This paper presents 3600—5400Å integrated spectra of 19 globular clusters (or candidates) projected on the central regions of M 31, r ≤ 5.3 ′ (≈1.2 kpc). We check the cluster nature of these objects, and derive their ages, metallicities and reddenings. From the initial sample , 16 objects turn out to be true star clusters, two are Galactic dwarf stars, and one is a high redshift background gala...

We evaluate widths and shifts of pionic atoms using a theoretical microscopical potential in which the pion decay constant fπ is changed by the medium fπ(ρ) one, predicted by many different approaches. We show that the results obtained for shifts and widths are worse than if the correction is not implemented. Only in the case where one implements the modification in the real part of the s−wave ...

The dynamical parameters conventionally used to specify the orbit of a test particle in Kerr spacetime are the energy E, the axial component of the angular momentum, L z , and Carter's constant Q. These parameters are obtained by solving the Hamilton-Jacobi equation for the dynamical problem of geodesic motion. Employing the action-angle variable formalism, on the other hand, yields a different...
