An X-ray Jet from a White Dwarf – Detection of the Collimated Outflow from Ch Cygni with Chandra
نویسندگان
چکیده
Most symbiotic stars consist of a white dwarf accreting material from the wind of a red giant. A growing number of these objects have been found to produce jets. Analysis of archival Chandra data of the symbiotic system CH Cygni reveals faint extended emission to the south, aligned with the optical and radio jets seen in earlier HST and VLA observations. CH Cygni thus contains only the second known white dwarf with an X-ray jet, after R Aquarii. Subject headings: binaries: symbiotic — stars: individual (CH Cygni) — stars: winds, outflows — white dwarfs — X-rays: general

The transient jet of the galactic supersoft X - ray source RX J 0925 . 7 - 4758 ?
We report the discovery of a transient jet in the supersoft X-ray source RX J0925.7-4758. The jet was observed in the Hα line during a single night in June 1997 and had disappeared one day later. RX J0925.7-4758 is the third supersoft source to exhibit collimated outflows. The peak jet velocity of 5,200 km s−1, strongly argues in favour of a white dwarf in RX J0925.7-4758. Simple modelling of t...
متن کاملAn Apparent Hard X-ray Decline of CH Cygni
CH Cygni is a symbiotic star consisting of an M giant and an accreting white dwarf, which is known to be a highly variable X-ray source with a complex, two-component, spectra. Here we report on two Suzaku observations of CH Cyg, taken in 2006 January and May, during which the system was seen to be in a soft X-ray bright, hard X-ray faint state. Based on the extraordinary strength of the 6.4 keV...
متن کاملBroad P Cygni X - ray Lines from Circinus X -
Chandra High Energy Transmission Grating Spectrometer (HETGS) observations of the extremely luminous and violent X-ray binary Cir X-1 reveal many X-ray emission lines showing broad P Cygni profiles. These are from H-like and He-like ions of Ne, Mg, Si, S, Ar, and Fe. The lines originate in a high-velocity (up to 2000 km s) outflow, which may be an accretion disk wind. Cir X-1 has a radio jet, a...
متن کاملThe 2015 Decay of the Black Hole X-ray Binary V404 Cygni: Robust Disk-jet Coupling and a Sharp Transition into Quiescence
We present simultaneous X-ray and radio observations of the black hole X-ray binary V404 Cygni at the end of its 2015 outburst. From 2015 July 11–August 5 we monitored V404 Cygni with Chandra, Swift, and NuSTAR in the X-ray, and with the Karl G. Jansky Very Large Array and the Very Long Baseline Array in the radio, spanning a range of luminosities that were poorly covered during its previous ou...
متن کاملJet Breaks in Short Gamma-ray Bursts. I: the Uncollimated Afterglow of Grb050724
We report the results of the Chandra observations of the Swift-discovered short Gamma-Ray Burst GRB050724. Chandra observed this burst twice, about two days after the burst and a second time three weeks later. The first Chandra pointing occurred at the end of a strong late-time flare. About 150 photons were detected during this 49.3 ks observation in the 0.4-10.0 keV range. The spectral fit is ...
