We present an analysis of the HD planetary system based on a photometric transit dataset and radial velocities obtained on 3 December 2007. We also present...

This table contains the photometric time serie obtained for a series of transits of the planet HD 17156b. The first column gives the date as Barycentric Julian...

The tables represent the results of the frequency analysis of various models: under assumption of stable, long-lasting and independent frequencies with constant...

We present high-resolution spectroscopy of HD 306414, optical counterpart to the hard X-ray transient IGR J11215-5952, an object belonging to the class of...

We compared the results from SigSpec and from the iterative-sine-wave fitting, considering an error range of 0.005d-1 in frequency (i.e., a width 3.4 times...

We present the results of a spectroscopic campaign on the early-type double-lined binary HD 64315. The radial velocity curve was calculated using a fit to model...

Most of the known transiting extrasolar planets orbit slowly rotating F, G or K stars. In here we report on the detection of a transiting planet orbiting the...

HST multi-epoch images and VLT integral-field, high resolution spectroscopy allowed us a robust determination of the 3-D geometry and orientation of the nebula...
