چکیده
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. The source light curve shows the characteristic outburst shape observed in this source.

Discovery of a Transition to Global Spin-up in Exo 2030+375
EXO 2030+375, a 42-second transient X-ray pulsar with a Be star companion, has been observed to undergo an outburst at nearly every periastron passage for the last 13.5 years. From 1994 through 2002, the global trend in the pulsar spin frequency was spin-down. Using RXTE data from 2003 September, we have observed a transition to global spin-up in EXO 2030+375. Although the spin frequency observ...
متن کاملA Decade in the Life of EXO 2030+375: A Multi-wavelength Study of an Accreting X-ray Pulsar
Using BATSE and RXTE observations from 1991 April to 2001 August we have detected 71 outbursts from 82 periastron passages of EXO 2030+375, a 42-second transient X-ray pulsar with a Be star companion, including several outbursts from 1993 August to 1996 April when the source was previously believed to be quiescent. Combining BATSE, RXTE, and EXOSAT data we have derived an improved orbital solut...

We report the discovery of a high-energy transient with the IBIS/ISGRI detector on board the INTEGRAL observatory. The source, namely IGR J00291+5934, was first detected on 2nd December 2004 in the routine monitoring of the IBIS/ISGRI 20–60 keV images. The observations were conducted during Galactic Plane Scans, which are a key part of the INTEGRAL Core Programme observations. After verifying t...
متن کاملThe 3rd Ibis/isgri Soft Gamma-ray Survey Catalog *
In this paper we report on the third soft gamma-ray source catalog obtained with the IBIS/ISGRI gamma-ray imager on board the INTEGRAL satellite. The scientific dataset is based on more than 40 Ms of high quality observations performed during the first three and a half years of Core Program and public IBIS/ISGRI observations. Compared to previous IBIS/ISGRI surveys, this catalog includes a subs...
متن کاملINTEGRAL 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 ...
