On Estimating the Masses of Star Clusters Embedded in Clouds of Interstellar Gas and Dust
AbstractIn the article, a method is developed for estimating the dynamic masses of the stellar and gas components of cluster-cloud systems under...

Modeling of the Interstellar Medium Optical Absorption Spectrum by Primitive Hybrid Molecules C24H30, C32H36, and C73H74
AbstractAccounting for the different contributions of the aromatic rings, separated with sp 3 bonds, with ab initio method we constructed the hybrid...

Interaction of an acceleration wave with a characteristic shock in Interstellar gas clouds
In this paper, we have considered the van der Waals equation of state to study the one-dimensional spherically symmetric self-gravitating...

The Interstellar Medium
Except in particular situations, the behaviour of ordinary gases is adiabatic. In fact, due to the low values of the viscosity coefficients and... -
An Ab Initio Computational Study of Binding Energies of Interstellar Complex Organic Molecules on Crystalline Water Ice Surface Models
The interstellar medium is extremely heterogeneous in terms of physical environments and chemical composition. Spectroscopic observations in the... -
The Interaction of the Active Nucleus with the Host Galaxy Interstellar Medium
Imaging X-ray spectroscopy of nearby AGNs, mostly with Chandra, has shown that extended soft (<2.5 keV) emission-line-dominated X-ray biconical... -
System Engineering a Solar Thermal Propulsion Mission Concept for Rapid Interstellar Medium Access
The interstellar medium (ISM) represents the next frontier in space exploration, with many new discoveries to be made. The challenge, being so far...

Dust from the Interstellar Medium
The presence of dust in the interstellar medium was highlighted by Trumpler who, in an investigation of the diameters of Galactic clusters, found a... -
Small molecules, big impact: a tale of hydrides past, present, and future
Formed at an early stage of gas-phase ion-molecule chemistry, hydrides – molecules containing a heavy element covalently bonded to one or more...

Principal Studies of the First Solid Material Formed in the Early Solar System: A Review
Abstract —This publication reviews principal recent studies of the earliest solid material in the Solar System: refractory objects, which include...

A radio-detected type Ia supernova with helium-rich circumstellar material
Type Ia supernovae (SNe Ia) are thermonuclear explosions of degenerate white dwarf stars destabilized by mass accretion from a companion star

Direct measurement of decimetre-sized rocky material in the Oort cloud
The Oort cloud is thought to be a reservoir of icy planetesimals and the source of long-period comets (LPCs) implanted from the outer Solar System...

The Interaction of the Active Nucleus with the Host Galaxy Interstellar Medium
Imaging X-ray spectroscopy of nearby AGNs, mostly with Chandra, has shown that extended soft (<2.5 keV) emission-line-dominated X-ray biconical... -
Dust/ice mixing in cold regions and solid-state water in the diffuse interstellar medium
Whether ice in cold cosmic environments is physically separated from the silicate dust or mixed with individual silicate moieties is not known....

The S \(^+\) ( \(^4\) S)+SiH \(_{2}\) ( \(^1\) A \(_1\) ) Reaction: Toward the Synthesis of Interstellar SiS
We have performed a theoretical investigation of the S \(^+\)... -
On A Hypothetical Mechanism of Interstellar Life Transfer Trough Nomadic Objects
Lethal radiation, low vacuum pressure and low temperatures – this is how space welcomes organisms. Crossing of immense interstellar distances...

The Early History of Heliospheric Science and the Spacecraft That Made It Possible
Our understanding of the interaction of the large-scale heliosphere with the local interstellar medium (LISM) has undergone a profound change since...

The ramp-up of interstellar medium enrichment at z > 4
Fluorine is one of the most interesting elements for nuclear and stellar astrophysics
1 ,2 . Fluorine abundance was first measured for stars other than...
