Earth based multichannel photometry of integral sunlight has been obtained at Izaña (Tenerife) during 1984 - 1986. Power spectra of the solar luminosity...

Earthshine is sunlight that has been reflected from the dayside Earth onto the dark side of the Moon and back again to Earth. In recent times, there has been a...

Terrestrial albedo data are important for climate model studies because of the impor- tance albedo has on the net radiation budget of the Earth. Direct...

EMIR Associate Science Team (EAST) is a scientific group in charge of developing an observing program complementary to that of GOYA, which might serve as a...

MAGIC is a stereoscopic system of two Imaging Atmospheric Cherenkov Telescopes operating in the very high energy (VHE) range from about 50 GeV to over 50 TeV...

We present echelle spectroscopy in the 3550 to 7010 A range for two positions of the Orion Nebula. The data were obtained with the 2.1-m telescope at...

Echo Tomography is a powerful technique which enables us to probe the accretion geometry in active LMXBs by studying reprocessing of X-rays into UV/optical...

We present preliminary results of a simultaneous X-ray/optical campaign of the proto-typical LMXB Sco X-1 at 1-10 Hz time resolution. Lightcurves of the high...

The 11408 targets observed by CoRoT were selected using the information gathered in the database Exo-Dat (Deleuil et al. 2009AJ....138..649D; Meunier et al...
