摘要：4U 2206+54 is one of the most intriguing X-Ray binaries. While showing properties closer to those of wind-fed supergiant X-Ray binaries, its optical counterpart lies in the main sequence, and recently it has been suggested that it may harbor an accretion disk (Finger et al. 2010). Only recently the real nature of the compact object has been revealed by the discovery of X-Ray pulsations (Reig et al. 2009). A detailed analysis of ISGRI data on this source is shown. The pulse period of 4U 2206+54 is analyzed and the properties of its pulse profile are discussed.
