The mixing of the quasifission component to the fissionlike cross section causes ambiguity in the quantitative estimation of the complete fusion cross section from the observed angular and mass distributions of the binary products. We show that the partial cross section of quasifission component of binary fragments covers the whole range of the

The theory of radiatively-driven winds successfully explains the key points of the stellar winds of hot massive stars. However, it has been recently found that some O- and B-type stars do not exhibit as strong wind as predicted by theory. In this work we explain the main issues concerning this topic. We also describe our analysis of the UV spectra

A description of the Spanish contribution to the Marco Polo mission and of the mission itself is presented. Marco Polo is a joint European-Japanese mission of sample return from a Near Earth Object (NEO). Submitted to ESA on July 2007 in the framework of the Cosmic Vision 2015-2025, Marco Polo passed the first evaluation process on October 2007

Waves connect all the layers of the Sun, from its interior to the upper atmosphere. It is becoming clear now the important role of magnetic field on the wave propagation. Magnetic field modifies propagation speed of waves, thus affecting the conclusions of helioseismological studies. It can change the direction of the wave propagation, help

Solar gravity (g) modes propagate within the radiative part of the solar interior and are highly sensitive to the physical conditions of the solar core. They would represent the best tool to infer the structure and the dynamics of the radiative interior, in particular the core, if they were properly detected and characterized. Although individual

We present SAURON stellar kinematical analysis for four double-barred early-type galaxies: NGC 2859, NGC 3941, NGC 4725 and NGC 5850. The presence of the inner bar is not evident from the radial velocity, but it appears to have an important effect in the stellar velocity dispersion maps: we find two σ-hollows of amplitudes between 10 and 40 km s- 1
