Anticipating the DART impact: Orbit estimation of Dimorphos using a simplified model
Shantanu P. Naidu, Steven R. Chesley, Davide Farnocchia +5
We used the times of occultations and eclipses between the components of the 65803 Didymos binary system observed in its lightcurves from 2003-2021 to estimate the orbital paramete…
Sublimation-Driven Activity in Main-Belt Comet 313P/Gibbs
Henry H. Hsieh, Olivier Hainaut, Bojan Novakovic +15
We present an observational and dynamical study of newly discovered main-belt comet 313P/Gibbs. We find that the object is clearly active both in observations obtained in 2014 and…
Properties of outer solar system pebbles during planetesimal formation from meteor observations
Peter Jenniskens, Paul R. Estrada, Stuart Pilorz +42
In the late stages of accretion leading up to the formation of planetesimals, particles grew to pebbles the size of 1-mm to tens of cm. That is the same size range that dominates t…
Unmasking (44) Nysa: Evidence for a trilobate structure
Kate Minker, Anthony Berdeu, Gianluca Li Causi +16
Context. (44) Nysa is one of the largest known E-type asteroids. Light curve inversion models have indicated that it may have an elongated shape commonly found in large binary syst…
Dynamic Trajectory Analysis of Meteoroids Showing Minimal Deceleration
Thomas Stevenson, Ellie Sansom, Hadrien Devillepoix +8
Meteoroids decelerate and ablate as they descend through the atmosphere, however a portion of instrumentally observed meteors show little measurable deceleration and remain poorly…
No Detectable H3+ Emission from the Atmospheres of Hot Jupiters
Evgenya Shkolnik, Eric Gaidos, Nick Moskovitz
H emission is the dominant cooling mechanism in Jupiter's thermosphere and a useful probe of temperature and ion densities. The H ion is predicted to form in the thermo…
