INTEGRAL observations of the Be/X-ray binary EXO 2030+375 during outburst
We present a type–I outburst of the high-mass X–ray binary EXO 2030+375, detected during INTEGRAL’s Performance and Verification phase in December 2002 (on–source time about 10 seconds). In addition, six more outbursts have been observed during INTEGRAL’s Galactic Plane Scans. X-ray pulsations have been detected with a pulse period of 41.691798±0.000016 s. The X-ray luminosity in the 5–300 keV ...
متن کاملA Strong X-ray Burst from the Low-mass X-ray Binary Exo 0748 676
We have observed an unusually strong X-ray burst as a part of our regular eclipse timing observations of the lowmass binary system EXO 0748 676. The burst peak flux was 5:2 ; 10 8 ergs cm s , approximately 5 times the normal peak X-ray burst flux observed from this source by RXTE. Spectral fits to the data strongly suggest that photospheric radius expansion occurred during the burst. In this pa...
متن کاملSimultaneous radio and X-ray observations of the low-mass X-ray binary GX 13+1
We present the results of two simultaneous X-ray/radio observations of the low-mass X-ray binary GX 13+1, performed in July/ August 1999 with the Rossi X-ray Timing Explorer and the Very Large Array. In X-rays the source was observed in two distinct spectral states; a soft state, which had a corresponding 6 cm flux density of ∼0.25 mJy, and a hard state, which was much brighter at 1.3–7.2 mJy. ...
متن کاملFirst observations of the X-ray transient EXO 2030+375 with IBIS/ISGRI
We present a first INTEGRAL observation of the 42 s transient X-ray pulsar EXO 2030+375 with IBIS/ISGRI. The source was detected during Cyg X-1 observations in December 2002. We analyzed observations during the outburst period from 9 to 21 December 2002 with a total exposure time of ∼770 kilosec. EXO 2030+375 was almost always detected during single ∼30 min exposures in the 18−45 energy bands. ...
