The properties of the first-discovered interstellar object (ISO), 1I/2017 (‘Oumuamua), differ from both solar system asteroids and comets, casting doubt on a protoplanetary disk origin. In this study, we investigate the possibility that it formed with a substantial H2 ice component in the starless core of a giant molecular cloud. While interstellar solid hydrogen has yet to be detected, this constituent would explain a number of the ISO’s properties. We consider the relevant processes required… 
Constraints on the Occurrence of ‘Oumuamua-Like Objects
At present, there exists no consensus in the astronomical community regarding either the bulk composition or the formation mechanism for the interstellar object 1I/2017 U1 (‘Oumuamua). With the goal
The Volatile Carbon-to-oxygen Ratio as a Tracer for the Formation Locations of Interstellar Comets
Based on the occurrence rates implied by the discoveries of 1I/‘Oumuamua and 2I/Borisov, the forthcoming Rubin Observatory Legacy Survey of Space and Time (LSST) should detect ≥one interstellar

Molecular hydrogen normally has only weak, quadrupole transitions between its rovibrational states, but in a static electric field it acquires a dipole moment and a set of allowed transitions. Here

The recently discovered population of interstellar objects presents us with the opportunity to characterize material from extrasolar planetary and stellar systems up close. The forthcoming Vera C.
Evidence Suggesting That ‘Oumuamua Is the ∼30 Myr Old Product of a Molecular Cloud
The appearance of interstellar objects (ISOs) in the solar system—and specifically the arrival of 1I/‘Oumuamua—points to a significant number density of free-floating bodies in the solar

Destruction of Molecular Hydrogen Ice and Implications for 1I/2017 U1 (‘Oumuamua)
The first interstellar object observed in our solar system, 1I/2017 U1 (‘Oumuamua), exhibited a number of peculiar properties, including extreme elongation and acceleration excess. Recently, Seligman
The gas-grain interaction in the interstellar medium - Thermal accommodation and trapping
A numerical model is developed for calculating thermal accommodation coefficients ..cap alpha../sub T/ and trapping fractions f/sub t/ for gases incident upon solid surfaces. The numerical method is
Coagulation of grains in static and collapsing protostellar clouds
The wavelength dependence of extinction in the diffuse interstellar medium implies that it is produced by particles of dominant size of approximately 10(exp -5) cm. There is some indication that in
Explaining the elongated shape of 'Oumuamua by the Eikonal abrasion model
The photometry of the minor body with extrasolar origin (1I/2017 U1) 'Oumuamua revealed an unprecedented shape: Meech et al. (2017) reported a shape elongation b/a close to 1/10, which calls for

Solid H2 in the interstellar medium
Context. Condensation of H 2 in the interstellar medium (ISM) has long been seen as a possibility, either by deposition on dust grains or thanks to a phase transition combined with self-gravity. H 2
Interstellar Interlopers: Number Density and Origin of ‘Oumuamua-like Objects
We provide a calculation of Pan-STARRS’ ability to detect objects similar to the interstellar object 1I/2017 U1 (hereafter ‘Oumuamua), including the most detectable approach vectors and the effect of
Evidence that 1I/2017 U1 (‘Oumuamua) was Composed of Molecular Hydrogen Ice
‘Oumuamua (I1 2017) was the first macroscopic (l ∼ 100 m) body observed to traverse the inner solar system on an unbound hyperbolic orbit. Its light curve displayed strong periodic variation, and it

The low velocity of interstellar asteroid 1I/’Oumuamua with respect to our galaxy’s local standard of rest implies that it is young. Adopting the young age hypothesis, we assess possible origin
