Abstract Gas and dust outbursts are recurring phenomena on comets, offering critical insights into their subsurface activities. On comet 67P/Churyumov-Gerasimenko, two distinct outburst types have been identified: CO2-dominated ”summer fireworks” near perihelion water-driven events often linked to cliff collapses outside the period. While thought originate from gas cavities, properties of these cavities remain poorly understood. In this study, we modelled outgassing dynamics velocities using...
Terrestrial (carbon-based) biochemistry relies on chemical functionality introduced by heteroatoms. Among them, the nitrogen atom (N) defines (bio)chemical properties of crucial building blocks life such as amino acids (AAs) and nucleobases (NBs). However, it has not been clear until today whether these Earth were synthesized from simple prebiotic molecules young planet itself or rather delivered impacting material. Comets only carry some most pristine original material in our Solar System,...
A time-of-flight mass spectrometer (TOF-MS) separates charged particles by their mass-per-charge ratio on the basis of transit times through an electric field. For accurate determination, ions must be guided from source inlet, ion-optical system, and onto detector as a beam with controlled, narrow opening angle. This requires careful dimensioning electrodes computation applied fields to control deflection achieve both spatial temporal focusing across entire plane. The primary goal this work...
