Cataclysmic variables as probes of x-ray properties of interstellar grains [PDF]

open access: yes, 1983
Interstellar-grain properties have previously been probed at wavelengths ranging from the infrared to the ultraviolet. Recent work by other authors has shown that we may also observe the effects of scattering by such grains at x-ray wavelengths.

A Case Study of Interstellar Material Delivery: α Centauri

open access: yesThe Planetary Science Journal
Interstellar material has been discovered in our solar system, yet its origins and details of its transport are unknown. Here, we present α Centauri as a case study of the delivery of interstellar material to our solar system.

Spectral Characteristics of Interstellar Object 3I/ATLAS from SOAR Observations

open access: yesThe Astrophysical Journal Letters
Interstellar objects (ISOs) provide unique insights into the building blocks and conditions of extrasolar planetary systems. The newly discovered object, 3I/ATLAS (C/2025 N1), represents the third known ISO after 1I/’Oumuamua and 2I/Borisov.

Nucleus and Postperihelion Activity of Interstellar Object 3I/ATLAS Observed by the Hubble Space Telescope

open access: yesThe Astrophysical Journal Letters
We report the detection of the nucleus of interstellar object 3I/ATLAS, using a nucleus extraction technique on Hubble Space Telescope (HST) observations taken between 2025 December and 2026 January.

Capture of Interstellar Objects and Binaries

open access: yes
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.

The Feasibility of a Spacecraft Flyby with the Third Interstellar Object 3I/ATLAS from Earth or Mars

open access: yesThe Astrophysical Journal
We investigate the feasibility of a spacecraft mission to conduct a flyby of 3I/ATLAS, the third macroscopic interstellar object discovered on 2025 July 1, as it traverses the solar system.
