Abstract
Black hole X-ray binary (BHXB) GX 339-4 produces the most frequent X-ray outbursts (every 2-4 years) among known X-ray binary sources in our galaxy. Here we present the study of the evolution of GX 339-4 over the years of observations using the Hardness Intensity Diagram (HID), i.e., the q diagram. We present an analysis of two outbursts of the source observed by the Monitor of All-sky X-ray Image (MAXI) telescope aboard the International Space Station (ISS).
