Fission Hypothesis of Binary Star Formation

 "This paper is concerned with one of the oldest hypotheses in stellar-evolution theory, namely, that a binary system originates from the splitting of a single star into two components due to rotational instability during contraction of the star. In spite of many attempts, no satisfactory theory of this process has been developed …" — Drawn from §I of Ian W. Roxburgh (1966)

Fission in Nuclear Physics

The nuclear physics community also draws an analogy between the fission of a rotating fluid drop and the spontaneous fission of atomic nuclei; see, for example, the figure associated with the Wikipedia discussion of the energetics of nuclear fission.

Drop Dynamics Experiments

[On 1 January 2014, J. E. Tohline wrote ...] As I was putting this chapter together, I had difficulty documenting the various drop dynamics experiments that have been conducted by astronauts in various Earth-orbiting (zero g) environments. Here is the relevant information that I have found, to date.

Skylab

Experiments showing the fission of liquid drops were evidently conducted during the Skylab 2, Skylab 3, and Skylab 4 missions (circa 1973-1974).

 According to the Teacher's Guide mentioned above, the activities shown in the above-referenced films were carried out by three teams of Skylab Astronauts: Kerwin blows water droplet from a straw Skylab 2 (First Team)

Space Shuttle Flights

Experiments illustrating the dynamical behavior of liquid drops were conducted during several space shuttle missions. Some experiments were performed inside the European Space Agency's "spacelab module" and others were performed with the aid of a "Drop Physics Module (DPM)" inside the United States Microgravity Laboratory (USML), each being a "portable" laboratory that was housed in the shuttle's payload bay.
