We present new number density and surface brightness profiles for the globular cluster M92 (NGC 6341). These profiles are calculated from optical images collected with the CCD mosaic camera MegaCam at the Canada-France-Hawaii Telescope and with the Advanced Camera for Surveys on the Hubble Space Telescope. The ground-based data were supplemented

Context. Primitive asteroids contain complex organic material and ices relevant to the origin of life on Earth. These types of asteroids are the target of several sample-return missions to be launched in the next years. 1999 JU3 is the target of the Japanese Aerospace Exploration Agency's Hayabusa 2 mission. Aims: 1999 JU3 has been previously

We calibrated the absolute magnitudes M V , M J , M_{Ks} and M g of red clump stars in terms of colours. M V and M g are strongly dependent on colour, while the dependence of M J and M_{Ks} on colour is rather weak. The calibration of the absolute magnitudes M V and M_{Ks} is tested on 101 RC stars in the field SA 141. The Galactic model parameters

Tadpole galaxies, with a bright peripheral clump on a faint tail, are morphological types unusual in the nearby universe but very common early on. Low mass local tadpoles were identified and studied photometrically in a previous work, which we complete here analyzing their chemical and dynamical properties. We measure Hα velocity curves of seven

The WFCAM Transit Survey (WTS) is a near-infrared transit survey running on the United Kingdom Infrared Telescope (UKIRT). We conduct Monte Carlo transit injection and detection simulations for short period (

High resolution spectra are used to analyze the galactic kinematics and distribution of a sample of planetary nebulae with [WR] and `wel' central star ([WR]PN and WLPN). The circular and peculiar velocities, (V_pec), of the objects were derived. The results are: (a) [WR]PNe are distributed mainly in the galactic disk and they are more concentrated
