Interstellar Knowledge Dynamics
, 2023 Knowledge has always been an important cornerstone of our civilization, and we believe this will continue to be true for our future interstellar society. In this study, we construct an interstellar knowledge dynamics model, which allows us to explore how innovations would look like in a social system subjected to special relativity.

Dynamics of interstellar dust particles in electromagnetic radiation fields [PDF]
2016 URSI International Symposium on Electromagnetic Theory (EMTS), 2016 We establish a theoretical framework for solving the equations of motion for an arbitrarily shaped, isotropic, and homogeneous dust particle in the presence of radiation pressure. The scattering problem involved is solved by a surface integral equation method, and a rudimentary sketch of the numerical implementation is introduced with preliminary ...

Interstellar Gas Dynamics [PDF]
Publications of the Astronomical Society of Australia, 1968 It is a well established observational result that young stars exhibit differences in chemical composition. The differences are comparatively large. For example, some stars have metal abundances as high as 3/2 solar-value while others have abundances as low as 1/2 solar-value.

The Small-scale Dynamo in a Multiphase Supernova-driven Medium
The Astrophysical Journal, 2023 Magnetic fields grow quickly, even at early cosmological times, suggesting the action of a small-scale dynamo (SSD) in the interstellar medium (ISM) of galaxies. Many studies have focused on idealized, isotropic, homogeneous, turbulent driving of the SSD.

Multi-line Observations, Models, and Data Needed to Understand the Nature of UV-irradiated Interstellar Matter [PDF]
EPJ Web of Conferences, 2022 Far-ultraviolet photons from OB-type massive stars regulate the heating, ionization, and chemistry of much of the neutral interstellar gas in star-forming galaxies.

Frontiers in Astronomy and Space Sciences, 2023 The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...

DYNAMIC SPECTRAL MAPPING OF INTERSTELLAR PLASMA LENSES [PDF]
The Astrophysical Journal, 2016 ABSTRACT Compact radio sources sometimes exhibit intervals of large, rapid changes in their flux density, due to lensing by interstellar plasma crossing the line of sight. A novel survey program has made it possible to discover these “Extreme Scattering Events” (ESEs) in real time, resulting in a high-quality dynamic spectrum of an ESE ...
