An analysis of photometric observations of binary Near-Earth asteroid (175706) 1996 FG3, taken from 1996 to 2012, gave a single solution for a quadratic drift of the mean anomaly of the satellite, 0.0 deg/yr^2, consistent with recent BYORP theory.

We present photometric time-series obtained by the TRAPPIST, Euler and VLT telescopes. (4 data files).

We present observations of a statistically-significant number of Jupiter-family cometary nuclei as part of SEPPCoN (Survey of the Ensemble Physical Properties of Cometary Nuclei). We present preliminary results on distributions of albedos and shapes.

TYC 4110-01037-1 has a low-mass stellar companion, whose small mass ratio and short orbital period are atypical among binary systems with solar-like (T eff

We study the magnetic field and the umbral intensity of sunspots for the period 1999 to 2011. We analyze full Stokes spectra of 183 spots observed with the Tenerife Infrared Polarimeter at the German Vacuum Tower Telescope on Tenerife. We derive the magnetic field strength in the umbra from the Zeeman splitting of a near-infrared spectral line

Aims: We study the variation in the magnetic field strength and the umbral intensity of sunspots during the declining phase of the solar cycle No. 23 and in the beginning of cycle No. 24. Methods: We analyze a sample of 183 sunspots observed from 1999 until 2011 with the Tenerife Infrared Polarimeter (TIP) at the German Vacuum Tower Telescope (VTT)
