CPD-64 2731: a massive spun-up and rejuvenated high-velocity runaway star
V. V. Gvaramadze, O. V. Maryeva, A. Y. Kniazev +4
We report the results of our study of the high-velocity (\approx160 km/s) runaway O star CPD-64 2731 and its associated horseshoe-shaped nebula discovered with the Wide-field Infra…
Modelling interstellar structures around Vela X-1
V. V. Gvaramadze, D. B. Alexashov, O. A. Katushkina +1
We report the discovery of filamentary structures stretched behind the bow-shock-producing high-mass X-ray binary Vela X-1 using the SuperCOSMOS H-alpha Survey and present the resu…
Non-monotonic spatial distribution of the interstellar dust in astrospheres: finite gyroradius effect
Olga Katushkina, Dmitry Alexashov, Vladislav Izmodenov +1
High-resolution mid-infrared observations of astrospheres show that many of them have filamentary (cirrus-like) structure. Using numerical models of dust dynamics in astrospheres,…
Two-jet astrosphere model: effect of azimuthal magnetic field
E. A. Golikov, V. V. Izmodenov, D. B. Alexashov +1
Opher et al. (2015), Drake et al. (2015) have shown that the heliospheric magnetic field results in formation of two-jet structure of the solar wind flow in the inner heliosheath,…
Interstellar hydrogen fluxes measured by IBEX-Lo in 2009: numerical modeling and comparison with the data
O. A. Katushkina, V. V. Izmodenov, D. B. Alexashov +2
In this paper, we perform numerical modeling of the interstellar hydrogen fluxes measured by IBEX-Lo during orbit 23 (spring 2009) using a state-of-the-art kinetic model of the int…
Electron thermal conduction as a possible mechanism to make the inner heliosheath thnner
V. V. Izmodenov, D. B. Alexashov, M. S. Ruderman
We show that the electron thermal conductivity may strongly affect the heliosheath plasma flow and the global pattern of the solar wind (SW) interaction with the local interstellar…
Scatter-free pickup ions beyond the heliopause as a model for the Interstellar Boundary Explorer (IBEX) ribbon
S. V. Chalov, D. B. Alexashov, D. McComas +3
We present new kinetic-gasdynamic model of the solar wind interaction with the local interstellar medium. The model incorporates several processes suggested by McComas et al. (2009…
