Plasma Physics for Astrophysics
, 2020In this book, a distinguished expert introduces plasma physics from the ground up, presenting it as a comprehensible field that can be grasped largely on the basis of physical intuition and qualitative reasoning, similar to other fields of physics ...

An array of problems in astronomy, cosmology, and particle physics is dependent on our understanding of the evolution and structure of stars. Stellar structure and evolution, in turn, depend on how the nuclear energy generated in the stellar center is transported to the surface. Energy transport by photons is a primary transfer mechanism.

The previous chapter was devoted to the main observational evidence on the basis of our comprehension of the Universe and to their main theoretical implications. Some theoretical and phenomenological topics of particular relevance for current cosmology with clear observational counterparts are rediscussed here, with a better attention to the ...

Constraints are derived on the acceleration of charges in shocks to highly relativistic energies. When applied to the extended extragalactic radio sources and to the cosmic rays, they cast doubt on the mechanism of ‘in-situ acceleration’, both for energy, entropy and statistical mechanics reasons.

Astrophysical jets are linear structures associated with stars and galaxies which span about seven orders of magnitude in size; the largest jets emanating from galaxies are about 100 times the size of our galaxy and are the largest single objects in the universe.

Theoretical Nuclear Physics in Italy, 2003
In this report I will try to illustrate some of the main research themes and hot topics in nuclear astrophysics. The particular aim of the present report is to briefly illustrate the research activities, in the field of nuclear astrophysics, performed by the Italian nuclear physicist community within the "Programma di Ricerca di Interesse Nazionale su ...

My subject is a topic in astrophysical fluid dynamics; specifically, the behavior of the supersonic jets that are observed to squirt out of the nuclei of active galaxies, compact stellar objects, and proto-stars. Some years ago, I had the good fortune to discuss this topic with Hans Liepmann, who quickly recognized that astrophysical jets pose some ...
