The Observatorio Astrofísico de Javalambre (OAJ) is a new Spanish astronomical facility particularly designed for carrying out large sky surveys. The OAJ is mainly motivated by the development of J-PAS, the Javalambre- PAU Astrophysical Survey, an unprecedented astronomical survey that aims to observe 8500 deg2 of the sky with a set of 54 optical

Aims: Occultations of bright stars by planets provide information on the state of their atmospheres. An occultation of the bright star 45 Capricornii (HIP 107302) by Jupiter occurred on the night of 3/4 August 2009. Methods: The event was observed at multiple sites in Europe, Africa and South America and with instruments ranging in aperture from 0

We present narrowband images and [Nii]lambda 658.3 nm spectra, obtained under sub-arcsec seeing conditions, of the extended nebulae around the symbiotic Miras He 2-147, HM Sge, and V1016 Cyg. The main results of this study are: The nebula around He 2-147 is a ring expanding with a velocity of ~ 100 km s(-1) which is inclined at ~ 55(deg) to the

We present intermediate resolution spectroscopy of the dwarf nova CY UMa in quiescence. From the radial velocities of the Hα emission, we derive an orbital period of 0.067 95+/-8x10^-5 d, which disagrees with previous photometric estimates. We also constrain the system parameters. The core of the Hα emission seems to be dominated by a component

Near-Earth asteroid (162173) 1999 JU3 (henceforth JU3) is a potentially hazardous asteroid and the target of the Japanese Aerospace Exploration Agency's Hayabusa-2 sample return mission. JU3 is also a backup target for two other sample return missions: NASA's OSIRIS-REx and the European Space Agency's Marco Polo-R. We use dynamical information to

We combine new (NGC 1275, NGC 4151, and NGC 5506) and previously published (Cygnus A, Mrk 231, and NGC 1068) sub-arcsecond resolution mid-infrared (MIR; 8-13 μm) imaging- and spectro-polarimetric observations of six Seyfert galaxies using CanariCam on the 10.4-m Gran Telescopio CANARIAS. These observations reveal a diverse set of physical processes
