Chemical and isotopic anomalies in meteorites may be understandable in terms of the chemical fractionation routinely expected in the interstellar medium (ISM). Dust of distinct composition is idealized as being of three types: (1) thermal supernova condensates (SUNOCONS), (2) thermal condensation during other stellar mass-loss processes (STARDUST), and (3) nonthermal sticking processes in cold nebulae (NEBCONS). Great depletions in ISM of Ca Al Ti are due to SUNOCONS, although STARDUST is about… 
The role of presolar dust in the formation of the solar system
Isotopic studies have revealed several types of presolar material in chondritic meteorites (e.g., Ne-E, various components of O, Ti, Ca, Mg). In fact, examples of presolar material are found in all

Stars obtain their energy from nuclear-fusion reactions and these reactions can produce most elements and isotopes up to the neighbourhood of iron in the periodic table. Most more massive elements
Isotopic anomalies in meteorites
The classical picture of the pre-solar nebula is that of a hot, well-mixed cloud of chemically and isotopically uniform composition. Recent measurements have shown this conception to be erroneous,
Astrophysics with Presolar Stardust
▪ Abstract Meteorites and interplanetary dust particles contain presolar stardust grains: solid samples of stars that can be studied in the laboratory. The stellar origin of the grains is indicated

The origin of the ‘FUN’ anomalies and the high temperature inclusions in the allende meteorite
The discovery of isotopic anomalies in white inclusions of the meteorite Allende has led to fundamental questions concerning the origin of these anomalies and of the white inclusions themselves. An
Dust from Supernovae
Only a very small fraction of interstellar dust mass originates within the cooling expansions of supernova interiors; but those solids are exciting and important for other reasons. Thermally
Grain motions in the solar nebula
Isotopic analyses of meteorites suggest the possibility that some interaction between supernova ejecta and grains occurred in the solar nebula. In particular, the dynamics of grain motions in the

Condensation in supernova ejecta and isotopic anomalies in meteorites
Some of the observed isotopic anomalies in meteorites may be due to presolar grains that originated in supernova explosions. This hypothesis is investigated by performing chemical equilibrium
Nucleosynthesis during the Early History of the Solar System
Abundances in terrestrial and meteoritic matter indicate that the synthesis of D^2, Li^6, Li^7, Be^9, B^(10) and B^(11) and possibly C^(13) and N^(15) occurred during an intermediate stage in the
