Discovery of ADC absorption in the LMXB XB 1323-619 with XMM-Newton
Church, M. J.; Reed, D.; Dotani, T. +2 more
In our observation of the LMXB XB 1323-619 made with XMM-Newton in January 2003, a number of absorption lines were discovered, notably at 6.70 and 6.98 keV which we identify with scattering by high ionization state ions Fe XXV and Fe XXVI. Curve of growth analysis provided a consistent solution for collisional ionization for a plasma temperature k…
Flare diagnostics from loop modeling of a stellar flare observed with XMM-Newton
Reale, Fabio
XMM-Newton data of an X-ray flare observed on Proxima Centauri provide detailed and challenging constraints for flare modeling. The comparison of the data with the results of time-dependent hydrodynamic loop modeling of this flare allows us to constrain not only the loop morphology, but also the details of the heating function. The results show th…
INTEGRAL observation of the Crab pulsar
Cusumano, G.; Foschini, L.; Di Cocco, G. +5 more
In this paper, we present the timing and spectral analysis of several observations of the Crab pulsar with INTEGRAL. All these observations, when summed together provide an high-statistics data set which can be used for accurate phase resolved spectroscopy of the pulsed emission over the energy range 3 350 keV. In particular, we present the light …

HIPPARCOS Astrometric Observations of Symbiotic Stars
Badiali, M.; Cardini, D.; Emanuele, A. +1 more
The Hipparcos astrometric satellite has observed a number of symbiotic stars which are also known for being mapped at radio wavelengths. The radio emission generally arises from matter ejected by the binary system, which is made visible by the ionizing radiation of the system's hot component.
Hipparcos has provided the astrometric position (w…An atlas of solar events: 1996 2005
Auchère, F.; Artzner, G.; Delaboudinière, J. P. +1 more
Coronal mass ejections (CMEs) are observed in the plane of the sky in coronographic images. As the solar surface is masked by an occulting disk it is not clear whether halo CMEs are directed towards or away from the Earth. Observations of the solar corona on the solar disk by the extreme ultraviolet imaging telescope (EIT) on board the Solar Helio…

Observation of Continuum Radiation Close to the Plasmapause: Evidence for Small Scale Sources
Grimald, S.; Canu, P.; Décréau, P. +1 more
We briefly present observations of nonthermal continuum (NTC) radiations obtained close to the sources at the plasmapause by the Whisper instruments on Cluster. The examples considered illustrate the variety of the characteristics of the NTC such as the overall bandwidth of the emissions. The omnipresent multiple narrow bandwidth components are fu…
XMM-Newton observation of a dust echo and X-ray flash in GRB 031203
Vaughan, S.; Watson, D.; O'Brien, P. T. +4 more
We present XMM-Newton observations of the X-ray afterglow of GRB 031203, approximately 6 h after the initial burst detection by Integral. At z = 0.105, GRB 031203 is one of the least luminous γ-ray bursts, with an equivalent isotropic γ-ray energy of ∼3 × 10 49 ergs. The XMM-Newton images reveal an expanding X-ray halo around GRB 031203…
