I stand corrected; the majority of observed stars to date are single stars per Wikipedia. There exists a reference, "Binary Star Formation from Rotational Fragmentation". Can anybody summarize in a few sentences how this fragmentation occurs especially for close binaries?

Almost all the individual stars for each binary star system formed at the same time (which I recently learned). The majority of stars are binaries; single stars and other multiple systems represent the remainder of star systems. How does the nebula hypothesis or any other hypothesis address the formation of binaries being produced from the collapse of interstellar molecular clouds? Most observed binaries' orbital distances are inside the range of Neptune's orbit and the vast observed majority are inside the range of Mercury's orbit with many having some contact with each other.
