X-ray to UV Variability Correlation in MCG-6-30-15
P. Arevalo, I. Papadakis, B. Kuhlbrodt +1
We used a ~300 ks long XMM-Newton observation of the Seyfert 1 galaxy MCG-6-30-15 to study the correlation between the 0.2-10 keV X-ray and the 3000-4000 A bands. We found a signif…
Detection of the white dwarf and the secondary star in the new SU UMa dwarf nova HS 2219+1824
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +4
We report the discovery of a new, non-eclipsing SU UMa-type dwarf nova, HS 2219+1824. Photometry obtained in quiescence (V ~ 17.5) reveals a double-humped light curve from which we…
Efficient Searches for r-Process-Enhanced, Metal-Poor Stars
T. C. Beers, P. S. Barklem, N. Christlieb +1
Neutron-capture-enhanced, metal-poor stars are of central importance to developing an understanding of the operation of the r-process in the early Galaxy, thought to be responsible…
Carbon-Enhanced Metal-Poor Stars in the Early Galaxy
B. Marsteller, T. C. Beers, S. Rossi +3
Very metal-deficient stars that exhibit enhancements of their carbon abundances are of crucial importance for understanding a number of issues -- the nature of stellar evolution am…
Decomposition of AGN host galaxy images
B. Kuhlbrodt, L. Wisotzki, K. Jahnke
We describe an algorithm to decompose deep images of Active Galactic Nuclei into host galaxy and nuclear components. Currently supported are three galaxy models: A de-Vaucouleurs s…
