Nonextensive statistical effects on the relativistic nuclear equation of state

A. Drago, A. Lavagno, P. Quarati

Following the basic prescriptions of the Tsallis' nonextensive thermodynamics, we study the relativistic nonextensive thermodynamics and the equation of state for a perfect gas at…

Temperature dependence of modified CNO nuclear reaction rates in dense stellar plasmas

F. Ferro, A. Lavagno, P. Quarati

We study the dependence of the CNO nuclear reaction rates on temperature, in the range of K, the typical range of temperature evolution from a Sun-like star towards a w…

Non-extensive resonant reaction rates in astrophysical plasmas

F. Ferro, A. Lavagno, P. Quarati

We study two different physical scenarios of thermonuclear reactions in stellar plasmas proceeding through a narrow resonance at low energy or through the low energy wing of a wide…

D=4, N=2 Gauged Supergravity in the Presence of Tensor Multiplets

Riccardo D'Auria, Gianguido Dall'Agata, Luca Sommovigo +1

Using superspace techniques we construct the general theory describing D=4, N=2 supergravity coupled to an arbitrary number of vector and scalar--tensor multiplets. The scalar mani…

N=4 supergravity for Type IIB on T^6/Z_2 in presence of fluxes

Silvia Vaulá

We report on the construction of four dimensional gauged supergravity models that can be interpreted as type IIB orientifold compactification in presence of 3-form fluxes and D3--b…

Exact solutions for Bianchi type cosmological metrics, Weyl orbits of E_{8(8)} subalgebras and p--branes

P. Fré, K. Rulik, M. Trigiante

In this paper we pursue further a programme initiated in a previous work and aimed at the construction, classification and property investigation of time dependent solutions of sup…
