Atmospheric Collapse And re-inflation Through Impacts For Terrestrial Planets Around M Dwarfs
Detection of an atmosphere around a terrestrial exoplanet will be a major milestone in the field, but our observational capacities are biased towards to tidally locked, close-in planets orbiting M-dwarf […]
Pseudo-panspermia of Phosphorus Species on the Early Earth
In the Earth system, Phosphorus (P) does not form a single phase, but mostly combines into compounds forming multiple minerals. Phosphate (P+5) is the majority P species in the Earth’s […]
Re-accretion of Giant Impact Ejecta Can Drive Significant Atmospheric Erosion on Terrestrial Planets
Giant impacts, the collisions between planetary embryos, play a crucial role in sculpting the planets and their orbital architectures.
The Depletion Of The Asteroid Belt And The Impact History Of The Earth
We have evaluated the rate at which the asteroid belt is losing material, and how it splits between macroscopic bodies and meteoritic dust.
Multiple Giant Impacts and Chemical Equilibria: An Integrated Approach to Rocky Planet Formation
During the formation of rocky planets, the surface environments of growing protoplanets were dramatically different from those of present-day planets.
Shocked Quartz At The Younger Dryas Onset Supports Cosmic Airbursts/Impacts
Shocked quartz grains are an accepted indicator of crater-forming cosmic impact events, which also typically produce amorphous silica along the fractures. Furthermore, previous research has shown that shocked quartz can […]
Piecing Together Formic Acid Isomerism In Dark Clouds. Detection Of Cis-formic Acid In TMC-1 And Astrochemical Modeling
The presence of molecular isomers in interstellar environments has become a topic of growing interest within the astrochemical community.
Discovery Links Microbial Colonization To An Ancient Meteorite Crater
In a scientific breakthrough with cosmic implications, researchers have, for the first time, precisely dated the emergence of microbial life within a meteorite impact crater—revealing that life not only survives […]
Isotopic Composition Of Cometary Water And The Origin Of Earth’s Oceans
Studies of the water content and isotopic composition of water-rich asteroids and comets are of key interest for understanding the late accretion stage of the Solar System cometary and chondritic […]
