Africa-Press – S\u00e3o Tom\u00e9 e Pr\u00edncipe. <\/strong><\/span>Une nouvelle \u00e9tude d\u2019une vieille m\u00e9t\u00e9orite contredit la pens\u00e9e actuelle sur la fa\u00e7on dont les plan\u00e8tes rocheuses comme la Terre et Mars acqui\u00e8rent des \u00e9l\u00e9ments volatils tels que l\u2019hydrog\u00e8ne, le carbone, l\u2019oxyg\u00e8ne, l\u2019azote et les gaz nobles lors de leur formation. L\u2019ouvrage est publi\u00e9 le 16 juin dans La science.<\/p>\n

Une hypoth\u00e8se de base sur la formation des plan\u00e8tes est que les plan\u00e8tes collectent d\u2019abord ces volatiles de la n\u00e9buleuse autour d\u2019une jeune \u00e9toile, a d\u00e9clar\u00e9 Sandrine P\u00e9ron, une chercheuse postdoctorale travaillant avec le professeur Sujoy Mukhopadhyay au D\u00e9partement des sciences de la Terre et des plan\u00e8tes de l\u2019Universit\u00e9 de Californie \u00e0 Davis.<\/p>\n

Parce que la plan\u00e8te est une boule de roche en fusion \u00e0 ce stade, ces \u00e9l\u00e9ments se dissolvent initialement dans l\u2019oc\u00e9an de magma, puis se d\u00e9gazent dans l\u2019atmosph\u00e8re. Plus tard, les m\u00e9t\u00e9orites chondritiques qui s\u2019\u00e9crasent sur la jeune plan\u00e8te livrent des mat\u00e9riaux plus volatils.<\/p>\n

Les scientifiques s\u2019attendent donc \u00e0 ce que les \u00e9l\u00e9ments volatils \u00e0 l\u2019int\u00e9rieur de la plan\u00e8te refl\u00e8tent la composition de la n\u00e9buleuse solaire, ou un m\u00e9lange de volatils solaires et m\u00e9t\u00e9oritiques, tandis que les volatils dans l\u2019atmosph\u00e8re proviendraient principalement des m\u00e9t\u00e9orites. Ces deux sources \u2013 solaire vs chondritique \u2013 peuvent \u00eatre distingu\u00e9es par les rapports des isotopes des gaz nobles, en particulier du krypton.<\/p>\n

Mars pr\u00e9sente un int\u00e9r\u00eat particulier car il s\u2019est form\u00e9 relativement rapidement \u2013 se solidifiant environ 4 millions d\u2019ann\u00e9es apr\u00e8s la naissance du syst\u00e8me solaire, tandis que la Terre a mis 50 \u00e0 100 millions d\u2019ann\u00e9es \u00e0 se former.<\/p>\n

\u00ab Nous pouvons reconstituer l\u2019histoire de la livraison volatile au cours des premiers millions d\u2019ann\u00e9es du syst\u00e8me solaire \u00bb, a d\u00e9clar\u00e9 P\u00e9ron.<\/p>\n

M\u00e9t\u00e9orite de l\u2019int\u00e9rieur de Mars<\/p>\n

Certaines m\u00e9t\u00e9orites qui tombent sur Terre proviennent de Mars. La plupart proviennent de roches de surface qui ont \u00e9t\u00e9 expos\u00e9es \u00e0 l\u2019atmosph\u00e8re de Mars. La m\u00e9t\u00e9orite de Chassigny, tomb\u00e9e sur Terre dans le nord-est de la France en 1815, est rare et inhabituelle car on pense qu\u2019elle repr\u00e9sente l\u2019int\u00e9rieur de la plan\u00e8te.<\/p>\n

En effectuant des mesures extr\u00eamement minutieuses de quantit\u00e9s infimes d\u2019isotopes de krypton dans des \u00e9chantillons de la m\u00e9t\u00e9orite \u00e0 l\u2019aide d\u2019une nouvelle m\u00e9thode mise en place au UC Davis Noble Gas Laboratory, les chercheurs ont pu d\u00e9duire l\u2019origine des \u00e9l\u00e9ments dans la roche.<\/p>\n

\u00ab En raison de leur faible abondance, les isotopes du krypton sont difficiles \u00e0 mesurer \u00bb, a d\u00e9clar\u00e9 P\u00e9ron.<\/p>\n

\u00c9tonnamment, les isotopes du krypton dans la m\u00e9t\u00e9orite correspondent \u00e0 ceux des m\u00e9t\u00e9orites chondritiques, et non \u00e0 la n\u00e9buleuse solaire. Cela signifie que les m\u00e9t\u00e9orites livraient des \u00e9l\u00e9ments volatils \u00e0 la plan\u00e8te en formation bien plus t\u00f4t qu\u2019on ne le pensait auparavant, et en pr\u00e9sence de la n\u00e9buleuse, inversant la pens\u00e9e conventionnelle.<\/p>\n

\u00ab La composition int\u00e9rieure martienne du krypton est presque purement chondritique, mais l\u2019atmosph\u00e8re est solaire \u00bb, a d\u00e9clar\u00e9 P\u00e9ron. \u00ab C\u2019est tr\u00e8s distinct. \u00bb<\/p>\n

Les r\u00e9sultats montrent que l\u2019atmosph\u00e8re de Mars ne peut pas s\u2019\u00eatre form\u00e9e uniquement par d\u00e9gazage du manteau, car cela lui aurait donn\u00e9 une composition chondritique. La plan\u00e8te doit avoir acquis l\u2019atmosph\u00e8re de la n\u00e9buleuse solaire, apr\u00e8s le refroidissement de l\u2019oc\u00e9an magmatique, pour emp\u00eacher un m\u00e9lange substantiel entre les gaz chondritiques int\u00e9rieurs et les gaz solaires atmosph\u00e9riques.<\/p>\n

Les nouveaux r\u00e9sultats sugg\u00e8rent que la croissance de Mars s\u2019est achev\u00e9e avant que la n\u00e9buleuse solaire ne soit dissip\u00e9e par le rayonnement du Soleil. Mais l\u2019irradiation aurait \u00e9galement d\u00fb souffler sur l\u2019atmosph\u00e8re n\u00e9bulaire de Mars, ce qui sugg\u00e8re que le krypton atmosph\u00e9rique a d\u00fb \u00eatre pr\u00e9serv\u00e9 d\u2019une mani\u00e8re ou d\u2019une autre, \u00e9ventuellement pi\u00e9g\u00e9 sous terre ou dans des calottes glaciaires polaires.<\/p>\n

\u00ab Cependant, cela n\u00e9cessiterait que Mars ait \u00e9t\u00e9 froide imm\u00e9diatement apr\u00e8s son accr\u00e9tion \u00bb, a d\u00e9clar\u00e9 Mukhopadhyay. \u00ab Bien que notre \u00e9tude indique clairement les gaz chondritiques \u00e0 l\u2019int\u00e9rieur de Mars, elle soul\u00e8ve \u00e9galement des questions int\u00e9ressantes sur l\u2019origine et la composition de l\u2019atmosph\u00e8re primitive de Mars. \u00bb<\/p>\n
