Plaskett's Star: Analysis of the CoRoT photometric data
Plaskett's Star the CoRoT photometric data
2011/1/10
The SRa02 of the CoRoT space mission for Asteroseismology was partly devoted to stars belonging to the Mon OB2 association. An intense monitoring was performed on Plaskett's Star (HD47129) and the unp...
The chemical abundances of metal-poor stars are an excellent test bed by which to set new constraints on models of neutron-capture processes at low metallicity. Some r-process-rich (hereafter r-rich) ...
Constraints on cosmic-ray propagation models from a global Bayesian analysis
astroparticle physics—diffusion—methods statistical—cosmic rays—ISM general—Galaxy: general
2010/11/9
Research in many areas of modern physics such as, e.g., indirect searches for dark matter and particle acceleration in SNR shocks, rely heavily on studies of cosmic rays (CRs) and associated diffuse e...

A convergence of astrophysical observations indicates that 80% of the matter in the universe is in the form of non-baryonic, non-luminous dark matter [1]. Weakly Interacting Massive Particles (WIMPs)...
Genetic algorithms and the analysis of SnIa data
Genetic algorithms the analysis of SnIa data
2010/11/12
The Genetic Algorithm is a heuristic that can be used to produce model independent solutions to an optimization problem, thus making it ideal for use in cosmology and more specifically in the analysis...
An analysis of the blue straggler population in the Sgr dSph globular cluster Arp 2
open clusters and associations general - open clusters and associations individual (Arp 2) - binaries
2010/11/12
We present and discuss new BVI CCD photometry in the field of the globular cluster Arp 2,
which is considered a member of the Sagittarius Dwarf Spheroidal Galaxy. The main goal
of this investigation...
Optical multiband surface photometry of a sample of Seyfert galaxies. I. Large-scale morphology and local environment analysis of matched Seyfert and inactive galaxy samples
galaxies Seyfert – galaxies structure – techniques image processing – techniques photometric
2010/11/12
Context. Parallel analysis of the large-scale morphology and local environment of matched active and control galaxy samples plays an important role in studies of the fueling of active galactic nuclei.
Helioseismic Ring Analysis of CME Source Regions
Sun coronal mass ejections oscillations magnetic field
2010/9/16
We apply the ring diagram technique to source regions of halo coronal mass ejections (CMEs) to study changes in acoustic mode parameters before, during, and after the onset of CMEs.We find that CME re...
