Search for 7Be in the outburst of four recent novae
Paolo Molaro, Luca Izzo, Piercarlo Bonifacio +3
Following the recent detection of 7Be in the outburst spectra of Classical Novae we report the search for this isotope in the outbursts of four recent bright novae by means of high…
The UVES Large Program for Testing Fundamental Physics: I Bounds on a change in alpha towards quasar HE 2217-2818
P. Molaro, M. Centurion, J. B. Whitmore +14
Absorption line systems detected in quasar spectra can be used to compare the value of the fine-structure constant, α, measured today on Earth with its value in distant galaxies. I…
The CODEX-ESPRESSO experiment: cosmic dynamics, fundamental physics, planets and much more..
S. Cristiani, G. Avila, P. Bonifacio +36
CODEX, a high resolution, super-stable spectrograph to be fed by the E-ELT, the most powerful telescope ever conceived, will for the first time provide the possibility of directly…
UVES radial velocity accuracy from asteroid observations. Implications for the fine structure constant variability
P. Molaro, S. A. Levshakov, S. Monai +4
High resolution observations of the asteroids Iris and Juno have been performed by means of the UVES spectrograph at the ESO VLT to obtain the effective accurac y of the spectrogra…
A new measure of Delta alpha/alpha at redshift z = 1.84 from very high resolution spectra of Q1101-264
S. A. Levshakov, P. Molaro, S. Lopez +5
We probe the evolution of the fine-structure constant, alpha, with cosmic time. Accurate positions of the FeII lines 1608, 2382,and 2600 A are measured in the z = 1.84 absorption s…
The exotic chemical composition of the Sagittarius dwarf Spheroidal galaxy
L. Sbordone, P. Bonifacio, R. Buonanno +3
The Sagittarius dwarf Spheroidal galaxy is the nearest neighbor of the Milky Way. Moving along a short period quasi-polar orbit within the Halo, it is being destroyed by the tidal…
