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, \cite{Seligman:2020vb} proposed that the object was made out of molecular hydrogen (H$_{2}$) ice. The question is whether H$_2$ objects could survive their travel from the birth sites to the solar system. Here we study destruction processes of icy H$_2$ objects through their journey from giant molecular…

Assessing the Formation of Solid Hydrogen Objects in Starless Molecular Cloud Cores
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
1I/‘Oumuamua as an N 2 Ice Fragment of an exo‐Pluto Surface: I. Size and Compositional Constraints
The origin of the interstellar object 1I/'Oumuamua has defied explanation. We perform calculations of the non-gravitational acceleration that would be experienced by bodies composed of a range of
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
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
On the Possibility of an Artificial Origin for `Oumuamua
Science offers the privilege of following evidence, not prejudice. The first interstellar object discovered near Earth, `Oumuamua, showed half a dozen anomalies relative to comets or asteroids in the
Preliminary Evidence That Protoplanetary Disks Eject More Mass Than They Retain
If interstellar objects originate in protoplanetary disks, they can be used to calibrate the fraction of mass that such disks eject. The discoveries of interstellar objects 1I/‘Oumuamua and
Anomalous Sun Flyby of 1I/2017 U1 (`Oumuamua)
The findings of Micheli et al. (Nature2018, 559, 223–226) that 1I/2017 U1 (`Oumuamua) showed anomalous orbital accelerations have motivated us to apply an impact model of gravity in search for an
Constraining the orientation of the spin axes of extrasolar minor bodies 1I/2017 U1 (‘Oumuamua) and 2I/Borisov
Context. The orientation of the spin axis of a comet is defined by the values of its equatorial obliquity and its cometocentric longitude of the Sun. These parameters can be computed from the
Observable Signatures of the Ejection Speed of Interstellar Objects from Their Birth Systems
`Oumuamua and Borisov were the first two interstellar objects confirmed in the Solar system. The upcoming commencement of the Vera C. Rubin Observatory's Legacy Survey of Space of Time (LSST) will
Oumuamuas Passing through Molecular Clouds
The detections of 1I/Oumuamua and 2I/Borisov within just two years demonstrate impressively that interstellar objects (ISOs) must be common in the Milky Way. Once released from their parent system,

Non-gravitational acceleration in the trajectory of 1I/2017 U1 (‘Oumuamua)
TLDR
‘Oumuamua—the first known interstellar object to have entered the Solar System—is probably a comet, albeit with unusual dust and chemical properties owing to its origin in a distant solar system.

TLDR
