Exclusion of Tiny Interstellar Dust Grains from the Heliosphere [PDF]

, 2009
The distribution of interstellar dust grains (ISDG) observed in the Solar System depends on the nature of the interstellar medium-solar wind interaction.

Using numerical models of bow shocks to investigate the circumstellar medium of massive stars

, 2014
Many massive stars travel through the interstellar medium at supersonic speeds. As a result they form bow shocks at the interface between the stellar wind.

Interaction between massive star winds and the interstellar medium

Proceedings of the International Astronomical Union, 2021
AbstractMassive stars drive strong winds that impact the surrounding interstellar medium, producing parsec-scale bubbles for isolated stars and superbubbles around young clusters. These bubbles can be observed across the electromagnetic spectrum, both the wind itself and the swept up interstellar gas.

The density distribution and 58.4 nm radiation intensity of interstellar helium in the heliosphere: a model simulation

Earth and Planetary Physics
Research on the interstellar medium and its interaction with the solar system constitutes a significant topic in planetary physics. As the Sun traverses the local interstellar cloud, interstellar neutrals penetrate the heliosphere, forming the ...

The effects of stellar winds of fast-rotating massive stars in the earliest phases of the chemical enrichment of the Galaxy

, 2010
We use the growing data sets of very-metal-poor stars to study the impact of stellar winds of fast rotating massive stars on the chemical enrichment of the early Galaxy.

The Cassiopeia Filament: A Blown Spur of the Local Arm

The Astronomical Journal, 2022
We present wide-field and high-sensitivity CO(1–0) molecular line observations toward the Cassiopeia region, using the 13.7 m millimeter telescope of the Purple Mountain Observatory.

Accelerated Discovery‐to‐Unveiling of High‐Performance and Affordable Ammonia Electrode Process by Human–Machine Collaboration Framework

Angewandte Chemie International Edition, EarlyView.
By employing dimensionally reduced reaction descriptors, a human–machine collaboration framework for efficient electrochemical nitrate reduction to NH3 electrocatalysts screening is established and drastically shorten the discovery timeframe. A new kinetic model is established in combination with a rotating ring‐disk electrode, unveiling the pivotal ...

Wind bubbles within H II regions around slowly moving stars [PDF]

, 2014
Interstellar bubbles around O stars are driven by a combination of the star's wind and ionizing radiation output. The wind contribution is uncertain because the boundary between the wind and interstellar medium is difficult to observe.

A Predicted Small and Round Heliosphere [PDF]

, 2018
The shape of the solar wind bubble within the interstellar medium, the so-called heliosphere, has been explored over six decades. As the Sun moves through the surrounding partially-ionized medium, neutral hydrogen atoms penetrate the heliosphere, and ...

Density Spectrum in the Diffuse Interstellar Medium and Solar Wind

The Astrophysical Journal, 2004
Inertial range turbulence properties are investigated for nearly incompressible density fluctuations using two-dimensional nonlinear fluid simulations. We find that density fluctuations behave as a passive scalar and do not satisfy the pseudosound approximation.
