Solar sail mission applications and future advancement [PDF]
, 2010 Solar sailing has long been envisaged as an enabling technology. The promise of open-ended missions allows consideration of radically new trajectories and the delivery of spacecraft to previously unreachable or unsustainable observation outposts.

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

High-drag Interstellar Objects and Galactic Dynamical Streams
The Astrophysical Journal Letters, 2019 Abstract The nature of 1I/’Oumuamua (henceforth, 1I), the first interstellar object (ISO) known to pass through the solar system, remains mysterious. Feng & Jones noted that the incoming 1I velocity vector “at infinity” ( ) is close to the motion of the Pleiades ...

Isotopic Fractionation in Interstellar Chemistry [PDF]
, 2018 Anomalously fractionated isotopic material is found in many primitive Solar System objects, such as meteorites and comets. It is thought, in some cases, to trace interstellar matter that was incorporated into the Solar Nebula without undergoing ...

Evidences of Two Merging Elongated Filaments Associated with AGAL323.444+0.096 and Star Formation
The Astrophysical JournalWe study the structure, kinematics, and star-forming activity of filamentary cloud F-NE associated with AGAL323.444+0.096 using ^13 CO ( J = 2–1) molecular line and continuum data from the far-infrared to near-infrared.

The Astrophysical JournalWe present an observational study of the S284-RE region, a low-metallicity area associated with the extended S284 H ii region. A thermally supercritical filament (mass ∼2402 M _⊙ and length ∼8.5 pc) is investigated using the Herschel column density map ...

Investigation into Triggered Star Formation by Radiative Driven Implosion [PDF]
, 2016 When massive stars form, they emit strong, hydrogen ionising radiation fields into their molecular cloud environment, forming HII regions. This is believed to be capable of inducing effects which can trigger further star formation through a process known

Interstellar Isotopes: Prospects with ALMA [PDF]
, 2010 Cold molecular clouds are natural environments for the enrichment of interstellar molecules in the heavy isotopes of H, C, N and O. Anomalously fractionated isotopic material is found in many primitive Solar System objects, such as meteorites and comets,

Testable Predictions for Interstellar Object 3I
We present specific, quantifiable predictions for the behavior of interstellar object 3I/ATLAS during its December 2025 Earth flyby and March 2026 Jupiter encounter, based on a theory proposing that space is divided into Matter-Dominated Space (MDS), Antimatter-Dominated Space (ADS), and Pure Gravitational Wave Space (PGWS).
