GX 339—4: the distance, state transitions, hysteresis and spectral correlations
We study X-ray and variability and distance of GX 339–4. We derive the distance of > 7 kpc, based on recent determination of the binary parameters. We study data from the ASM aboard Ginga, the BATSEExpand
A catalogue of symbiotic stars
We present a new catalogue of symbiotic stars. In our list we include 188 symbiotic stars as well as 30 objects suspected of being symbiotic. For each star, we present basic observational material:Expand
Broad-band X-ray/γ-ray spectra and binary parameters of GX 339–4 and their astrophysical implications
We present X-ray/γ-ray spectra of the binary GX 339–4 observed in the hard state simultaneously by Ginga  and CGRO  OSSE during an outburst in 1991 September. The Ginga  X-ray spectra are wellExpand
Spectroscopic orbits and variations of RS Oph
The aims of our study are to improve the orbital elements of the giant and to derive the spectroscopic orbit for the white dwarf companion. Spectral variations related to the 2006 outburst are alsoExpand
Cyg X-3: a low-mass black hole or a neutron star.
Cyg X-3 is a highly interesting accreting X-ray binary, emitting from the radio to high-energy gamma-rays. It consists of a compact object wind-fed by a Wolf-Rayet (WR) star, but the masses of theExpand
New binary parameters for the symbiotic recurrent nova T Coronae Borealis
The amplitude of the ellipsoidal variability, the mass function and the evolutionary limits on the component masses have been used to constrain the binary system parameters of T Coronae Borealis.Expand
Evolution of the symbiotic binary system AG Pegasi - The slowest classical nova eruption ever recorded
We present an analysis of new and existing photometric and spectroscopic observations of the ongoing eruption in the symbiotic star AG Pegasi, showing that this binary has evolved considerably sinceExpand
A measurement of the broadband spectrum of XTE J1118+480 with BeppoSAX and its astrophysical implications
We report on results of a Target-of-Opportunity observation of the X-ray transient XTE J1118+480 performed on 2000 April 14-15 with the Narrow Field Instruments (0.1-200 keV) of the BeppoSAXExpand
Proper-motion age dating of the progeny of Nova Scorpii AD 1437
The recovery of the binary star underlying the classical nova eruption of 11 March AD 1437 is reported, and its age is independently confirmed by proper-motion dating to conclude that many old novae become dwarf novae for part of the millennia between successive nova eruptions. Expand
The spectroscopic orbit and the geometry of R Aquarii
Context. R Aqr is one of the closest symbiotic binaries and the only D-type system with radial velocity data suitable for orbital parameter estimation. Aims. The aims of our study are to derive aExpand
