NEO Population, Velocity Bias, and Impact Risk from an ATLAS Analysis
A. N. Heinze, Larry Denneau, John L. Tonry +9
We estimate the total population of near-Earth objects (NEOs) in the Solar System, using an extensive, `Solar System to pixels' fake-asteroid simulation to debias detections of rea…
Investigating Gravitational Collapse of a Pebble Cloud to form Transneptunian Binaries
James E. Robinson, Wesley C. Fraser, Alan Fitzsimmons +1
Context. A large fraction of transneptunian objects are found in binary pairs, ~30% in the cold classical population between ~39 and ~48 AU. Observationally, these bi…
The Transient Jupiter Trojan-Like Orbit of P/2019 LD2 (ATLAS)
Henry H. Hsieh, Alan Fitzsimmons, Bojan Novakovic +2
Comet P/2019 LD2 has orbital elements currently resembling those of a Jupiter Trojan, and therefore superficially appears to represent a unique opportunity to study the volatile co…
Exocomets from a Solar System Perspective
Paul A. Strøm, Dennis Bodewits, Matthew M. Knight +24
Exocomets are small bodies releasing gas and dust which orbit stars other than the Sun. Their existence was first inferred from the detection of variable absorption features in ste…
Discovery of a pre-cataclysmic binary with unusual chromaticity of the eclipsed white dwarf by the GPX Survey
Vadim Krushinsky, Paul Benni, Artem Burdanov +14
We report the discovery of a relatively bright eclipsing binary system, which consists of a white dwarf and a main sequence K7 star with clear signs of chromospheric and spot activ…
Interstellar comet 2I/Borisov as seen by MUSE: C, NH and red CN detections
Michele T. Bannister, Cyrielle Opitom, Alan Fitzsimmons +11
We report the clear detection of C and of abundant NH in the first prominently active interstellar comet, 2I/Borisov. We observed 2I on three nights in November 2019 at opt…
