The program will bring together nuclear physicists, astrophysicists, and observational astronomers to address current issues and identify new directions in the study of explosive and transient astrophysical phenomena. The program will emphasize study of astrophysical phenomena through their multi-messenger and multi-wavelength signals, and will bring together observations in the optical band , x-rays, gamma rays, gravitational waves, and neutrinos.

The schedule for the 4 week program is designed to foster interactions among theorists, experimentalists and observers. Discussion topics include x-ray bursts, superbursts, magnetar flares, spin glitches in neutron stars, and core-collapse supernova.

Week 1: Modeling explosive phenomena (supernovae, novae, x-ray bursts, magnetar flares)
                Schedule

Week 2: Optical, neutrino, and gravitational wave astronomy.
                Schedule

Week 3: Gravitational waves from compact objects, glitches, and other transient behavior in neutron stars.
                Schedule

Week 4: Microphysical inputs (equation of state, rates, opacities) to macroscopic models.
                Schedule

From the perspective of theory and simulations, these diverse phenomena have much in common. Simulations rely on the development of improved transport methods for radiation, heat, and neutrinos, hydrodynamics, and nuclear reaction networks. Treatment of the underlying microphysics relies on theoretical methods to study nuclei and dense nuclear many-body systems, and strongly coupled plasmas. Identifying synergies between research efforts to study different transient explosive phenomena can lead to more realistic model predictions for observable signatures in photon, neutrino and gravitational wave emission. We anticipate that discussions pertaining to current efforts to study astrophysical transients through gamma-ray, x-ray and optical astronomy, in combination with experimental efforts in neutrino and gravitational wave detection, will guide the modeling efforts. Development of strategies to test specific model predictions and their implications for the underlying properties of matter at extreme density and temperature will be a guiding theme of the program.
