Free-Fall Collapse of an Homogeneous Spheroid

Free-Fall Collapse of an Homogeneous Spheroid

"In the course of researches on the formation of galaxies one meets the following idealized problem. What is the form of the collapse under gravitational forces of a uniformly rotating spheroidal gas cloud? In the special case where initially the gas is absolutely cold and of uniform density within the spheroid, we show that the collapse proceeds through a series of uniform, uniformly rotating spheroids until a disk is formed."

  NOTE … according to the new ADS listing, the authors associated with this paper should be, D. Lynden-Bell & C. T. C. Wall (Charles Terence Clegg "Terry" Wall); however, the archived article, itself, lists Lynden-Bell as the sole author while indicating that the paper was simply being communicated by Wall.

Comment by J. E. Tohline: In §II of this "1964" article, Lynden-Bell references his 1962 article with an incorrect year (Lynden-Bell 1963); within his list of REFERENCES, the year (1962) is correct, but the journal volume is incorrectly identified as 50 (it should be vol. 58).
