We suggest that the kinematics and properties of interstellar object A/2017 U1 point towards its formation in a protoplanetary disk in the ~45 Myr-old Carina or Columba young stellar associations, and subsequent ejection with a low peculiar velocity (1-2 km/sec) during or soon after planet formation inside the ice line. This scenario predicts that the Solar System will encounter more such objects with radiants similar to that of A/2017 U1.

On the dynamical history of the recently discovered interstellar object A/2017 U1 - where does it come from?
A/2017 U1 is the first interstellar object recorded inside the Solar System. We try to answer the obtrusive question: where does it come from? After a careful search in the close vicinity of the Sun
The origin of interstellar asteroidal objects like 1I/2017 U1
With the recently discovered interstellar object 1I/2017U1 (1I/'Oumuamua) we have to realize that the Solar System is not isolated, but part of a larger environment with which we interact. We compare
Implications of Captured Interstellar Objects for Panspermia and Extraterrestrial Life
We estimate the capture rate of interstellar objects by means of three-body gravitational interactions. We apply this model to the Sun-Jupiter system and the Alpha Centauri A\&B binary system, and
Investigating the dynamical history of the interstellar object 'Oumuamua
Here we try to find the origin of 1I/2017 U1 ’Oumuamua, the first interstellar object recorded inside the solar system. To this aim, we searched for close encounters between ’Oumuamua and all nearby
What and whence 1I/`Oumuamua: a contact binary from the debris of a young planetary system?
The first confirmed interstellar interloper in our Solar System, 1I/`Oumuamua, is likely to be a minor body ejected from another star, but its brief flyby and faintness made it difficult to study.
Identifying Interstellar Objects Trapped in the Solar System through Their Orbital Parameters
The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size and an estimation
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
A general method for assessing the origin of interstellar small bodies: the case of 1I/2017 U1 ('Oumuamua)
With the advent of more and deeper sky surveys, the discovery of interstellar small objects entering into the Solar System has been finally possible. In October 19, 2017, using observations of the
The fate of planetesimal discs in young open clusters: implications for 1I/’Oumuamua, the Kuiper belt, the Oort cloud, and more
We perform N-body simulations of the early phases of open cluster evolution including a large population of planetesimals, initially arranged in Kuiper-belt like discs around each star. Using a
Kinematics of the Interstellar Vagabond 1I/'Oumuamua (A/2017 U1)
