Although more than a thousand transiting extrasolar planets have been discovered, only very few of them orbit stars that are more massive than the Sun. The discovery of such planets is interesting, because they have formed in disks that are more massive but had a shorter life time than those of solar-like stars. Studies of planets more massive than

10199 Chariklo is the largest Centaur so far known. To investigate its surface composition and possible surface variations, spectroscopic observations have been carried out at the largest available telescopes. We obtained near-infrared spectra at ESO-VLT (Cerro Paranal, Chile) and TNG (La Palma, Spain) on April 2001 and March 2002, respectively

A periodic signal of high nominal significance (99.95%) is found in the light curve of OJ 287 in observations taken with the Prime Focus Camera Unit on the 2.5 m Isaac Newton Telescope on two nights in March April 1987. No such periodicity is seen in the light curve of the simultaneously observed reference star. A null test involving observations

This paper announces the release at CDS of a substantial set of point sources detected by the DENIS project. DENIS is the first astronomical survey of the Southern sky in two near-infrared bands (J at 1.25 mu m, and K_s at 2.15 mu m) and one optical band (Gunn-i at 0.82 mu m), conducted by a European consortium, using the 1m telescope at ESO, La
