Evolution of Low-mass Helium Stars in Semidetached Binaries
We present results of a systematic investigation of the evolution of low-mass (0.35 M⊙, 0.40 M⊙ and 0.65 M⊙) helium donors in semidetached binaries with accretors – white dwarfs. In the initial models of evolutionary sequences abundance of helium in the center 0.1 < ∼ Yc ≤ 0.98. Results of computations may be applied to the study of the origin and evolutionary state of AM CVn stars. It is shown...
متن کامل3D numerical simulation of gaseous flows structure in semidetached binaries
The results of numerical simulation of mass transfer in semidetached non-magnetic binaries are presented. We investigate the morphology of gaseous flows on the base of three-dimensional hydrodynamic calculations in interacting binaries of different types (cataclysmic variables and low-mass X-ray binaries). We find that taking into account of a circumbinary envelope leads to significant changes ...
متن کاملThree-dimensional Modeling of the Matter Flow Structure in Semidetached Binary Systems
Results of numerical simulations of matter flows in a semidetached binary system similar to the low-mass X-ray binary X1822–371 are presented. Three-dimensional modeling of the mass transfer gas dynamics makes it possible to investigate gas streams in the system and to study the influence of a common envelope. The presence of the common envelope leads to the absence of shock interaction between...
متن کاملThe Influence of Parameters on the Flow Structure in Semidetached Binary Systems: 3D Numerical Simulation
The basic parameters determining the flow pattern for a nonviscous, non-heatconducting gas in a semidetached binary system without a magnetic field are identified. Three-dimensional gas–dynamical modeling of the mass transfer enables investigation of the influence of these parameters on the structure of gas flows. The parameter on which the flow pattern depends most strongly is the adiabatic in...
متن کاملScheduling a constellation of agile earth observation satellites with preemption
In this paper, we consider a scheduling problem for a set of agile Earth observation satellites for scanning different parts of the Earth’s surface. We assume that preemption is allowed to prevent repetitive images and develop four different preemption policies. Scheduling is done for the imaging time window and transmission time domain to the Earth stations as well. The value of each picture ...
