A Comprehensive Network for the Discovery and Characterization of Interstellar Objects

Oem Trivedi, Abraham Loeb. arxiv.org. January 29, 2026.

Trivedi and Loeb propose a network for discovering and characterizing interstellar objects. Their hypothetical examples and performance estimates are conditional; the paper demonstrates no deployed network, artificial object or government programme access.

Supplied preprint text and native layouts; proposal remains unvalidated

Close Encounters of the Interstellar Kind: Examining the Capture of Interstellar Objects in Near Earth Orbit

Diptajyoti Mukherjee, Amir Siraj, Hy Trac, Abraham Loeb. arxiv.org. August 7, 2023.

Mukherjee, Siraj, Trac and Loeb simulate capture and retention of interstellar objects near Earth, then estimate populations and survey detectability under assumed incoming velocities, abundance, sizes and lifetimes. The manuscript identifies no actual captured interstellar object.

Complete supplied fourteen-page manuscript; conditional capture model

Erosion of Icy Interstellar Objects by Cosmic Rays and Implications for ‘Oumuamua

Vo Hong Minh Phan, Thiem Hoang, Abraham Loeb. arxiv.org. October 28, 2021.

Phan, Hoang and Loeb model erosion and modification of icy interstellar objects under assumed cosmic-ray, material and travel conditions. Prior observations and fits support theoretical predictions rather than new detections or demonstrated composition.

Complete supplied seven-page manuscript; conditional erosion model

Interstellar Objects Outnumber Solar System Objects in the Oort Cloud

Amir Siraj, Abraham Loeb. arxiv.org. July 22, 2021.

Siraj and Loeb infer a potentially large interstellar population from prior observations and population assumptions. The paper introduces no new data; selection, size distributions and model sensitivity limit its abundance estimates.

Complete supplied four-page manuscript; conditional abundance model

Observable Signatures of the Ejection Speed of Interstellar Objects from their Birth Systems

Amir Siraj, Abraham Loeb. arxiv.org. October 5, 2020.

Siraj and Loeb forecast interstellar-object velocity and direction distributions from conventional stellar ejection. Their estimates distinguish 12-object velocity and 180-object angular tests of two ejection models from a separate 12-object anisotropy test. Density, size, sampling and detection assumptions remain uncertain. White-dwarf, outer-cloud and interstellar-medium alternatives are retained. Discovery forecasts and an artifact conjecture are not observations. Manuscript comments and work-level grant support do not establish government access.

Detecting Interstellar Objects Through Stellar Occultations

Amir Siraj, Abraham Loeb. arxiv.org. January 8, 2020.

Siraj and Loeb propose stellar occultations as a way to find conventional interstellar objects. An idealized all-sky forecast of about one annual event depends on population, size, noise and observing assumptions. Bound Kuiper-belt and Oort-cloud populations are ordinary alternatives, with overlapping timescales. Metadata, citation, figure, axis and model discrepancies remain unresolved. This supplied preprint reports forecasts rather than detections; work-level grant support does not establish government access.

Identifying Interstellar Objects Trapped in the Solar System through Their Orbital Parameters

Amir Siraj, Abraham Loeb. arxiv.org. February 4, 2019.

Siraj and Loeb model captured interstellar minor-body orbits using inherited density, population and size assumptions. Eight catalogue objects are possible candidates, not confirmed interstellar origins or extraterrestrial artifacts. Native Oort-cloud bodies are an explicit confound. Model convergence and forecasts do not supply independent observations. Native table, selection and population-normalization qualifications remain unresolved; detection bias and original calculation gaps are preserved. Manuscript assistance and work-level funding do not establish government tasking or custody.

Comment on "Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS" [arXiv:2507.02757]

Abraham Loeb. arxiv.org. July 9, 2025.

Loeb models a population mass budget for 3I/ATLAS and offers ordinary cometary-core or rarer-population alternatives. Technological design is conditional speculation; albedo, size, selection and reservoir assumptions remain explicit, with no artificial-origin detection or independent model validation.

Complete supplied three-page v2 manuscript; model and date gaps retained

Physical Considerations for an Intercept Mission to a 1I/'Oumuamua-like Interstellar Object

Amir Siraj, Abraham Loeb, Amaya Moro-Martin, Mark Elowitz, Abigail White, Wesley A. Watters, Gary J. Melnick, Richard Cloete, Jonathan Grindlay, Frank Laukien. arxiv.org. November 3, 2022.

Siraj, Loeb and colleagues outline requirements for a proposed interstellar-object intercept. Detection and reachability forecasts depend on assumptions; material analogues and modelled spectra do not identify an artificial object.

Implications of evaporative cooling by H2 for 1I/’Oumuamua

Thiem Hoang, Abraham Loeb. arxiv.org. March 24, 2023.

Hoang and Loeb argue that evaporative cooling changes a trapped-hydrogen explanation for ’Oumuamua’s acceleration. The critique depends on selected thermal assumptions and does not establish an artificial origin.

Overview of the Galileo Project

Abraham (Avi) Loeb, Frank H. Laukien. galileo.hsites.harvard.edu. February 13, 2023.

Loeb and Laukien outline instrument-based investigations of aerial phenomena, interstellar objects and meteor fragments. The paper describes a research programme and proposed methods, rather than a confirmed anomalous discovery.

Could Solar Radiation Pressure Explain 'Oumuamua's Peculiar Acceleration?

Shmuel Bialy, Abraham Loeb. arxiv.org. October 26, 2018.

Bialy and Loeb develop a conditional radiation-pressure explanation for ’Oumuamua’s acceleration. Thin natural material and an artificial sail are discussed as possibilities; the calculations do not identify a spacecraft.
