We present an algorithm (MEAD, for `Mapping Extinction Against Distance') which will determine intrinsic (r' - i') colour, extinction, and distance for early-A to K4 stars extracted from the IPHAS r'/i'/Hα photometric data base. These data can be binned up to map extinction in three dimensions across the northern Galactic plane. The large size of

Context: ω Centauri is the most well studied Galactic Globular Cluster because of its numerous puzzling features: significant dispersion in metallicity, multiple populations, triple main-sequence, horizontal branch morphology, He-rich population(s), and extended star-formation history. Intensive spectroscopic follow-up observing campaigns targeting

We present new global mass functions for a large number of clusters from the ACS Survey of Galactic Globular Clusters and find that the majority of the mass functions follow power-law behavior from the main sequence turnoff (at approximately 0.7 solar masses) down to our completeness limit (at approximately 0.3 solar masses). Comparing the mass

The European Near Earth Asteroids Research (EURONEAR) is a project which envisions to establish a coordinated network to follow-up, recover and discover Near Earth Asteroids (NEAs), Potentialy Hazardous Asteroids (PHAs) and Virtual Impactors (VIs). Within this network, more than 100 objects have been observed during the first two years using 1m

Lenorzer et al. introduce ratios of hydrogen infrared recombination lines as a diagnostic tool to constrain the spatial distribution and physical condition of circumstellar material around hot massive stars. They demonstrate that the observed line flux ratios Hu14/Brα and Hu14/Pfγ from different types of objects associated with circumstellar
