Accretion physics in the Galaxy - Long-term monitoring of black hole X-ray novae with MAXI/GSC and SSC
Abstract
MAXI is an all-sky X-ray monitor on the International Space Station, which started observation in August 2009. Since then, MAXI has been monitoring all-sky variable X-ray sources for three-years. MAXI had successfully detected state transitions in Cygnus X-1 and Swift J1753.5-0127, and monitored ~15 galactic BH novae including new sources as MAXI J1659-192, MAXI J1543-564, MAXI J1836-194, and MAXI J1910-057(=Swift J1910.2-0546). MAXI capability enabled to take high-cadence spectra of entire the state-transition and outburst. In this paper, we show the MAXI spectral analysis of 4U 1630-472 in the bright and variable period around MJD 56050-56080 and short-time soft statetransition at MJD 56035 with MAXI/GSC and SSC. We also report the results of follow-up observations of MAXI J1836-194 with Suzaku, Swift and RXTE.
