Detección de la estrella simbiótica Hen 2-87 en rayos X con XMM-Newton

Luna, G. J. M.; Nuñnez, N. E.

Symbiotic stars are interacting binary systems, where accretion, most of the times, occurs onto a white dwarf. Until recently only a couple of dozens of symbiotics were known to be X-ray emitters, with most of the emission having energies of less than about 2.00 keV. In the last decade, with the launch of modern X-ray satellites such as XMM-Newton…

Is there a Central Compact Object within G290.1--0.8?

Bocchino, F.; Combi, J. A.; García, F. +3 more

We study the central region of the supernova remnant (SNR) G290.1--0.8 in order to search for a possible compact stellar remnant associated to it. Our analysis of XMM-Newton and Chandra archival observations reveals three point-like sources. Two of them are hard X-ray sources, possibly Active Galactic Nuclei. The third one, located very close to t…
