Exposing metal and silicate charges to electrical discharges: Did chondrules form by nebular lightning?
C. Güttler, T. Poppe, J. T. Wasson +1
In order to investigate the hypothesis that dust aggregates were transformed to meteoritic chondrules by nebular lightning, we exposed silicatic and metallic dust samples to electr…
The Physics of Protoplanetesimal Dust Agglomerates II. Low Velocity Collision Properties
Doreen Langkowski, Jens Teiser, Jürgen Blum
For the investigation of collisions among protoplanetesimal dust aggregates, we performed microgravity experiments in which the impacts of high-porosity mm-sized dust aggregates in…
Biomarker Response to Galactic Cosmic Ray-Induced NOx and the Methane Greenhouse Effect in the Atmosphere of an Earthlike Planet Orbiting an M-Dwarf Star
John Lee Grenfell, Jean-Mathias Griessmeier, Beate Patzer +6
Planets orbiting in the habitable zone (HZ) of M-Dwarf stars are subject to high levels of galactic cosmic rays (GCRs) which produce nitrogen oxides in earthlike atmospheres. We in…
The 10 m infrared band of silicate dust: A laboratory study comparing the aerosol and KBr pellet techniques
A. Tamanai, H. Mutschke, J. Blum +1
The profile of the silicate 10 m IR band contains important information about the evolutional stage of dust in circumstellar environments and the possible ongoing process of pla…
