Meteorites and the early solar system II

  title={Meteorites and the early solar system II},
  author={Dante S. Lauretta and Harry Y. McSween},
They range in size from microscopic particles to masses of many tons. The geologic diversity of asteroids and other rocky bodies of the solar system are displayed in the enormous variety of textures and mineralogies observed in meteorites. The composition, chemistry, and mineralogy of primitive meteorites collectively provide evidence for a wide variety of chemical and physical processes. This book synthesizes our current understanding of the early solar system, summarizing information about… 

Meteorites: messengers from the early solar system.

The present high find rate likely represents a unique short-term event, asking for a careful management of this scarce scientific resource.

Mineralogical Evolution of Meteorites

The approximately 250 mineral species found in meteorites record the earliest stages of the birth of our solar system. Refractory minerals that formed during the violent deaths of other stars and

Organic Chemistry of Carbonaceous Meteorites

The early Solar System contained a wide range of abiotic organic compounds. As the Solar System evolved, these organic molecules were incorporated into planetesimals and eventually planetary bodies,

Meteorites, Asteroids and the Age and Origin of the Solar System

In the previous chapter, we discussed sporadic meteors and meteor showers and indicated that some of the former and most of the latter likely originate from comets. Here we discuss the source of the

A Cosmochemical View of the Solar System

Cosmochemistry is the study of extraterrestrial materials aimed at understanding the nature of Solar System bodies, including the planets, their natural satellites, and small bodies. An important

Nucleosynthetic isotope anomalies in meteorites—clues for solar system origin

The solar system was previously thought to have evolved from a hot and well‐mixed solar nebula, until the discovery of nucleosynthetic isotope anomalies in meteorites flew in the face of this popular

The study of the origin and evolution of the Solar System is based on laboratory analysis of meteorites and other extraterrestrial materials, and on astronomical observations of star-forming regions

Abstract As observational facilities improve, providing new insights into the chemistry occurring in protoplanetary disks, it is important to develop more complete pictures of the processes that

Meteorites from the Outer Solar System

We investigate the possibility that a small fraction of meteorites originate from the outer solar system, i.e., from the Kuiper belt, the Oort cloud, or from the Jupiter-family comet reservoir.



Meteorites and the early solar system

The present work discusses topics in the source regions for meteorites, their secondary processing, irradiation effects on meteorites, solar system chronology, the early solar system, the chemistry

Stardust silicates from primitive meteorites

In situ discovery of presolar silicate grains 0.1–1 µm in size in the matrices of two primitive carbonaceous chondrites, which have solar silicon isotopic compositions within analytical uncertainties, suggesting an origin in an oxygen-rich red giant or an asymptotic giant branch star.

Evidence for molecular cloud material in meteorites and interplanetary dust

Some primitive meteorites and interplanetary dust particles (IDPs) exhibit large excesses in deuterium (D) and/or 15N relative to terrestrial values. These anomalies likely represent the partial

Discovery of Ancient Silicate Stardust in a Meteorite

One grain is enriched in 26Mg, which is attributed to the radioactive decay of 26Al and provides information about mixing processes in the parent star and opens new means for studying stellar processes and conditions in various solar system environments.

Protostellar collapse, dust grains and solar system formation

Attempts to understand the origin of the solar system come from two perspectives. The first is that of the insider looking out; the system components beyond the earth are examined in detail, their

Dust metamorphosis in the galaxy

SummaryCosmic dust grains play an important role for the thermal, dynamical, and chemical structure of the interstellar medium. This is especially true for the star formation process and the late

Interstellar diamonds in meteorites

Primitive meteorites contain up to 400 p.p.m. of a very fine-grained type of carbon, noncommittally called Cδ1. It apparently conies from outside the Solar System, as it carries isotopically

Identification of molecular-cloud material in interplanetary dust particles

It is shown that H and N isotopic anomalies among fragile ‘cluster’ IDPs are far larger, more common, and less equilibrated than those previously observed in other IDPs or meteorites, suggesting that molecular-cloud material has survived intact.

Samples of Stars Beyond the Solar System: Silicate Grains in Interplanetary Dust

Six circumstellar silicate grains within interplanetary dust particles (IDPs) are identified, and one of the grains is forsterite, and two are amorphous silicate “GEMS” (glass with embedded metal and sulfides), which is consistent with astronomical identifications of crystalline and amorphously silicates in the outflows of evolved stars.
