alpha :a constant that is not a constant?
G. Fiorentini, B. Ricci
We review the observational information on the constancy of the fine structure constant alpha. We find that small improvements on the measurement of ^{187}Re lifetime can provide s…
Bounds on hep neutrinos
G. Fiorentini, V. Berezinsky, S. Degl'Innocenti +1
The excess of highest energy solar-neutrino events recently observed by Superkamiokande can be in principle explained by anomalously high -neutrino flux . Without us…
A Mixed Solar Core, Solar Neutrinos and Helioseismology
S. Degl'Innocenti, B. Ricci
We consider a wide class of solar models with mixed core. Most of these models can be excluded as the predicted sound speed profile is in sharp disagreement with helioseismic const…
Helioseismology and standard solar models
S. Degl'Innocenti, W. A. Dziembowski, G. Fiorentini +1
We present a systematical analysis of uncertainties in the helioseismological determination of quantities characterizing the solar structure. We discuss the effect of errors on the…
Solar opacity, neutrino signals and helioseismology
B. Ricci
In connection with the recent suggestion by Tsytovich et al. that opacity in the solar core could be overestimated, we consider the following questions: i) What would a 10\% opacit…
Neutrinos from the Sun: experimental results confronted with solar models
Vittorio Castellani, Scilla Degl'innocenti, Gianni Fiorentini +2
For standard neutrinos, recent solar neutrino results together with the assumption of a nuclearly powered Sun imply severe constraints on the individual components of the total neu…
