, 2012 This is the process by which basic material such as gas and dust becomes a gravitating, self-luminous object. This is a complex process involving physics and chemistry, gravitation, rotation, magnetic fields and turbulence, and temperature, density and scale.

To interpret astronomical phenomena in the realm of double and multiple stars, is to disclose a series of startling discoveries and point the way to further revelation, all having a tremendous significance in general physics, mathematics and philosophy as well.

Binary and Multiple Star Formation
Astrophysics and Space Science, 1994From the growing observational evidence that binary/multiple star formation occurs prior to the pre-main sequence (Mathieu, 1992), it is clear that any theory of star formation MUST also explain binary formation. This paper details two formation mechanisms for binary/multiple stars, which occur simultaneously with protostar formation.

Double and Multiple Stars [PDF]
, 1985 Commission 26 has changed its name. The new denomination, warmly promoted by Dommanget, represents more adequately the actual field of the Commission itself and appears as a good start for extending its interest beyond the traditional aspects (morphology and statistics) and plunging into problems connected with the origin, evolution, mass spectrum and ...

In the recent years new techniques are expanding visual binary star astronomy into previously inaccessible regimes of angular resolution and accuracy of measurements regarding the astrometric and astrophysical parameters of their components. New techniques and algorithms are providing enhanced sensitivity to low mass companions and the determination of

When examining the statistics of multiple stars in the field, especially coming from visual binary star point of view, several problems present themselves. First, and most importantly, is distinguishing between physical multiples and optical pairs. Establishing physicality is not a simple ”binary” response as there are degrees of certainty.

The Formation of Multiple Stars
2007We have undertaken a series of SPH hydrodynamic + N-body simulations in order to explore the multiplicity properties of young stars. We find that binary and multiple stars are a natural outcome of collapsing turbulent flows, with a high incidence of N > 2 systems, specially among the higher mass objects.

In this thesis, I present a study of the formation and evolution of stars, particularly multiple stellar systems. Binary stars provide a key constraint on star formation because any successful model should reproduce the mass-dependent frequency, distribution of separations, and distribution of mass ratios.
