Abstract:
A fully general relativistic nonlinear model of the formation of massive
neutrino halos in an Einstein-Straus universe was given by Fabbri,
Jantzen and Ruffini (1982). The paper considers the role which a
nonvanishing, repulsive cosmological constant Lambda greater than 0,
admissible by observational limits, can have in the FJR model. The main
conclusion is that the influence of Lambda is negligible in the FJR
model for massive neutrinos with mass of about 10 eV, indicated by
recent observations of SN 1987a. On the other hand, the cosmological
constant is relevant in the model, if neutrinos have low mass, less than
0.2 eV.
