A Hard-to-Soft State Transition of Aquila X-1 Observed with Suzaku
Ko Ono, Kazuo Makishima, Soki Sakurai +3
The recurrent soft X-ray transient Aquila X-1 was observed with Suzaku for a gross duration of 79.9 ks, on 2011 October 21 when the object was in a rising phase of an outburst. Dur…
Suzaku Observation of the High-Inclination Binary EXO 0748-676 in the Hard State
Zhongli Zhang, Soki Sakurai, Kazuo Makishima +4
Utilizing an archived Suzaku data acquired on 2007 December 25 for 46 ks, X-ray spectroscopic properties of the dipping and eclipsing low-mass X-ray binary EXO 0748676 were stud…
A Suzaku Observation of the Low-Mass X-Ray Binary GS 1826-238 in the Hard State
K. Ono, S. Sakurai, Z. Zhang +2
The neutron star Low-Mass X-ray Binary GS 1826-238 was observed with Suzaku on 2009 October 21, for a total exposure of 103 ksec. Except for the type I bursts, the source intensity…
Probing the Accretion Scheme of the Dipping X-ray Binary 4U 1915-05 with Suzaku
Zhongli Zhang, Kazuo Makishima, Soki Sakurai +2
The dipping low-mass X-ray binary 4U 1915-05 was observed by Suzaku on 2007 November 8 for a net exposure of 39 ksec. It was detected by the XIS with a 0.8-10 keV signal rate of 9.…
Suzaku Studies of Luminosity-Dependent Changes in the Low-Mass X-ray Binary Aquila X-1
Soki Sakurai, Shunsuke Torii, Hirofumi Noda +7
The neutron-star Low-Mass X-ray Binary Aquila X-1 was observed by Suzaku for seven times, from 2007 September 28 to October 30. The observations successfully traced an outburst dec…
