In helioseismic inversions, the number of independent pieces of information that a mode set contains is much less than the actual number of modes. This is due...

TrES-Her0-07621 is a recently discovered detached M Dwarf eclipsing binary system. We present some follow-up observations of this system including new minima...

We describe the Very Small Array (VSA) and review the recent results on the angular power spectrum of the Cosmic Microwave Background (CMB) obtained in the Ka...

Two research paths are described to obtain better understanding of the origin of global solar activity. First, observations with a multichannel resonant...

Open Clusters are dynamically-bound groups of stars that formed from the same giant molecular cloud, having a similar age and bulk chemical composition. Open...

An asteroid family is a group of asteroids with similar orbital proper elements (e.g., Nesvorný et al. 2005), which could be fragments formed by large impact...

We have observed Arp 270 using the GHαFaS Fabry-Perot spectrometer on the 4.2m William Herschel Telescope (La Palma). In the edge-on companion we detect a...

We present a study of the internal kinematics and stellar populations of early-type galaxies in the Fornax cluster based on integral-field spectroscopic...
