Time-Frequency Analysis Superorbital Modulation X-ray Binary SMC X-1 Hilbert-Huang Transform
2011/10/21
The high-mass X-ray binary (HMXB) SMC X-1 exhibits a superorbital modulation with a dramatically varying period ranging between ~40 d and ~60 d. This research studies the time-frequency properties of ...
RXTE Observations of the Low-Mass X-Ray Binary 4U 1608-522 in Upper-Banana State
RXTE Observations Low-Mass X-Ray Binary 4U 1608-522 Upper-Banana State
2011/10/11
To investigate the physics of mass accretion onto weakly-magnetized neutron stars, 95 archival RXTE datasets of an atoll source 4U 1608-522, acquired over 1996-2004 in so-called upper-banana state, we...

Be/X-ray binary A0535+26 during recent 2009/2010 outbursts
2011/10/10
The Be/X-ray binary A0535+26 showed a giant outburst in December 2009 that reached ~5.14 Crab in the 15-50 keV range. Unfortunately, due to Sun constraints it could not be observed by most X-ray satel...

The effect of coronal radiation on a residual inner disk in the low/hard spectral state of black hole X-ray binary systems
accretion accretion disks — black hole physics —X-rays bi-naries — X-rays stars
2010/11/15
Thermal conduction between a cool accretion disk and a hot inner corona can result in either evaporation of the disk or condensation of the hot corona. At low mass accretion rates, evaporation dominat...
