Recent isotopic analysis of meteorites and interplanetary dust has identified solid-state materials of pre-solar origin. We can now trace the origin of these inorganic grains to the circumstellar envelopes of evolved stars. Moreover, organic (aromatic and aliphatic) compounds have been detected in proto-planetary nebulae and planetary nebulae, which are the descendants of carbon stars. This implies that molecular synthesis is actively happening in the circumstellar environment on timescales as… 

Title Organic Compounds in Circumstellar and Interstellar Environments

Recent research has discovered that complex organic matter is prevalent throughout the Universe. In the Solar System, it is found in meteorites, comets, interplanetary dust particles, and planetary

Amorphous organic solids as a component of interstellar dust

The discovery of rapid synthesis of complex organic solids in the late stages of stellar evolution has led to a new realization that carbonaceous compounds can be a major significant component of

Cosmic carbon chemistry: from the interstellar medium to the early Earth.

The connection between presolar and solar system material is investigated based on observations of interstellar dust and gas, cometary volatiles, simulation experiments, and the analysis of extraterrestrial matter.

Abstract Through the techniques of millimeter-wave and infrared spectroscopy, over 60 species of gas-phase molecules and a variety of inorganic and organic solids have been detected in the short

Chemical enrichment of galaxies as the result of organic synthesis in evolved stars

Abstract Infrared spectroscopic observations have shown that complex organics with mixed aromatic-aliphatic structures are synthesized in large quantities during the late stages of stellar evolution.

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.

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.

The origin of circumstellar silicon carbide grains found in meteorites

— Condensation calculations for C-rich circumstellar envelopes are used to model the condensation sequence of C, TiC, and SiC, and trace-element patterns observed in circumstellar SiC grains. Some


▪ Abstract Primitive meteorites contain grains of stardust that originated from stellar outflows and supernova ejecta prior to the formation of the Solar System. The study of these grains in the

Evidence for interstellar SiC in the Murray carbonaceous meteorite

Silicon carbide has been observed in the interstellar medium and in circumstellar shells. Although it might be expected to occur in primitive meteorites that contain other kinds of pre-solar

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.

A far-infrared emission feature in carbon-rich stars and planetary nebulae

The 16-30 micron spectra of several carbon stars and the planetary nebulae IC 418 and NGC 6572 have been obtained using the NASA C-141 Kuiper Airborne Observatory. A newly observed emission feature

On the Origin of Infrared Plateau Features in Proto-Planetary Nebulae*

The emission profiles of the 8 and 12 μm plateau features are derived from the Infrared Space Observatory spectra of proto-planetary nebulae. We suggest that these plateau features are primarily the

Titanium carbide nanocrystals in circumstellar environments.

It is concluded that titanium carbide forms during a short (approximately 100 years) phase of catastrophic mass loss in dying, low-mass stars.
