Nuclear Astrophysics: Observation, Experiment, Theory

Nuclear astrophysics is concerned with the impact and influence of nuclear structure and nuclear reactions on astrophysical processes from the beginning of the universe in the big bang through the evolution of stars. New astronomical observations, new accelerators and detection techniques, and fast growing computational power provide unprecedented opportunities for major advances in our understanding of the cosmos. The many connections between astronomical observations, astrophysical modelling efforts, nuclear structure and reaction theory, and experimental nuclear data provide major challenges for researchers in the field of nuclear astrophysics. It is the goal of this year's summer school to give an introduction to this exciting field. Astrophysical phenomena and observations that might benefit from new or improved nuclear physics input will be covered; an overview of experimental goals, techniques, and facilities will be given; and various theoretical approaches to nuclear structure and reactions will be discussed.

Supernovae and Nuclear Physics

OUTLINE:   At the end of their evolution massive stars run out of nuclear fuel. As a consequence the core of the star collapses triggering a (type II) supernova. Simulating core-collapse supernovae on a computer is a great challenge requiring an interplay of several physics disciplines. Nuclear physics plays a key role. The lectures will introduce the nuclear physics inputs needed in a supernova simulation. Increased computer power and more sophisticated nuclear models have recently allowed to improve the nuclear physics relevant for supernovae. These include electron captures and beta decays at stellar conditions, neutrino-nucleus reactions, neutrino opacities in dense nuclear matter, etc. Core collapse supernovae might also be a site of the r-process. In such a dynamical scenario beta decays and perhaps neutrino-nucleus reactions are crucial. Supernovae are also the site of neutrino nucleosynthesis.

The 7Be(p, gamma)8B reaction and solar neutrinos

OUTLINE:   I will describe our present knowledge of the astrophysical rate for the 7Be(p, gamma)8B reaction, and implications for our understanding of the solar production rate of high energy neutrinos and for neutrino physics.

Erich W. Vogt  TRIUMF

Nuclear halo states

OUTLINE:   Nuclear halo states are unusual states which involve very loosely bound nucleons - typically one or more neutrons extending far beyond the normal nuclear radius. Of course near the drip lines nucleons extend to large distances, but even in the valley of stability halo states are expected to be relatively common. The definition of such states and the criterion for their existence will be discussed as well as their impact on nuclear physics and astrophysical reaction rates.

Registration

SNIT 2002 is free for registered participants.

The registration form
[ PDF (18 KB) , gzipped PostScript (27 KB) , PostScript (51 KB) ]
should be downloaded, completed and faxed to Elly Driessen at TRIUMF. Please note that the number of participants will be limited to 40. Unfortunately, we are unable to provide financial support to cover travel or subsistence expenses.

Accommodation

A limited number of single and twin rooms has been set aside for SNIT 2002 participants at Place Vanier Residence on the UBC campus. The rate is CDN$22 per night, plus 15% tax. Guests need to bring their own towels and soap; bed linens will be provided and exchanged weekly.

The above rate will only be available if the accommodation request is received before June 1, 2002. (Note that June is high tourist season in Vancouver. At that time it is very difficult to find accommodations in this price range anywhere in the city.)

The accommodation form [ PDF (174 KB) ] should be downloaded, completed and faxed or mailed to the Reservations Office, Conferences and Accommodations at UBC, NOT to TRIUMF.

Travel Arrangements

Participants need to ensure that they have the proper travel documents and visas to enter Canada.

Vancouver can be reached by air (Vancouver International Airport - YVR), rail, bus, car, or boat. There is bus and taxi service for transportation between the airport, downtown, and the UBC campus. See this link for details.

Some current exchange rates are (as of March 2002):
CDN$1 = US$0.63   ;   CDN$1 = Euro 0.72   ;   CDN$1 = £0.44
