This paper was withdrawn due to a misidentification of the source.
PopStar: A new grid of Evolutionary Synthesis Models in the Virtual Observatory
Marisa García-Vargas, Mercedes Mollá, Alessandro Bressan +1
We present a new set of theoretical evolutionary synthesis models, PopStar. This grid of Single Stellar Populations covers a wide range in both, age and metallicity. The models use…
A new grid of evolutionary synthesis models
M. Mollá, M. L. García-Vargas, Alessandro Bressan +1
We present new evolutionary synthesis models for Single Stellar Populations covering a wide range in age and metallicity. The most important difference with existing models is the…
The role of the star formation on the nitrogen abundance evolution
M. Mollá, J. M. Vílchez, A. I. Díaz +1
We analyze the evolution of nitrogen resulting from a set of spiral and irregular galaxy models computed for a large number of input mass radial distributions and with various star…
The X-ray view of the ionization cone in NGC5252
Matteo Guainazzi, Stefano Bianchi, Massimo Cappi +2
We present the results of a Chandra soft X-ray observation of the spectacular ionization cone in the nearby Seyfert 2 galaxy NGC 5252. As almost invariably observed in obscured AGN…
Spectral Analysis of Super Soft X-ray Sources: V4743 Sagittarii
Thomas Rauch, Marina Orio, R. Gonzales-Riestra +1
Half a year after its outburst, the nova V4743 Sgr evolved into the brightest super-soft X-ray source in the sky with a flux maximum around 30A, exhibiting resonance lines of C V,…
