellar evolution.  There are also many paradigms from which Bob can draw his experiences that are less well understood.  Experimental efforts today are  largely driven by the nuclear astrophysics involving exotic nuclei, either on the neutron rich side of stability (r-process) or on the proton rich side of stability (rp-process).  In this talk I will discuss the unstable hydrogen and helium burning on the surfaces of neutron stars, resulting in Type I X-ray bursts seen by observers.  I will present how we ascertain the importance of nuclear reactions in these scenarios and what how their variation impacts the X-ray light curves. In the end, Bob will guide us to where experiment can improve our understanding of these burst events and eventually allow us to constrain neutron star physics.

Stimulants available 15 minutes before the talk.
