Fast Radio Bursts and Interstellar Objects
The Astrophysical JournalFast radio bursts (FRBs) are transient radio events with millisecond-scale durations and debated origins. Collisions between planetesimals and neutron stars (NSs) have been proposed as a mechanism to produce FRBs; the planetesimal strength, size, and ...

Interstellar Now! Missions to Explore Nearby Interstellar Objects [PDF]
Advances in Space Research, 2021 International audienceThe recently discovered first hyperbolic objects passing through the Solar System, 1I/'Oumuamua and 2I/Borisov, have raised the question about near term missions to Interstellar Objects.

The Planetary Science Journal, 2023 The discovery of two interstellar objects passing through the solar system, 1I/‘Oumuamua and 2I/Borisov, implies that a galactic population exists with a spatial number density of order ∼0.1 au ^−3 .

Prospects for Backtracing 1I/‘Oumuamua and Future Interstellar Objects [PDF]
Astrophysical Journal Letters, 2018 1I/'Oumuamua is the first of likely many small bodies of extrasolar origin to be found in the solar system. These interstellar objects (ISOs) are hypothesized to have formed in extrasolar planetary systems prior to being ejected into interstellar space ...

The Astrophysical Journal, 2023 We investigate the thermal condensation caused by a massive object that passes through the interstellar medium with high velocity, and propose a mechanism for creating a filamentary gaseous object, or interstellar contrail.

Interstellar Extinction from Large Surveys
Open Astronomy, 2003 Under some assumptions, information on interstellar extinction may be obtained from modern large photometric survey data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys.

Interstellar dust within the life cycle of the interstellar medium
EPJ Web of Conferences, 2012 Cosmic dust is omnipresent in the Universe. Its presence influences the evolution of the astronomical objects which in turn modify its physical and chemical properties.

He Awa Whiria: The Tidal Streams of Interstellar Objects
The Astrophysical JournalUpcoming surveys are likely to discover a new sample of interstellar objects (ISOs) within the solar system, but questions remain about the origin and distribution of this population within the Galaxy.

Strength Ratios of Diffuse Interstellar Bands in Slightly Reddened Objects
UniverseThe disk of the Milky Way fills the interstellar medium in the form of discrete clouds, many (∼30) light-years across. The average density of this medium is 1 hydrogen atom per cm3 (Oort limit), in the clouds—several dozen atoms, and between the clouds ...

On the Proposed Interstellar Origin of the USG 20140108 Fireball
The Astrophysical Journal, 2023 A critical review of the evidence for the interstellar origin of the USG 20140108 fireball is presented. Examining United States Government (USG) fireball velocities where independent data are available shows the former to have significant (10–15 km s ...
