Planetary Group Seminar: Thermal and mechanical properties in the near-surface of comet 67P/Churyumov-Gerasimenko from Rosetta (N. Attree)

  • Datum: 04.10.2018
  • Uhrzeit: 11:00 - 12:00
  • Vortragender: Nicolas Attree
  • Earth and Planetary Observation Centre, University of Stirling
  • Ort: MPS
  • Raum: Auditorium
  • Gastgeber: Urs Mall

Measuring cometary material strengths and other mechanical properties can help put constraints on the formation and evolution of these, likely primordial, bodies. I will present results from two pieces of work investigating the near surface of 67P/Churyumov-Gerasimenko from Rosetta: an observational study of overhanging cliffs from OSIRIS images, and modelling work on thermo-mechanical fracturing. These studies support a low bulk strength, primordial model of comets but with a significantly thermally modified surface layer, with greater strength, as found by the Philae lander. [mehr]

Planetary Group Seminar: Atmospheres and Climates of Rocky Exoplanets: What Earth tells us about them, and what they can teach us about Earth (D. Koll)

Rocky exoplanets are extremely common in the galaxy, but we currently know little about most of them. What are these planets like? I will discuss how theories originally developed for Earth can shed new light on exoplanets and, conversely, how the study of exoplanets can help us better understand Earth. [mehr]

Sehnsuchtsplanet Mars: Mögliches Leben auf dem Mars? Ja, aber welches? (K. Finster)

Planetary Group Seminar: Erosion of silicates and its implications for Martian surface habitability and chemistry (K. Finster)

The harsh and detrimental Martian surface conditions are generally associated with the radiation environment that is dominated by highly cytotoxic UV radiation. UV radiation both directly affects living organisms through modifications of the genetic code as well as indirectly through peroxidation of proteins and membrane lipids by reactive oxygen species (ROS) formation including H2O2 that are cytotoxic. I will introduce an alternative mechanism that equally results in ROS formation and can account for direct and indirect cell death: ABRASION BY SALTATION. [mehr]
