On the use of a non-extensive distribution in the solar plasma
A. Lavagno, P. Quarati
We describe the physical motivations why we are urged to look for an ionic equilibrium distribution function slightly different from the Maxwellian to calculate nuclear reaction ra…
Nonextensive statistical effects in nuclear physics problems
G. Kaniadakis, A. Lavagno, M. Lissia +1
Recent progresses in statistical mechanics indicate the Tsallis nonextensive thermostatistics as the natural generalization of the standard classical and quantum statistics, when m…
Non-Markovian effects in the solar neutrino problem
G. Gervino, G. Kaniadakis, A. Lavagno +2
The solar core, because of its density and temperature, is not a weakly-interacting or a high-temperature plasma. Collective effects have time scales comparable to the average time…
Non-Extensive Thermostatistical Approach of the Peculiar Velocity Function of Galaxy Clusters
A. Lavagno, G. Kaniadakis, M. Rego-Monteiro +2
We show that the observational data recently provided by Giovanelli et al. (1996 a, b) and discussed by Bahcall and Oh (1996) concerning the velocity distribution of clusters of ga…
