Infrared dust arcs around the stars: I. effect of the radiation pressure
Olga Katushkina, Vladislav Izmodenov
In this paper we consider the distribution of the interstellar dust in the vicinity of the star under an influence of the stellar gravitation and radiation pressure. This study is…
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…
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…
Neutral interstellar helium parameters based on Ulysses/GAS and IBEX-Lo observations: what are the reasons for the differences?
Olga A. Katushkina, Vladislav V. Izmodenov, Brian E. Wood +1
Recent analysis of the interstellar helium fluxes measured in 2009-2010 at Earth orbit by the Interstellar Boundary Explorer (IBEX) has suggested that the interstellar velocity (bo…
Spectral properties of backscattered solar Ly-alpha radiation in the heliosphere: a theoretical search of the heliospheric boundaries effects
Olga A. Katushkina, Vladislav V. Izmodenov
We explore imprints of the solar wind interaction with the local interstellar medium on spectral properties of the backscattered solar Ly-alpha radiation. We employ newly developed…
Effect of the heliospheric interface on the distribution of interstellar hydrogen atom inside the heliosphere
Olga Katushkina, Vladislav Izmodenov
This paper deals with the modeling of the interstellar hydrogen atoms (H atoms) distribution in the heliosphere. We study influence of the heliospheric interface, that is the regio…
