W0.00001: Rare isotopes and thermonuclear explosions: journey through the crust of an accreting neutron star Invited Speaker: Recent progress in nuclear astrophysics has been driven by simultaneous advances in observational astronomy, experimental nuclear physics and computational modeling. A prime example is the physics of accreting neutron stars in X- ray binaries. Nuclear reactions in the atmosphere, crust and in the liquid heavy metal ocean covering the surface of these neutron stars give rise to a range of observable phenomena such as X-ray bursts, superbursts, and millisecond oscillations, which in many cases have only been discovered recently. At the same time, a new generation of rare isotope beam accelerators has made it possible to begin to study experimentally the properties of the extremely unstable nuclei involved in these reactions. By following the fate of an accreted matter element through its journey into the deep crust of the neutron star I will review recent experimental and theoretical progress, discuss open questions, and outline avenues for the future that have the potential to achieve a better understanding of the physics of neutron stars.

W0.00002: The Double Simplex: Envisioning Particles and Interactions Invited Speaker: I will present a new way to envision the particles and interactions: a pair of interpenetrating tetrahedra that we might call the double simplex, in homage to the double helix that has just celebrated its fiftieth anniversary. Any chart or mnemonic device should be an invitation to narrative and a spur to curiosity, and that is what I intend for the double simplex. My goal is to represent what we know is true, what we hope might be true, and what we don't know--in other terms, to show the connections that are firmly established, those we believe must be there, and the open issues. I want also to express the spirit of play, of successive approximations, that animates the way scientists work. [Preview Abstract] |
