Infrared Spectroscopy of Interstellar Dust
, 2009 IR spectroscopy is the premier tool to study the composition of interstellar dust. Broad absorption and emission bands provide direct identification of the solid compounds present in space and allow measurement of accurate abundances. Systematic studies

Bibechana, 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.

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Water ice is an important rock‐forming mineral, both on the Earth and on various extraterrestrial bodies. Naturally occurring ice is often “dirty”–an intimate mixture with harder mineral grains, which can have significant effects on the bulk properties of the aggregate. We have used neutron powder diffraction, with in situ triaxial deformation,

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space
The Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

Stochastic histories of dust grains in the interstellar medium [PDF]
, 1989 The purpose is to study an evolving system of refractory dust grains within the Interstellar Medium (ISM). This is done via a combination of Monte Carlo processes and a system of partial differential equations, where refractory dust grains formed within ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
Global Policy, Volume 17, Issue 4, Page 553-565, September 2026.ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Interrelationships between interstellar and interplanetary grains [PDF]
, 1986 The relationship between solar system dust (SSD) and interstellar dust particles (ISMD) is being reconsidered because of the discovery of isotopic anomalies in meteorites.

Parameterizing the interstellar dust temperature [PDF]
, 2017 The temperature of interstellar dust particles is of great importance to astronomers. It plays a crucial role in the thermodynamics of interstellar clouds, because of the gas-dust collisional coupling.
