Es gibt neues über Exo-Monde und deren Häufigkeit zu berichten:
Anbei ein aktueller Bericht aus Centauri Dreams:
http://www.centauri-dreams.org/?p=18183
.....Under these restrictive conditions we identify 88 moon forming events in 64 simulations… On average, every simulation gives three terrestrial planets with different masses and orbital characteristics and we have roughly 180 planets in total. Hence, almost one in two planets has an obliquity stabilizing satellite in its orbit. If we focus on Earth-Moon like systems, where we have a massive planet with a final mass larger than half of an Earth mass and a satellite larger than half a Lunar mass, we identify 15 moon forming collisions. Therefore, 1 in 12 terrestrial planets is hosting a massive moon......
Damit wird deutlich, dass große Monde wie wir einen haben gar nicht so unwahrscheinlich sind. Eine Chance von 1 zu 12 halte ich für sehr gut!
Weiter Preprints dann hier :
