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…
Voyager 1/UVS Lyman measurements at the distant heliosphere (90-130AU): unknown source of additional emission
O. A. Katushkina, E. Quemerais, V. V. Izmodenov +2
In this work, we present for the first time the Lyman intensities measured by Voyager 1/UVS in 2003-2014 (at 90-130 AU from the Sun). During this period Voyager 1 measured the…
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,…
Stability of the interstellar hydrogen inflow longitude from 20 years of SOHO/SWAN observations
Dimitra Koutroumpa, Eric Quémerais, Olga Katushkina +3
Aims. A recent debate on the decade-long stability of the interstellar He flow vector, and in particular the flow longitude, has prompted us to check for any variability in the int…
