A size comparison of the planets of the TRAPPIST-1 system, lined up in order of increasing distance from their host star. The planetary surfaces are portrayed with an artist’s impression of their potential surface features, including water, ice, and atmospheres.

Enhanced interplanetary panspermia in the TRAPPIST-1 system

https://arxiv.org/pdf/1703.00878.pdf

We present a simple model for estimating the probability of interplanetary panspermia in the recently discovered system of seven planets orbiting the ultracool dwarf star TRAPPIST-1, and find that panspermia is potentially orders of magnitude more likely to occur in the TRAPPIST-1 system compared to the Earth-to-Mars case.

Nos apresentamos um simples modelo para estimar a probabilidade de panspermia interplanetaria no recente descoberto Sistema de sete planetas orbitando a ultrafria estrela ana TRAPPIST-1, e achamos que panspermia e’ potencialmente de grande magnitude para parecer mais possivel ocorrer em TRAPPIST-1 comparado com o caso de Terra-para-Marte.

As a consequence, we argue that the probability of abiogenesis is enhanced on the TRAPPIST-1 planets compared to the Solar system. By adopting models from theoretical ecology, we show that the number of species transferred and the number of life-bearing planets is also likely to be higher, because of the increased rates of immigration.
