Hachisu Self-Consistent-Field Technique
In 1986, Izumi Hachisu published two papers in The Astrophysical Journal Supplement Series (Vol. 61, p. 479, and Vol. 62, p. 461) describing "A Versatile Method for Obtaining Structures of Rapidly Rotating Stars." (Henceforth, we will refer to this method as the Hachisu Self-Consistent-Field, or HSCF, technique.) We have found the HSCF technique to be an extremely powerful tool for constructing equilibrium configurations of self-gravitating fluid systems under a wide variety of different circumstances. This chapter has been built upon an (ca. 1999) outline of the HSCF technique that appeared in our original version of this HyperText Book (H_Book). The photo of Professor Izumi Hachisu shown here, on the left, dates from the mid-1980s — about the time he developed this remarkably useful numerical technique; a more recent photo can be found on the web page associated with Professor Hachisu's current faculty appointment at the University of Tokyo, Komaba.
