A Photometric System for Metallicity Mapping in Galaxies
A new photometric system suitable for deep, precise and quick metallicity mapping in galaxies is proposed. We find a linear correlation between our metallicity...
A pile of new Planetary Nebulae in the Galactic Plane
The INT photometric H-alpha Survey (IPHAS; http://www.iphas.org) is now near completion. A band of 10 degrees along the Northern Galactic Plane is being imaged...
A Pilot Survey of Stellar Tidal Streams in Nearby Spiral Galaxies
Within the hierarchical framework for galaxy formation, merging and tidal interactions are expected to shape large galaxies to this day. While major mergers are...
A Pipeline for the Analysis of APOGEE Spectra Based on Equivalent Widths
The Apache Point Galactic Evolution Experiment (APOGEE) forms part of the third Sloan Digital Sky Survey and has obtained high resolution, high signal-to-noise...
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...
Most of the known transiting extrasolar planets orbit slowly rotating F, G or K stars. In here we report on the detection of a transiting planet orbiting the...
Up to now our knowledge on frequency of planets of stars that are more massive than the sun is rather limited. In here we present the discovery of a planet...
10199 Chariklo is the largest Centaur so far known. To investigate its surface composition and possible surface variations, spectroscopic observations have been...
