Periodic Wobble of the Post-Perihelion Jet Structure Around 3I/ATLAS
Toni Scarmato, Abraham Loeb
We analyse data on the post-perihelion morphology, including jet position angles (PAs) and coma dominated photometry of the interstellar object 3I/ATLAS. From Hubble Space Telescop…
Is the Dark Comet 1998 KY the Spacecraft Phobos 1?
Adam Hibberd, Adam Crowl, Carlos Gómez de Olea Ballester +1
Since the discovery of new kinds of celestial bodies known as , scientists have speculated about their ontology. A curious hybrid of comet and asteroid, these objects…
A Physical Model for the Ice Coma of the Interstellar, Hyperactive Comet 3I/ATLAS
Eric Keto, Abraham Loeb
A previous study suggests that the observed exponential character of the surface brightness profiles in the coma around the interstellar comet 3I/ATLAS at 4 au can be explained as…
Linking System of Jets to the Non-Gravitational Acceleration of 3I/ATLAS
Toni Scarmato, Abraham Loeb
Building on the jet morphology and periodic wobble analysis of 3I/ATLAS in Scarmato & Loeb (2026), we link observed jet position angles (PAs) and the non-gravitational acceleration…
Inferring the mass and size of 3I/ATLAS from its non-gravitational acceleration
Valentin Thoss, Abraham Loeb, Andreas Burkert
Observations of the interstellar object 3I/ATLAS have revealed a strong production of gas and dust near perihelion, together with rapid brightening. The outgassing from the nucleus…
The Physics of Cometary Anti-tails as Observed in 3I/ATLAS
Eric Keto, Abraham Loeb
Observations of interstellar comet 3I/ATLAS at 3.8 au show an elongated coma similar to a cometary tail but pointing in the direction of the Sun, possibly the first instance of thi…
