On Rejuvenation in Massive Binary Systems
We introduce a set of stellar models for massive stars whose evolution has been affected by mass transfer in a binary system, at a range of metallicities. As noted by other authors, the effect of such mass transfer is frequently more than just rejuvenation. We find that, whilst stars with convective cores which have accreted only H-rich matter rejuvenate as expected, those stars which have accr...
متن کاملFormation of protoplanets from massive planetesimals in binary systems
More than half of stars reside in binary or multiple star systems and many planets have been found in binary systems. From theoretical point of view, however, whether or not the planetary formation proceeds in a binary system is a very complex problem, because secular perturbation from the companion star can easily stir up the eccentricity of the planetesimals and cause high-velocity, destructi...
متن کاملTidal evolution of eccentric orbits in massive binary systems
We study the tidal evolution of a binary system consisting of a 1.4M⊙ compact object in elliptic orbit about a 10M⊙ uniformly rotating main sequence (MS) star for various values of the initial orbital parameters. We apply our previously published results of 2D non-adiabatic calculations of the non-radial gand r-mode oscillations of the uniformly rotating MS star, and include the effects of reso...
متن کاملOn the Spectral Efficiency of Noncooperative Uplink Massive MIMO Systems
Massive multiple-input multiple-output (MIMO) systems have been drawing considerable interest due to the growing throughput demands on wireless networks. In the uplink, massive MIMO systems are commonly studied assuming that each base station (BS) decodes the signals of its user terminals separately and linearly while treating all interference as noise. Although this approach provides improved ...
متن کاملBinary systems and stellar mergers in massive star formation
We present a model for the formation of high-mass close binary systems in the context of forming massive stars through gas accretion in the centres of stellar clusters. A low-mass wide binary evolves under mass accretion towards a high-mass close binary, attaining system masses of order 30-50 M⊙at separations of order 1 AU. The resulting high frequency of binary systems with two massive compone...
