A Fission-Powered Interstellar Precursor Mission [PDF]
An 'interstellar precursor mission' lays the groundwork for eventual interstellar exploration by studying the interstellar medium and by stretching technologies that have potential application for eventual interstellar exploration.

The Implications of ‘Oumuamua on Panspermia
Panspermia is the hypothesis that life originated on Earth from the bombardment of foreign interstellar ejecta harboring polyextremophile microorganisms. Since the 2017 discovery of the interstellar body ‘Oumuamua (1I/2017 U1) by the Pan-STARRS telescope,

Predicting Interstellar Object Chemodynamics with Gaia
Abstract 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.

The Journey of Interstellar Dust
Interstellar dust particles undergo a complex journey in space. It commences with their formation in stellar outflows or outbursts, but may end in very different ways. Their fates range from sudden "death by destruction" promptly after their formation to

Interstellar Objects in the Context of the Milky Way’s Thin and Thick Disks
The division of the Milky Way’s disk into “thin” and “thick” components is a common practice, but one that is often ambiguously defined. The two ways of dividing stars are not equivalent: many stars belonging to the stellar population at high [α/Fe] (the

Simulating molecular cloud regulated star formation in Galaxies [PDF]
This thesis is primarily concerned with understanding the process of galaxy formation via the simulation of the interstellar medium, star formation and supernova feedback.

Interstellar objects in a galactic context
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 ...

Isotopic Fractionation in Interstellar Chemistry [PDF]
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 ...
