Neutrino radiation in spherically-symmetric gravitational fields II. The structure of the radiation field
It is shown that the neutrino radiation field emitted by a star may be described by Vaidya's radiating Schwarzschild metric. The gravitational energy shift of the neutrino field is also considered, both in ter.....

A contribution to the rainich theory of the neutrino field II
Conditions are given on the metric of a space-time for it to admit a neutrino-gravitational field. The method described involves comparing the spin coefficients of a suitably defined tetrad of null vectors. It...

Neutrino radiation in spherically-symmetric gravitational fields I. The energy-momentum tensor for the one-neutrino and many-particle neutrino field
The physical situation of a star emitting neutrinos is considered. Some difficulties in the classical theory are mentioned, and a more detailed approach to the properties of neutrino radiation in general relat.....

Gravitational radiation and neutrinos
A class of neutrino-gravitational fields with zero energy-momentum tensor is defined. These space-times may also be interpreted as describing gravitational waves and are of Petrov typeD orN. A wave-like example o...

A contribution to the Rainich theory of the neutrino field
The neutrino-gravitational field is divided into fourteen distinct classes. This classification is shown also to determine the class of the space-time. Then for four particular classes of space-time, necessary...

Some physical properties of neutrino-gravitational fields
A new solution of the Einstein-neutrino field equations is given. This solution is of Plebanski class [4n]3 and describes a beam of neutrinos propagating along straight geodesies but possessing an inherent angula...
