XMM-Newton observation of the deep minimum state of PG 2112+059: A spectrum dominated by reflection from the accretion disk?
N. Schartel, P. M. Rodriguez-Pascual, M. Santos-Lleo +5
We analyse a 75ks XMM-Newton observation of PG 2112+059 performed in November 2005 and compare it with a 15ks XMM-Newton observation taken in May 2003. PG 2112+059 was found in a d…
Detailed chemical composition of Galactic Cepheids. A determination of the Galactic abundance gradient in the 8-12 kpc region
B. Lemasle, P. Francois, G. Bono +3
The recent introduction of high resolution/large spectral range spectrographs provided the opportunity to investigate in detail the chemical composition of classical Cepheids. This…
The Distance to NGC 5904 (M 5) via the Subdwarfs Main Sequence Fitting Method
Vincenzo Testa, Alessandro Chieffi, Marco Limongi +2
We present a determination of the distance modulus of the globular cluster NGC 5904 (M 5), obtained by means of the subdwarf main-sequence fitting on the (V,V-I) color-magnitude di…
Broad band properties of medium and low Lx/Lb Early Type Galaxies
G. Trinchieri, S. Pellegrini, A. Wolter +2
We have measured the spectral properties of five galaxies of low to intermediate Lx/Lb ratios with BeppoSAX and ASCA. A hard component (kT ~4-10 keV) is observed in all galaxies. I…
Observations of the Galactic Center Region with Beppo-Sax
L. Sidoli, S. Mereghetti
We are performing a survey of the Galactic Center region with the BeppoSAX satellite. Several known point sources are visible (including one at the position of SgrA*), as well as n…
BeppoSAX confirms extreme relativistic effects in the X-ray spectrum of MCG-6-30-15
M. Guainazzi, G. Matt, S. Molendi +8
We report the first simultaneous measure of the X-ray broadband (0.1--200 keV) continuum and of the iron K-alpha fluorescent line profile in the Seyfert 1 galaxy MCG-6-30-15. Our d…
