The planetary system discovered around the young A-type HR8799 provides a unique laboratory to: a) test planet formation theories, b) probe the diversity of system architectures at these separations, and c) perform comparative (exo)planetology. We pr

We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars:

Although very successful (more than 350 planets discovered up to now), indirect methods for extrasolar planet detection (Radial velocities, transits) are sensitive to planets quite close to their hosts. Moreover, accurate studies of the planet charac

Several years of coordinated multifrequency observations of the dwarf nova SS Cygni have been performed in order to study the accretion behaviour of this system in particular, and in general to clarify this crucial problem for the cataclysmic variabl

SS Cygni: The mass accretion rate behaviour in quiescence and in outburst

Autor: R. Lombardi, Franco Giovannelli, R. U. Claudi, S. Gaudenzi

From the HeII λ1640 emission line equivalent width values in all good available IUE low resolution spectra, we have deduced the correspondent mass accretion rate values Ṁ for SS Cygni, using the optically thick boundary-layer model by Patterson an
