New Candidate Massive Clusters from 2MASS [PDF]

, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

Diffuse interstellar bands in the spectra of Herbig Ae/Be stars and related objects [PDF]

, 2003
We report a detection of weak diffuse interstellar bands (DIBs) in the close vicinity of 6 Herbig Ae/Be pre-main sequence stars. A common feature of these objects is the presence of a dusty shell where DIB carriers are apparently formed/destroyed.

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

The Kinematic Age of 3I/ATLAS and Its Implications for Early Planet Formation

The Astrophysical Journal Letters
The recent discovery of the third interstellar object (3I/ATLAS) expands the known census from two to three and significantly improves statistical inferences regarding the underlying Galactic population.

Clathrate hydrate crystallization

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

Interstellar Travel and Traversable Wormholes [PDF]

, 2014
Sending Starships into deep space is a dream that human being has begun to consider when the first flight had success. Since then a lot of progress has been done but without breaking the ultimate barrier we have to pass: the speed of light.

Near-discovery Observations of Interstellar Comet 3I/ATLAS with the NASA Infrared Telescope Facility

The Astrophysical Journal Letters
Interstellar objects are comets and asteroids that formed around other stars but were ejected before they could accrete into exoplanets. They therefore represent a rare opportunity to compare the the building blocks of planets in the solar system to ...

Interstellar extinction from photometric surveys: application to four high-latitude areas

Open Astronomy, 2018
Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a

The interstellar object significance scale (Loeb Scale): astronomical classification of interstellar objects

International Journal of Astrobiology
Abstract The Vera C. Rubin Observatory is expected to increase interstellar object (ISO) detections from a few over the past decade to potentially one per few months, demanding a systematic classification scheme. We present the Interstellar Object Significance Scale (IOSS), also known in the literature as the Loeb Scale, a 0–10 ...

Interstellar Objects from Broken Dyson Spheres

Research Notes of the AAS, 2023
Abstract Without extensive maintenance, Dyson spheres inevitably disintegrate by asteroid impacts over billions of years. The resulting fragments would appear as anomalous interstellar objects, potentially sharing the unusual shape and motion of 1I/‘Oumuamua or the unusual material strength of the first two interstellar meteors, IM1 and ...
