Formación de sistemas binarios ultracompactos

Abstract

Estudiamos desde un punto de vista teórico los sistemas binarios ultracompactos (UCXBs) en el marco de los sistemas binarios interactuantes. Empleando nuestro código de evolución binaria investigamos la formación de los UCXBs explorando el espacio de parámetros del problema (período orbital y masa inicial de laestrella donante) con el objeto de hallar la región que da lugar a su formación. Tuvimos en cuenta el efecto de evaporación originada por el viento del púlsar y la irradiación mutua, efectos importantes a tener en cuenta en sistemas donde ambas componentes se encuentran muy próximas y que han sido ignorados en otros trabajos.

/ We study from a theoretical point of view the ultracompact binary systems (UCXBs) in the framework of interacting binary systems. Using our binary evolution code we investigate the formation of UCXBs by exploring the parameter space of the problem (orbital period and initial mass of the donor star) in order to find the region that gives rise to its formation. We took into account the evaporation effect caused by the pulsar wind and mutual irradiation. These are important effects to be taken into account in systems where both components are very close and that have been ignored in other papers.
