Nuclear Problems in Astrophysics
These lectures, presented at the International School of Physics " Enrico Fermi, " deal with two major themes. The first is the remarkable story of the solar neu-trino problem, which (along with the atmospheric neutrino anomaly) recently led to the discovery of massive neutrinos and neutrino oscillations, physics beyond the standard model. I will describe the physics of the standard solar model...
متن کاملFundamental Unsolved Problems in Physics and Astrophysics
There is given a list and discussion of what are arguably the top 20 unsolved problems in physics and astrophysics today. The list ranges from particle physics to cosmology. Possible resolutions are noted, but without judgement. Perhaps the most remarkable aspect of the discussed problems is that they are closely interrelated. This opens the prospect that a solution to one or a few may lead to ...
متن کاملEvaluation of Linear Solvers for Astrophysics Transfer Problems
In this work we consider the numerical solution of a radiative transfer equation for modeling the emission of photons in stellar atmospheres. Mathematically, the problem is formulated in terms of a weakly singular Fredholm integral equation defined on a Banach space. Computational approaches to solve the problem are discussed, using direct and iterative strategies that are implemented in open s...
متن کاملNonextensive Statistical Effects on Nuclear Astrophysics and Many-body Problems
Density and temperature conditions in many stellar core (like the solar core) imply the presence of nonideal plasma effects with memory and long-range interactions between particles. This aspect suggests the possibility that the stellar core could not be in a global thermodynamical equilibrium but satisfies the conditions of a metastable state with a stationary (nonextensive) power law distribu...
متن کاملAstrophysics.
Using the oscillation frequencies of α Cen A recently discovered by Bouchy & Carrier (2001, 2002), the available astrometric, photometric and spectroscopic data, we tried to improve the calibration of the visual binary system α Cen. With the revisited masses of Pour-baix et al. (2002) we do not succeed to obtain a solution satisfying all the seismic observational constraints. Relaxing the const...
