Prospects for Backtracing 1I/‘Oumuamua and Future Interstellar Objects [PDF]
Astrophysical Journal Letters, 2018 Abstract 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 and subsequently arriving at the solar system. This paper discusses necessary

Synthetic Detections of Interstellar Objects with the Rubin Observatory Legacy Survey of Space and Time [PDF]
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 .

Rendez-vous with massive interstellar objects, as triggers of destabilization [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT We study how close passages of interstellar objects of planetary and substellar masses may affect the immediate and long-term dynamics of the Solar system. We consider two nominal approach orbits, namely the orbits of actual interstellar objects 1I/’Oumuamua and 2I/Borisov, assuming them to be typical or representative for ...

An Origin of Narrow Extended Structure in the Interstellar Medium: An Interstellar Contrail Created by a Fast-moving Massive Object [PDF]
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.

Galactic trajectories of interstellar objects 1I/’Oumuamua, 2I/Borisov, and 3I/ATLAS
Astronomy & AstrophysicsAims. The first interstellar objects, 1I/’Oumuamua, 2I/Borisov, and 3I/ATLAS, were discovered over the past decade. Methods. We follow the trajectories of known interstellar objects in the gravitational potential of the Milky Way galaxy to constrain ...

X-Rays Trace the Volatile Content of Interstellar Objects
The Astrophysical Journal, 2023 The nondetection of a coma surrounding 1I/‘Oumuamua, the first discovered interstellar object (ISO), has prompted a variety of hypotheses to explain its nongravitational acceleration.

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 ...

The Planetary Science Journal, 2023 In this paper, we present an open-source software (Simulator of Asteroid Malformation Under Stress, SAMUS ) that simulates constant-density, constant-viscosity liquid bodies subject to tidal forces for a range of assumed viscosities and sizes.
