Reduced atmospheres of post-impact worlds: The early Earth
J. P. Itcovitz, A. S. P. Rae, R. I. Citron +4
Impacts may have had a significant effect on the atmospheric chemistry of the early Earth. Reduced phases in the impactor (e.g., metallic iron) can reduce the planet's HO inven…
Asteroid Measurements at Millimeter Wavelengths with the South Pole Telescope
P. M. Chichura, A. Foster, C. Patel +141
We present the first measurements of asteroids in millimeter wavelength (mm) data from the South Pole Telescope (SPT), which is used primarily to study the cosmic microwave backgro…
Large Impacts onto the Early Earth: Planetary Sterilization and Iron Delivery
Robert I. Citron, Sarah T. Stewart
Late accretion onto the Hadean Earth included large impacts that could have influenced early habitability, either by sterilizing the planet or alternatively catalyzing the origin o…
Recovery of Meteorites Using an Autonomous Drone and Machine Learning
Robert I. Citron, Peter Jenniskens, Christopher Watkins +5
The recovery of freshly fallen meteorites from tracked and triangulated meteors is critical to determining their source asteroid families. However, locating meteorite fragments in…
The role of multiple giant impacts in the formation of the Earth-Moon system
Robert I. Citron, Hagai B. Perets, Oded Aharonson
The Earth-Moon system is suggested to have formed through a single giant collision, in which the Moon accreted from the impact-generated debris disk. However, such giant impacts ar…
Formation of Phobos and Deimos via a Giant Impact
Robert Citron, Hidenori Genda, Shigeru Ida
Although the two moons of Mars, Phobos and Deimos, have long been thought to be captured asteroids, recent observations of their compositions and orbits suggest that they may have…
