The Fate of Organic Phases in Porous Idps and Micrometeorites during Atmospheric Entry: a Pulse-heating Study
نویسنده
چکیده
Interplanetary dust particles (IDPs) and micrometeorites (MMs) are typically heated at temperatures higher than 500 C for few seconds during their atmospheric entry [1,2]. They have been extensively studied with several techniques for their carbon content and for the nature of their carbonaceous phases [3, 4, 5, 6]. Several kinds of organic molecules have been found in IDPs and MMs: polycyclic aromatic hydrocarbons (PAHs). [3], hydrocarbons and a carbonyl group (C=O) which was mainly associated with a ketone [4,5], and amino acids [7,8].

Primary Variations in Micrometeorites with Entry Velocity
Introduction: Micrometeorites are that fraction of the extraterrestrial dust flux that survives atmospheric entry to be recovered from the Earth’s surface. The majority of large micrometeorites (>50 μm), recovered from Antarctic ice, experience significant heating during atmospheric entry with the result that volatilebearing phases, such as clay minerals, have thermally decomposed. A significan...
متن کاملSimulation of Nitrogen and Noble Gases Release during Atmospheric Entry of Micrometeorites
Introduction: Micrometeorites represent the largest mass flux of extraterrestrial matter on Earth, and could have contributed significantly to the budget of volatile and biogenic elements at the Earth’s surface in the past [1]. Previous studies have shown that Antarctic micrometeorites (AMMs) have variable, and sometimes very high noble gas contents up to one order of magnitude higher than Orgu...
متن کاملVariations of oxygen isotopic compositions of silicate spherules collected from Antarctic blue ice
Introduction: Recent works suggest that unmelted, phillosilicate-bearing micrometeorites and hydrous interplanetary dust particles (IDPs) collected at stratosphere are related to hydrated carbonaceous chondrites [1], [2], which are supposed to be derived from C-, P-, D-, or T-type asteroids [3, 4]. Anhydrous IDPs are supposed to be cometary origin because of their high D/H ratios and characteri...

Introduction: Micrometeorites (MMs) are large (>25 µm) interplanetary dust particles that survive atmospheric entry to be recovered from the Earth's surface. Amongst those particles that escaped significant heating during atmospheric entry two groups have been identified [1]: (i) fine-grained MMs (fgMMs), which are similar to the fine-grained matrices of hy-drated carbonaceous chondrites (CCs),...

Introduction: NASA's Stardust spacecraft collected the first particles clearly identified a originating on a specific comet, 81P/Wild 2, and delivered them to Earth for examination. Prior to the Stardust collection it had been suggested that some chondritic porous in-terplanetary dust particles (CP IDPs) collected from the Earth's stratosphere were from comets, based on the degree of heating ex...
