ATLAS Photometry of Interstellar Object 3I/ATLAS
The Astrophysical Journal LettersWe present calibrated Asteroid Terrestrial-impact Last Alert System (ATLAS) photometry of the interstellar comet 3I/ATLAS (C/2025 N1) from March 28 through 2025 August 29, obtained with the five-site, robotic ATLAS network in the c (420–650 nm), o (560 ...

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.

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 ...

The Distribution of Earth-impacting Interstellar Objects
The Astrophysical JournalIn this paper we calculate the expected orbital elements, radiants, and velocities of Earth-impacting interstellar objects. We generate a synthetic population of ∼10 ^10 interstellar objects with M-star kinematics in order to obtain ∼10 ^4 Earth ...

Interstellar Now! Missions to Explore Nearby Interstellar Objects [PDF]
Advances in Space Research, 2022 Abstract The 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. In situ spacecraft exploration of these objects will allow the direct determination of both their structure and their chemical and isotopic composition ...

Predicting Interstellar Object Chemodynamics with Gaia
The Astronomical JournalThe interstellar object (ISO) population of the Milky Way is a product of its stars. However, what is in fact a complex structure in the solar neighborhood has traditionally in ISO studies been described as smoothly distributed.

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.

Interstellar objects outnumber Solar system objects in the Oort cloud [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2021 ABSTRACT Here, we show that the detection of Borisov implies that interstellar objects outnumber Solar system objects in the Oort cloud, whereas the reverse is true near the Sun due to the stronger gravitational focusing of bound objects. This hypothesis can be tested with stellar occultation surveys of the Oort cloud.

Detecting Interstellar Objects through Stellar Occultations [PDF]
The Astrophysical Journal Letters, 2020 Abstract Stellar occultations have been used to search for Kuiper Belt and Oort Cloud objects. We propose a search for interstellar objects based on the characteristic durations (∼0.1 s) of their stellar occultation signals and high inclination relative to the ecliptic plane.
