متن کاملEvolution of the Binary Fraction in Dense Stellar Systems
Using our recently improved Monte Carlo evolution code, we study the evolution of the binary fraction in globular clusters. In agreement with previous N -body simulations, we find generally that the hard binary fraction in the core tends to increase with time over a range of initial cluster central densities for initial binary fractions . 90%. The dominant processes driving the evolution of the...
متن کاملA practical model of convective dynamics for stellar evolution calculations
Turbulent motions in the interior of a star play an important role in its evolution, since they transport chemical species, thermal energy and angular momentum. Our overall goal is to construct a practical turbulent closure model for convective transport that can be used in a multidimensional stellar evolution calculation including the effects of rotation, shear and magnetic fields. Here, we fo...
متن کاملStellar collisions during binary–binary and binary–single star interactions
Physical collisions between stars occur frequently in dense star clusters, either via close encounters between two single stars, or during strong dynamical interactions involving binary stars. Here we study stellar collisions that occur during binary–single and binary–binary interactions, by performing numerical scattering experiments. Our results include cross sections, branching ratios, and s...
متن کاملMultiplicity in Early Stellar Evolution
Many reviews have been written on pre-main-sequence binaries over the past 25 years, e.g., Reipurth (1988), Zinnecker (1989), Mathieu (1994), and Goodwin (2010), and particular mention should be made of IAU Symposium No. 200 (Zinnecker and Mathieu, 2001), which is still today a useful reference. Most recently, Duchêne and Kraus (2013) review the binarity for stars of all masses and ages. Stimul...
