A Unified Three-dimensional Magnetohydrodynamic Model of the Solar Corona, Solar Wind, and Global Heliosphere with Turbulence Transport

open access: yesThe Astrophysical Journal
We present results from a unified three-dimensional magnetohydrodynamic model of the solar corona, solar wind, and global heliosphere that incorporates turbulence transport.

Physical properties of dust particles around white dwarf in far infrared sky at 12.8o galactic latitude

open access: yesBibechana, 2017
We study the  active region in the interstellar medium in which the process of cavity formation is expected. The interaction between wind and its surroundings in the interstellar medium (ISM) provides a laboratory to study the behavior of dust particles.

Determining the Interstellar Wind Longitudinal Inflow Evolution Using Pickup Ions in the Helium Focusing Cone

open access: yesThe Astrophysical Journal
The size, shape, and composition of the heliosphere are affected by its interaction with the local interstellar medium. A means of quantifying this interaction is by measuring the relative motion of the two media.

APPLICATION OF NUMERICAL METHODS TO MODELING THE STELLAR WIND AND INTERSTELLAR MEDIUM INTERACTION

open access: yes, 1998
We present a review of the application of numerical methods to solve the problem of the stellar/solar wind with the local interstellar medium. Most of approaches described are developed by the authors. They include both purely gas dynamic and magnetohydrodynamic methods.

Shocks, Compressible Perturbations, and Intermittency in the Very Local Interstellar Medium: Voyager 1 and 2 Observations and Numerical Modeling

open access: yesThe Astrophysical Journal
The Voyager spacecraft (V1 and V2) provide unique in situ measurements of perturbations propagating beyond the heliopause through the very local interstellar medium (VLISM), including the shocks and pressure fronts whose origin is debated. In particular,

Numerical study on the interaction of AGN winds and interstellar medium

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT Accretion disc winds can leave active galactic nuclei (AGNs) and interact with the interstellar medium (ISM) of their host galaxies. We perform two-dimensional numerical simulations to investigate the interaction of AGN winds and ISM.

An Anisotropic Plasma Model of the Heliospheric Interface

open access: yesThe Astrophysical Journal
We present a pioneering model of the interaction between the solar wind and the surrounding interstellar medium that includes the possibility of different pressures in directions parallel and perpendicular to the magnetic field.

W50 - a stellar-wind bubble in a three-phase interstellar medium? [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1983
L'interaction entre les jets relativistes de SS 433 et la nebuleuse radio W 50 est analysee sur la base d'observations recentes. On trouve que SS 433 pourrait etre entouree d'un milieu interstellaire nuageux, du type de celui decrit par le modele a 3 phases de McKee et Ostriker. W 50 est probablement une bulle interstellaire en expansion, entrainee par

Distance to the IBEX Ribbon beyond the Heliopause

open access: yesThe Astrophysical Journal
Our understanding of the solar–interstellar interaction greatly improved with measurements of energetic neutral atoms (ENAs) from the outer heliosphere by NASA’s Interstellar Boundary Explorer (IBEX).

WawHelioIonMP: A Semiempirical Tool for the Determination of Latitudinal Variation in the Ionization Rate of Interstellar Hydrogen and the Solar Wind

open access: yesThe Astrophysical Journal
The latitudinal structure of the solar wind varies during the cycle of solar activity. Analysis of this variation is important for understanding the solar activity and interpretation of observations of heliospheric energetic neutral hydrogen atoms and ...
