Mining SDSS in search of Multiple Populations in Globular Clusters
Mining SDSS Multiple Populations Globular Clusters
2011/1/10
Several recent studies have reported the detection of an anomalous color spread along the red giant branch (RGB) of some globular clusters (GC) that appears only when color indices including a near ul...
A Population of Very-Hot Super-Earths in Multiple-Planet Systems Should be Uncovered by Kepler
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
We simulate a Kepler-like observation of a theoretical exoplanet population and we show that the observed orbital period distribution of the Kepler giant planet candidates is best matched by an averag...
Spectral imaging of the Sagittarius B2 region in multiple 7-mm molecular lines
Galaxy Astrophysics (astro-ph.GA)
2010/12/29
We have undertaken a spectral-line imaging survey of a 6 x 6 arcmin^2 area around Sgr B2 near the centre of the Galaxy, in the range from 30 to 50 GHz, using the Mopra telescope. The spatial resolutio...
CCD MEASUREMENTS OF DOUBLE AND MULTIPLE STARS AT NAO ROZHEN. IV
binaries visual the Bulgarian National Astronomical Observatory
2010/10/29
Using the 2 m telescope of the Bulgarian National Astronomical Observatory at Rozhen observations of 30 double or multiple stars were carried out during two half nights on July 20 and 21, 2009. This i...
Multiple Weak Deflections in Galaxy-Galaxy Lensing
dark matter galaxies halos gravitational lensing
2010/3/9
The frequency and effects of multiple weak deflections in galaxy-galaxy lensing are investigated via Monte Carlo simulations. The lenses in the simulations are galaxies with known redshifts and known ...
