Varying Water Activity and Momentum Transfer on Comet 67P/Churyumov-Gerasimenko From its non-gravitational Forces and Torques
We investigate the ability of a simultaneous fitting of comet 67P/Churyumov-Gerasimenko’s non-gravitational forces, torques and total water-outgassing rate, as observed by Rosetta, to constrain complex thermophysical models of cometary material.

Chemical Composition of Comets C/2021 A1 (Leonard) and C/2022 E3 (ZTF) From Radio Spectroscopy and the Abundance of HCOOH and HNCO in Comets
We present the results of a molecular survey of long period comets C/2021 A1 (Leonard) and C/2022 E3 (ZTF). Comet C/2021 A1 was observed with the IRAM 30-m radio telescope […]

Accelerating Giant Impact Simulations With Machine Learning
Constraining planet formation models based on the observed exoplanet population requires generating large samples of synthetic planetary systems, which can be computationally prohibitive.

The Pre-perihelion Evolution of the Activity of Comet C/2017 K2 (PANSTARRS) During the Water Ice-line Crossover
Comets, relics from the early solar system, consist of dust and ice. The ice sublimates as comets approach the Sun, ejecting dust from their nuclei seen as activity. Different volatiles […]

Exocomet Orbital Distribution Around Beta Pictoris
The 23 Myr young star β Pictoris is a laboratory for planet formation studies given its observed debris disk, its two directly imaged super-Jovian planets, and the evidence of transiting […]

Destruction Of Interstellar Methyl Cyanide (CH3CN) Via Collisions With He+ Ions
Methyl cyanide is one of the simplest interstellar complex organic molecules, widely detected in young solar analogues, shocked regions, protoplanetary disks and comets. CH3CN can be considered a key species […]

The Building Materials For Water-rich Planets In The Early Solar System
Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These so-called […]
