Galactic X-rays observed with X-ray astronomy satellite ‘Hakucho’

Highlights of the results obtained with Japanese X-ray astronomy satellite Hakucho are reviewed. After a brief account of instrumentation (Section 2), some new features of non-bursting, non-pulsating objects are presented (Sections 3–5). The main part of the present review is devoted for X-ray bursts which are found more complex than one might have thought (Sections 6–11). The observation of X-ray pulsar, including a change of spin rate of Vela X-1, is described (Section 12). The main results obtained in the first two years are summarized in Section 13.
