Asteroseismology of Procyon A with SARG at TNG

R. U. Claudi, A. Bonanno, S. Leccia +6

We present high precision radial velocity measurements on the F5 IV star alpha CMi obtained by the SARG spectrograph at TNG (Telescopio Nazionale Galileo) exploiting the iodine cel…

Proper Time Flow Equation for Gravity

A. Bonanno, M. Reuter

We analyze a proper time renormalization group equation for Quantum Einstein Gravity in the Einstein-Hilbert truncation and compare its predictions to those of the conceptually dif…

Solar model with CNO revised abundances

J. Montalban, A. Miglio, A. Noels +3

Recent three-dimensional, NLTE analyses of the solar spectrum have shown a significant reduction in the C, N, O and Ne abundances leading to a Z/X ratio of the order of 0.0177. We…

Spontaneous Symmetry Breaking and Proper-Time Flow Equations

A. Bonanno, G. Lacagnina

We discuss the phenomenon of spontaneous symmetry breaking by means of a class of non-perturbative renormalization group flow equations which employ a regulating smearing function…

Abundance differences between components of wide binaries

S. Desidera, R. Gratton, S. Scuderi +9

In this paper we present iron abundance analysis for 23 wide binaries with main sequence components in the temperture range 4900-6300 K, taken from the sample of the pairs currentl…
