X-ray Halos and Large Grains in the Diffuse Interstellar Medium [PDF]

, 2001
Recent observations with dust detectors on board the interplanetary spacecraft Ulysses and Galileo have recorded a substantial flux of large interstellar grains with radii between 0.25 and 2.0 mu entering the solar system from the local interstellar ...

Recent progress in theory and observational study of dust grain alignment and rotational disruption in star-forming regions

Frontiers in Astronomy and Space Sciences, 2022
Modern understanding of dust astrophysics reveals that radiative torques (RATs) arising from the radiation–dust interaction can induce two fundamental effects: grain alignment and rotational disruption.

Orbital evolution under the action of fast interstellar gas flow with non-constant drag coefficient

, 2012
The acceleration of a spherical dust particle caused by an interstellar gas flow depends on the drag coefficient which is, for the given particle and flow of interstellar gas, a specific function of the relative speed of the dust particle with respect to

Aliphatic hydrocarbon content of interstellar dust [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
In the interstellar medium, carbon is distributed between the gas and solid phases. However, while about half of the expected carbon abundance can be accounted for in the gas phase, there is considerable uncertainty as to the amount incorporated in interstellar dust.

SpeX Near-infrared Spectroscopic Extinction Curves in the Milky Way

The Astrophysical Journal, 2022
Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observations for the effects of interstellar dust.

Dust evolution in pre-stellar cores [PDF]

EPJ Web of Conferences, 2020
Dust grains are the building blocks of future planets. They evolve in size, shape and composition during the life cycle of the interstellar medium. We seek to understand the process which leads from diffuse medium grains to dust grains in the vicinity of

Properties of interstellar wind leading to shape morphology of the dust surrounding HD 61005

, 2017
A structure formed by dust particles ejected from the debris ring around HD 61005 is observed in the scattered light. The main aim here is to constrain interstellar wind parameters that lead to shape morphology in the vicinity of HD 61005 using currently

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...
