Symbiotic stars in X-rays
(Edp Sciences S A, 2012-11-27)
Until recently, symbiotic binary systems in which a white dwarf accretes from a red giant were thought to be mainly a soft X-ray population. Here we describe the detection with the X-ray Telescope (XRT) on the Swift satellite ...
Symbiotic stars in X-rays. II. Faint sources detected with XMM-Newton and Chandra
(Edp Sciences, 2014-05)
We report the detection from four symbiotic stars that were not known to be X-ray sources. These four object show a β-type X-ray spectrum, that is, their spectra can be modeled with an absorbed optically thin thermal ...
SU Lyncis, a hard X-ray bright M giant: clues point to a large hidden population of symbiotic stars
(Oxford University Press, 2016-05-05)
Symbiotic star surveys have traditionally relied almost exclusively on low resolution optical spectroscopy. However, we can obtain a more reliable estimate of their total Galactic population by using all available signatures ...
Swift observations of the 2015 outburst of AG Peg - from slow nova to classical symbiotic outburst
(Oxford University Press, 2016-10)
Symbiotic stars often contain white dwarfs with quasi-steady shell burning on their surfaces. However, in most symbiotics, the origin of this burning is unclear. In symbiotic slow novae, however, it is linked to a past ...
Detection of X-rays from the jet-driving symbiotic star Hen 3-1341
(Edp Sciences, 2013-06)
Context. Hen 3-1341 is a symbiotic binary system consisting of a white dwarf and a red giant star that is one of about ten symbiotics that show hints of jets. The bipolar jets have been detected through displaced components ...
SU Lyn: Diagnosing the Boundary Layer with UV and Hard X-Ray Data
(IOP Publishing, 2018-08)
Symbiotic stars in which the symbiotic phenomenon is powered solely by accretion, often at an average rate that is higher than in cataclysmic variable stars, provide an important opportunity to diagnose boundary layers ...
Dramatic change in the boundary layer in the symbiotic recurrent nova T Coronae Borealis
(EDP Sciences, 2018-11)
A sudden increase in the rate at which material reaches the most internal part of an accretion disk, i.e., the boundary layer, can change its structure dramatically. We have witnessed such a change for the first time in ...
K-band spectroscopy of IGR J16358-4726 and IGR J16393-4643: two new symbiotic X-ray binaries
(2010)
Symbiotic X-ray Binaries (SyXBs) are a recently discovered subclass of Low Mass X-ray Binaries. Their growing number makes them an important evolutionary channel of X-ray Binaries. Our goal is to perform spectral analysis ...

Symbiotic stars in X-rays III. Suzaku observations
(Iop Publishing, 2016-06-07)
We describe the X-ray emission as observed by Suzaku from five symbiotic stars that we selected for deep Suzaku observations after their initial detection with ROSAT, ASCA, and Swift. We find that the X-ray spectra of all ...
