EURONEAR - The European Near Earth Asteroid Research is a project initiated recently by a small team presently based in France, Romania, and South Africa. It envisions to build a coordinated network which will follow-up and recover Potentially Hazardous Asteroids (PHAs) and Near Earth Asteroids (NEAs), using time available at 1m class telescopes in

Hera provides a robust and cost-effective means to perform a planetary defense validation test with a solid balance between risk and innovation. In the frame of the AIDA collaboration, Hera contributes to a truly international planetary defense initiative. It will bring completely new knowledge and insights on asteroid science that will be of great

The relation between the Evershed flow and moving magnetic features (MMFs) is studied using high-cadence, simultaneous spectropolarimetric measurements of a sunspot in visible (630.2 nm) and near-infrared (1565 nm) lines. Doppler velocities, magnetograms, and total linear polarization maps are calculated from the observed Stokes profiles. We follow

THE active nuclei of Seyfert 1 galaxies are characterized by a small (˜0.03 pc) region of intense broad emission lines, indicative of gas moving at extremely high velocities and ionized by a non-thermal radiation field. These spectral features are usually explained by invoking the presence of a central supermassive black hole. Here we present two

We present high time resolution ULTRACAM optical and NOTCam infrared observations of the edge-on black hole X-ray transient Swift J1357.2-0933. Our data taken in 2012 and 2013 show the system to be at its pre-outburst magnitude and so the system is in quiescence. In contrast to other X-ray transients, the quiescent light curves of Swift J1357.2
