Exporting Terrestrial Life Out of the Solar System with Gravitational Slingshots of Earthgrazing Bodies
Amir Siraj, Abraham Loeb
Exporting terrestrial life out of the Solar System requires a process that both embeds microbes in boulders and ejects those boulders out of the Solar System. We explore the possib…
An Argument for a Kilometer-Scale Nucleus of C/2019 Q4
Amir Siraj, Abraham Loeb
C/2019 Q4 (Borisov), discovered by Gennady Borisov on August 30, 2019, is tentatively an interstellar comet. We show that a kilometer-scale nucleus would provide consistency with b…
Radio Flares from Collisions of Neutron Stars with Interstellar Asteroids
Amir Siraj, Abraham Loeb
We propose that collisions between neutron stars and interstellar asteroids, such as `Oumuamua, could power observable radio flares in the Milky Way galaxy. We find the rate of suc…
A Real-Time Search for Interstellar Impacts on the Moon
Amir Siraj, Abraham Loeb
The discovery of `Oumuamua and CNEOS 2014-01-08 allowed for a calibration of the impact rate of interstellar objects. We propose a new telescope in lunar orbit to study in real-tim…
Halo Meteors
Amir Siraj, Abraham Loeb
The stellar halo contains some of the oldest stars in the Milky Way galaxy and in the universe. The detections of `Oumuamua, CNEOS 2014-01-08, and interstellar dust serve to calibr…
Probing Extrasolar Planetary Systems with Interstellar Meteors
Amir Siraj, Abraham Loeb
The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the impact rate of interstellar meteors of its siz…
The 2019 Discovery of a Meteor of Interstellar Origin
Amir Siraj, Abraham Loeb
The earliest confirmed interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects…
