On the dynamical history of the interstellar object 'Oumuamua?
, 2017 1I/2017 U1 'Oumuamua is the first interstellar object recorded inside the Solar System. We try to answer the main question: where does it come from? To this aim we searched for close encounters between 'Oumuamua and all nearby stars with known kinematic data during their past motion.We had checked over 200 thousand stars and found just a handful of ...

A Catalogue of Interstellar Material Delivery from Nearby Debris Disks
The Planetary Science JournalWe modeled the trajectories of material ejected from 20 nearby debris disk stars, including ϵ Eridani (Ran), Vega, Fomalhaut, and β Pictoris, within a simulated Milky Way potential in order to quantify their contribution to the population of interstellar

The Cosmic Sulfur Depletion Problem Extends to Interstellar Object 3I/ATLAS
The Astrophysical Journal LettersConstraining the sulfur reservoirs of interstellar objects provides essential clues to the nature of sulfur species in protoplanetary disks and interstellar molecular clouds and a potential solution to the cosmic sulfur depletion problem. Observations of

Detecting Dark Objects with Plasma Microlensing by Their Gravitational Wakes
The Astrophysical JournalA moving mass makes a gravitational wake in the partially ionized interstellar medium, which acts as a lens for radio-frequency light. Consequently, plasma microlensing could complement gravitational microlensing in the search for invisible massive ...

Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
The Astrophysical Journal LettersWe report initial observations aimed at the characterization of a third interstellar object. This object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered on 2025 July 1 UT and has an orbital eccentricity of e ∼ 6.1, perihelion of q ∼ 1.36 au, inclination

Asymptotic giant branch-stars in the GLIMPSE database
Astronomy & AstrophysicsAims. In the preceding paper (paper I) we showed that the GLIMPSE database contains millions of asymptotic giant branch (AGB) stars. Their nature follows from two properties: the objects have the same color after correction for interstellar extinction ...

Precovery Observations of 3I/ATLAS from TESS Suggest Possible Distant Activity
The Astrophysical Journal Letters3I/ATLAS is the third macroscopic interstellar object detected traversing the solar system. Since its initial discovery on UT 2025 July 1, hundreds of hours on a range of observational facilities have been dedicated to measuring the physical properties ...
