Melting and differentiation of early-formed asteroids: The perspective from high precision oxygen isotope studies (2017, background): “This includes the fact that they are the host to CAIs, the oldest dated Solar System solids, (MacPherson, 2014), contain presolar grains (Zinner, 2014), display a wide range of isotopic anomalies (Meyer and Zinner, 2006; MacPherson and Boss, 2011) and include an organic component that probably…”
The Compositional Structure of the Asteroid Belt (2015, background): “The inclusions are the oldest known Solar System solids and, in some cases, formed by condensation from a hot gas, while others formed by melting and evaporation of pre-existing solids (MacPherson, 2014).”
The Effect of Jupiter's Formation on the Distribution of Refractory Elements and Inclusions in Meteorites (2017, background): “These have igneous textures consistent with the melting of pre-existing CAIs (MacPherson 2014).”
A Perspective from Extinct Radionuclides on a Young Stellar Object: The Sun and Its Accretion Disk (2011, background): “Most primitive meteorites contain refractory inclusions several tens of micrometers to a few centimeters in size that have ceramic-like mineralogy and chemistry (Christophe MichelLévy 1968, Grossman 1972, MacPherson 2005).”
