ATLAS Photometry of Interstellar Object 3I/ATLAS

The Astrophysical Journal Letters
We 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 ...

Interstellar dust within the life cycle of the interstellar medium [PDF]

EPJ Web of Conferences, 2012
Cosmic dust is omnipresent in the Universe. Its presence influences the evolution of the astronomical objects which in turn modify its physical and chemical properties.

Interstellar objects in a galactic context [PDF]

Interstellar objects (ISOs) form a vast Galaxy-spanning population with an number density ∼ 1015 pc−3 in the Solar neighbourhood. Though only two members of this population have been observed, 1I/‘Oumuamua and 2I/Borisov, the Vera C. Rubin’s Legacy Survey of Space and Time (LSST) which begins later this year is expected to increase our sample of known ...

He Awa Whiria: The Tidal Streams of Interstellar Objects [PDF]

The Astrophysical Journal
Upcoming 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.

Strength Ratios of Diffuse Interstellar Bands in Slightly Reddened Objects [PDF]

Universe
The disk of the Milky Way fills the interstellar medium in the form of discrete clouds, many (∼30) light-years across. The average density of this medium is 1 hydrogen atom per cm3 (Oort limit), in the clouds—several dozen atoms, and between the clouds ...

Identifying Interstellar Object Impact Craters

The Planetary Science Journal, 2022
Abstract The discoveries of two interstellar objects (ISOs) in recent years have generated significant interest in constraining their physical properties and the mechanisms behind their formation. However, their ephemeral passages through our solar system permitted only incomplete characterization.

Predicting Interstellar Object Chemodynamics with Gaia

The Astronomical Journal
The 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.

Candidate Captured Interstellar Objects in the Solar System [PDF]

Interstellar objects (ISOs) can become gravitationally bound to the solar system, enabling multiple observations. If these bound ISOs exist, they provide valuable opportunities to generalize models of planetesimal formation, composition, and ejection beyond our solar system.
