摘要：A detailed analysis of the BeX system 4U 0115+63 is presented. ISGRI data of the last two bright outbusrts of the source (September, 2004 and April 2008) have been used. The overall behaviour of 4U 01156+63 is that of a typical transient BeX system. However, ISGRI data show very interesting timing properties, and tell a beautiful story about the onset and evolution of a 2.1 mHz and a 1mHz QPOs, close in time to the maximum luminosity, in the 2004 and 2008 outbursts respectively. QPO changes and its possible origin are discussed.
