After the first X-ray observation with SAS-3(MXB 1742-29), 1A 1742-294 has been observed with various X-ray satellites including Granat/ART-P (Lutovinov et al. 2001). On 12th March 2007, Suzaku observed 1A 1742-294 during the Galactic center survey with 27 ksec exposure. Both the XIS and HXD PIN detected five bursts. Thanks to high sensitivities of Suzaku instruments, Suzaku successfully detected 1/4th dimmer bursts than those by Granat at the flux of up to 10 mCrab level in the same bandpass. The persistent spectrum can be reproduced by a bremsstrahlung model with a temperature of \u003e 27 keV, which is over 3 times larger than 7.8 keV reported by Lutovinov et al. (2001). The average color temperature of bursts lies in 2-3 keV, which are canonical values of type I X-ray bursts. The time profiles of the bursts are well characterized by a fast rise (7 sec) followed by a smooth exponential decay.

内容記述 | The object 1A 1742-294 is a type I (thermonuclear) X-ray burster having the brightest persistent X-ray emission in the Galactic center region. After the first X-ray observation with SAS-3(MXB 1742-29), 1A 1742-294 has been observed with various X-ray satellites including Granat/ART-P (Lutovinov et al. 2001). On 12th March 2007, Suzaku observed 1A 1742-294 during the Galactic center survey with 27 ksec exposure. Both the XIS and HXD PIN detected five bursts. Thanks to high sensitivities of Suzaku instruments, Suzaku successfully detected 1/4th dimmer bursts than those by Granat at the flux of up to 10 mCrab level in the same bandpass. The persistent spectrum can be reproduced by a bremsstrahlung model with a temperature of > 27 keV, which is over 3 times larger than 7.8 keV reported by Lutovinov et al. (2001). The average color temperature of bursts lies in 2-3 keV, which are canonical values of type I X-ray bursts. The time profiles of the bursts are well characterized by a fast rise (7 sec) followed by a smooth exponential decay. The decay time depends on the X-ray energy; 29.7, 18.4 and 12.0 sec in the 0.2-4 keV, the 4-8 keV and the 8-12 keV band, respectively. | |||||
