Since the discovery of the main composition of Titan's atmosphere, many laboratory experiments have been carried out to reproduce its chemical evolution, particularly the formation of organic haze particles found throughout this atmosphere. Some of t

In the present work, we focused on the possible isotopic fractionation of carbon during the processes involved in the formation of Titan’s tholins. We present the first results obtained on the 12C/13C isotopic ratios measured on Titan’s tholins s

The new Titan: an astrobiological perspective

Autor: Robert Sternberg, David Coscia, Marie-Claire Gazeau, François Raulin, Patrice Coll, Yves Bénilan, Claire Romanzin, Antoine Jolly, Eric Hébrard, M. J. Nguyen

Publikováno v: SPIE Proceedings.

Since the first Voyager data, Titan, the largest satellite of Saturn and only satellite in the solar system having a dense atmosphere, became one of the key planetary bodies for astrobiological studies, due to: i) its many analogies with planet Earth
