V5116 Sgr, an Eclipsing Supersoft Post-Outburst Nova?
Gloria Sala, Margarita Hernanz, Carlo Ferri +1
V5116 Sgr (Nova Sgr 2005 No. 2), discovered on 2005 July 4, was observed with XMM-Newton in March 2007, 20 months after the optical outburst. The X-ray spectrum shows that the nova…
GRI: focusing on the evolving violent Universe
Jürgen Knödlseder, Peter Von Ballmoos, Filippo Frontera +4
The Gamma-Ray Imager (GRI) is a novel mission concept that will provide an unprecedented sensitivity leap in the soft gamma-ray domain by using for the first time a focusing lens b…
XMM-Newton observations of Nova Sgr 1998
M. Hernanz, G. Sala
We report on X-ray observations of Nova Sagittarius 1998 (V4633 Sgr), performed with XMM-Newton at three different epochs, 934, 1083 and 1265 days after discovery. The nova was det…
A Chandra LETGS observation of V4743 Sagittarius: A Super Soft X-ray Source and a Violently Variable Light Curve
J. -U. Ness, S. Starrfield, V. Burwitz +13
V4743 Sgr (Nova Sgr 2002 No. 3) was discovered on 20 September 2002. We obtained a 5ks ACIS-S spectrum in November 2002 and found that the nova was faint in X-rays. We then obtaine…
Possibility of the detection of classical novae with the shield of the INTEGRAL-spectrometer SPI
P. Jean, J. Gomez-Gomar, M. Hernanz +7
The shield of the INTEGRAL spectrometer provides a large detection area with a wide field-of-view. Calculations have been performed to check whether the temporal analysis of the co…
The halo white dwarf population
J. Isern, E. Garcia-Berro, M. Hernanz +2
Halo white dwarfs can provide important information about the properties and evolution of the galactic halo. In this paper we compute, assuming a standard IMF and updated models of…
