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 .

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.

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.

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.

Disk and Envelope Streamers of the GGD 27-MM1 Massive Protostar
The Astrophysical Journal, 2023 We present new Atacama Large Millimeter/submillimeter Array 0.98 mm observations of the continuum emission and several molecular lines toward the high-mass protostellar system GGD 27-MM1, driving the HH 80-81 radio jet.

Localizing the First Interstellar Meteor with Seismometer Data
Signals, 2023 The first meter-scale interstellar meteor (IM1) was detected by US government sensors in 2014, identified as an interstellar object candidate in 2019, and confirmed by the Department of Defense (DoD) in 2022.

The Kinematic Age of 3I/ATLAS and Its Implications for Early Planet Formation
The Astrophysical Journal LettersThe 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.

Near-discovery Observations of Interstellar Comet 3I/ATLAS with the NASA Infrared Telescope Facility
The Astrophysical Journal LettersInterstellar 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 ...

The Planetary Science JournalWe observed interstellar object 3I/ATLAS = C/2025 N1 (ATLAS) on 2025 December 9 UT with the VIRUS spectrograph on the Hobby–Eberly Telescope. VIRUS is a low spectral resolving power, multi-integral field unit (IFU), optical spectrograph. We used a single
