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.

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.

Multiplicity in Star Formation
2012The previous chapter formulated the characteristics of the formation of single young stars not taking in account effects of fragmentation. That fragmention in critical stages when seed stars form is likely to occur throughout the Galaxy. This implies that the vast majority of protostars and PMS stars are found in multiple systems.

Multiple Stars: Physics vs. Dynamics
2007We review physical and dynamical parameters of multiple stars. Possible scenaria of multiple star formation are discussed: their birth in dense cloud cores and the decay of small stellar groups and clusters. We compare physical and dynamical features of simulated multiple stars formed by these processes with the actual multiple stars.

The observational study of double and multiple stars is traditionally seen as comprised of several specialized subfields, each defined by particular observational selection effects. Improvements in increased precision and accuracy, higher resolution, higher signal-to-noise ratios, greater sensitivity etc.), are leading the study of double stars to a ...

The nature of research on double and multiple stars has changed drastically during the past several decades. Prior to then the research was mostly concerned with visual measures for the purposes of obtaining orbital elements and masses. Then came spectroscopic studies that (1) when combined with the visual orbital elements allowed the determination of ...
