Fe Kα line in hard X-ray emitting symbiotic stars
The 6.4 keV iron emission line is typically created by irradiation of the neutral (or low ionized) iron by a hard X-ray source. Whereas the 6.7 and 7.0 keV emission lines are mainly produced by photoionization and collisional excitation in hot plasma, the 6.4 keV fluorescence line is typically a signature of either reflection from an accretion disc or absorption. We have surveyed the emission u...
متن کاملSwift OBSERVATIONS OF HARD X-RAY EMITTING WHITE DWARFS IN SYMBIOTIC STARS
The X-ray emission from most accreting white dwarfs (WDs) in symbiotic binary stars is quite soft. Several symbiotic WDs, however, produce strong X-ray emission at energies greater than ∼ 20 keV. The Swift BAT instrument has detected hard X-ray emission from 4 such accreting WDs in symbiotic stars: RT Cru, T CrB, CD −57 3057, and CH Cyg. In one case (RT Cru), Swift detected X-rays out to greate...
متن کاملX-ray emitting young stars in the Orion Nebula
The Orion Nebula Cluster and the molecular cloud in its vicinity have been observed with the ACIS-I detector on board the Chandra X-ray Observatory with 23 hours exposure in two observations. We detect 1075 X-ray sources, most with sub-arcsecond positional accuracy. Ninety-one percent of the sources are spatially associated with known stellar members of the cluster, and an additional 7% are new...
متن کاملRotational modulation of X-ray flares on late-type stars: T Tauri stars and Algol
We present evidence for rotational modulation of Xray flares by an analysis of four outbursts on late-type stars. Two of the flares we discuss are found in ROSAT observations of T Tauri Stars and were obtained between September and October 1991. A flare on the T Tauri Star V773 Tau was observed by ASCA in September 1995. To this sample we add a Ginga observation of a flare on Algol observed in ...
متن کاملX-ray Spectroscopy of Thermally Emitting Neutron Stars
I describe recent high-resolution X-ray spectroscopy of surface emission from nearby, thermally emitting neutron stars. I focus on RX J0720.4−3125, RX J1308.6+2127, and RX J1605.3+3249, all of which have similar temperature, but differ in the presence and strength of absorption features in their spectra. I discuss possible causes for the absorption we see in two sources, and conclude that it ma...
