Binary-binary Interactions and the Formation of the Psr B162026 Triple System in M4
نویسندگان
چکیده
The hierarchical triple system containing the millisecond pulsar PSR B162026 in M4 is the rst triple star system ever detected in a globular cluster. Such systems should form in globular clusters as a result of dynamical interactions between binaries. We propose that the triple system containing PSR B162026 formed through an exchange interaction between a wide primordial binary and a pre-existing binary millisecond pulsar. This scenario would have the advantage of reconciling the 10 9 yr timing age of the pulsar with the much shorter lifetime of the triple system in the core of M4.

The Triple Pulsar System Psr B1620−26 in M4
The millisecond pulsar PSR B1620−26, in the globular cluster M4, has a white dwarf companion in a half-year orbit. Anomalously large variations in the pulsar’s apparent spin-down rate have suggested the presence of a second companion in a much wider orbit. Using timing observations made on more than seven hundred days spanning eleven years, we confirm this anomalous timing behavior. We explicit...

Previous timing data for PSR B1620−26 were consistent with a second companion mass m 2 anywhere in the range ∼ 10 −3 − 1 M ⊙ , i.e., from a Jupiter-type planet to a star. We present the latest timing parameters for the system, including a significant change in the projected semi-major axis of the inner binary, a marginal detection of the fourth time derivative of the pulse frequency, and the pu...

This study investigates the separation based on adsorption of the binary gas mixture of hydrogen withbiogas (gases: CO2, CH4, O2, N2) and inert gases (gases: He, Ne, and Ar) using single-walled ((7,7), (15,15),(29,29), (44,44), (58,58) and (73,73) SWBNNTs), double-walled ((11,11)@(15,15), (7,7)@(22,22) DWBNNTs)and triple walled ((8,8)@(11,11)@(15,15) and (7,7)@(15,15)@(22,22) ...
متن کاملMeasurement of Selected Thermophysical and Viscosity of Binary Mixtures of Nitromethane with 2-Propanol, 2-Butanol and 2-Pentanol
The density and viscosity values at T= (293.15 to 323.15) K for binary mixtures of nitromethane with 2-propanol, 2-butanol and 2-pentanol were measured over the entire composition range. From the experimental data, excess molar volumes, thermal expansion coefficients, excess thermal expansions, partial molar volumes at infinite dilution and deviations in viscosity were calculated. The results w...
متن کاملEulerian Lagrangian Simulation of Particle Capture and Dendrite Formation on Binary Fibers
The capture efficiency of the small aerosol particle is strongly influenced by the structure of fibrous layers. This study presents particle deposition and dendrite formation on different arrangements of binary fibers. 2-D numerical simulation is performed using the open source software of OpenFOAM. In the instantaneous filtration of a single fiber, obtained results are in good agreement with th...
