Presolar graphites are especially interesting in that
they encapsulate many internal grains during their growth,
preserving these higher temperature phases that condense in
the outflows of supernova (SN) and carbon stars. Coordinated
laboratory microanalysis of these phase assemblages, using
transmission electron microscopy and then secondary ion mass
spectrometry with high spatial resolution (NanoSIMS), can
reveal details about astrophysical processes that cannot be
obtained through astronomical observations.
