Periods and damping times of quasi-mode fundamental kink oscillations have been computed for non-uniform cylindrical models of coronal loops. The radial inhomogeneity length-scale, the density contrast and the internal Alfvén velocity are three equilibrium quantities that determine the theoretical values of the period and damping times in 1-D

Ground-based wide-field surveys for nearby transiting gas giants are yielding far fewer true planets than astrophysical false positives, some of which are difficult to reject. Recent experience has highlighted the need for careful analysis to eliminate astronomical systems in which light from a faint eclipsing binary is blended with that from a

We analyse the problem of parameter estimation for compact binary systems that could be detected by ground-based gravitational wave detectors. So far, this problem has only been dealt with for the inspiral and the ringdown phases separately. In this paper, we combine the information from both signals, and we study the improvement in parameter

We present ground-based B and R-band color-magnitude diagrams (CMDs) of unprecedented depth for twelve fields in the Small Magellanic Cloud (SMC). They reach the oldest main-sequence turnoffs and cover a wide range of galactocentric distances up to ˜4° from the SMC center, and are located at different position angles. A picture of the stellar

We present a new catalog of absolute nuclear magnitudes of Jupiter family (JF) comets, which is an updated version of our previous catalog [Tancredi, G., Fernández, J.A., Rickman, H., Licandro, J., 2000. Astron. Astrophys. Suppl. Ser. 146, 73 90]. From the new catalog we find a linear cumulative luminosity function (CLF) of slope 0.54±0.05 for JF

We have used the Rayner and Best smooth tests of goodness-of-fit to study the Gaussianity of the Very Small Array (VSA) data. These tests are designed to be sensitive to the presence of `smooth' deviations from a given distribution, and are applied to the data transformed into normalized signal-to-noise eigenmodes. In a previous work, they have
