| contents | THE FORMATION MASS OF A BINARY SYSTEM VIA FRAGMENTATION OF A ROTATING PARENT CORE WITH INCREASING TOTAL MASS Guillermo Arreaga-Garcíıa Física, Astronomía y Matemáticas stars methods numerical formation Hydrodynamics We present a set of numerical simulations of the gravitational collapse of a uniform and rotating core, in which azimuthal symmetric mass seeds are initially implemented in order to favor the formation of a dense filament, out of which a binary system may be formed by direct fragmentation. We observe that this binary formation process is diminished when the total mass of the parent core M0 is increased; then we increase the level of the ratio of rotational energy to the gravitational energy, denoted by β, initially supplied to the rotating core, in order to achieve the desired direct fragmentation of the filament. We measure the binary mass Mf obtained from an initial M0 and then show a schematic diagram M0 vs β, where the desired binary configurations are located. We also report some basic physical data of the fragments. 2016 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57146052012 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.52 |
