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.

Prospects for Backtracing 1I/`Oumuamua and Future Interstellar Objects [PDF]
The Astrophysical Journal Letters, 2017 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 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 .

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 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.
