A sample of galaxies characterized by a low surface brightness disk has dynamically studied using, as tracer, the stellar component. The kinematical data, taken along the major and minor axis, extend well within the disk region. The stellar kinematics is more regular and symmetric than the ionized-gas kinematics. Moreover, when comparing the

Accretion onto a supermassive black hole (BH) is the most viable explanation for the huge emitted luminosity in active galaxies. Nowadays a wealth of observations have shown the presence of a BH in many nearby inactive bulges, suggesting that all massive spheroids harbor a BH. Moreover, at low redshift, fundamental correlations have been found

To optimise the science results of the asteroseismic part of the CoRoT satellite mission a complementary simultaneous ground-based observational campaign is organised for selected CoRoT targets. The observations include both high-resolution spectroscopic and multicolour photometric data. We present the preliminary results of the analysis of the

Context: The chronology of bulge and disk formation is a major unsolved issue in galaxy formation, which impacts on our global understanding of the Hubble sequence. Aims: We analyse colours of the nuclear regions of intermediate redshift disk galaxies, with the aim of obtaining empirical information of relative ages of bulges and disks at 0.1 z 1

In this paper we describe a methodology to be used for the automated analysis of the spectroscopic contents of the GAUDI archive. We perform chi-square minimisation in the 5000-5200 Å spectral window to infer the atmospheric parameters and their random internal uncertainties. Effective temperatures are anchored using a zero-point correction into

We stand on the threshold of a critical expansion of asteroseismology of Sun-like stars, the study of stellar interiors by observation and analysis of their global acoustic modes of oscillation. The Sun-like oscillations give a very rich spectrum allowing the internal structure and dynamics to be probed down into the stellar cores to very high
