How Can Linguistics Help to Structure a Multidisciplinary Neo Domain such as Exobiology? [PDF]

open access: diamondBIO Web of Conferences, 2014
This chapter examines the contribution that corpus linguistics can make towards stabilising definitions within exobiology. By using the clues provided by natural language processing tools, linguists build an interpretation of contexts and try to show how

About Exobiology: The Case for Dwarf K Stars [PDF]

open access: green, 2016
One of the most fundamental topics of exobiology concerns the identification of stars with environments consistent with life. Although it is believed that most types of main-sequence stars might be able to support life, particularly extremophiles, special requirements appear to be necessary for the development and sustainability of advanced life forms.

A New Family of Planets ? "Ocean Planets" [PDF]

open access: yesIcarus 169:499-504,2004, 2003
A new family of planets is considered which is between rochy terrestrial planets and gaseous giant ones: "Ocean-Planets". We present the possible formation, composition and internal models of these putative planets, including that of their ocean, as well as their possible Exobiology interest.

Analytical Chemistry in Exobiology

open access: bronzeBiological Sciences in Space, 1988
Recent and scheduled chemical analysis in space missions are reviewed. Recent progress in analytical chemistry have made it possible to analyze chemical cpmposition of extraterrestrial samples in space. VEGA-1 and Giotto utilized mass spectrometers to analyze cometary dust particles. Phobos I and II are flying toward Mars and its moons.
