A Near-Earth Object Model Calibrated to Earth Impactors
Sophie E. Deam, Hadrien A. R. Devillepoix, David Nesvorný +16
The population of Earth-impacting meteoroids and its size-dependent orbital elements are key to understanding the origin of meteorites and informing on planetary defence efforts. O…
Starkiller: subtracting stars and other sources from IFU spectroscopic data through forward modeling
Ryan Ridden-Harper, Michele T. Bannister, Sophie E. Deam +1
We present starkiller, an open-source Python package for forward-modeling flux retrieval from integral field unit spectrograph (IFU) datacubes. Starkiller simultaneously provides s…
Recent Chemo-morphological Coma Evolution of Comet 67P/Churyumov-Gerasimenko
Brian P. Murphy, Cyrielle Opitom, Colin Snodgrass +5
We present VLT/MUSE observations of comet 67P/Churyumov-Gerasimenko during its 2021 perihelion passage, from which we generated simultaneous maps of dust, [OI], C, NH, and…
Snapshot of a new interstellar comet: 3I/ATLAS has a red and featureless spectrum
Cyrielle Opitom, Colin Snodgrass, Emmanuel Jehin +19
The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and compositi…
A portrait throughout perihelion of the NH-rich interstellar comet 2I/Borisov
Sophie E. Deam, Michele T. Bannister, Cyrielle Opitom +12
The interstellar comet 2I/Borisov is the first interstellar object where compositional characterisation was possible throughout its entire perihelion passage. We report all 16 epoc…
Perihelion history and atmospheric survival as primary drivers of the Earth`s meteorite record
Patrick M. Shober, Hadrien A. R. Devillepoix, Jeremie Vaubaillon +7
Models predict that more than half of all impacting meteoroids should be carbonaceous, reflecting the abundance of carbon-rich asteroids in the main belt and near-Earth space. Yet…
