Population synthesis of wide binary millisecond pulsars
Four evolutionary channels leading to the formation of wide binary millisecond pulsars are investigated. The majority of binary millisecond pulsars are found to descend from systems in which the most massive component undergoes a common-envelope phase prior to the supernova explosion leading to the birth of the neutron star. The orbital period distribution of simulated samples of wide binary mi...
متن کاملBinary Population Synthesis: Methods, Normalization, and Surprises
In this paper we present a brief overview of population synthesis methods with a discussion of their main advantages and disadvantages. In the second part, we present some recent results from synthesis models of close binary compact objects with emphasis on the predicted rates, their uncertainties, and the model input parameters the rates are most sensitive to. We also report on a new evolution...
متن کاملHow binary interactions affect stellar population synthesis
The single star-stellar population (ss-SSP) models are usually used for stellar population studies. However, there are more than 50% stars that are in binaries and evolve differently from single stars. This suggests when we model the stellar populations of galaxies and star clusters, the effects of binary interactions should be considered. Although a few works tried to model stellar populations...
متن کاملConstraining Population Synthesis Models via the Binary Neutron Star Population
The observed sample of double neutron-star (NS-NS) binaries presents a challenge to populationsynthesis models of compact object formation: the parameters entering into these models must be carefully chosen so as to match (i) the observed star formation rate and (ii) the formation rate of NS-NS binaries, which can be estimated from the observed sample and the selection effects related to the di...
متن کاملBinary Population Synthesis: Low- and Intermediate-mass X-ray Binaries
As has only recently been recognized, X-ray binaries with intermediatemass secondaries are much more important than previously believed. To assess the relative importance of lowand intermediate-mass X-ray binaries (LMXBs and IMXBs), we have initiated a systematic study of these systems consisting of two parts: an exploration of the evolution of LMXBs and IMXBs for a wide range of initial masses...
