Context. Aluminium oxide (alumina; Al 2 O 3) is a promising candidate as a primary dust
condensate in the atmospheres of oxygen-rich evolved stars. Therefore, alumina …

Minerals preserve records of the physical, chemical, and biological histories of their origins
and subsequent alteration, and thus provide a vivid narrative of the evolution of Earth and …

Abstract NanoSIMS C-, N-, and O-isotopic mapping of matrix in CO3. 0 chondrite Dominion
Range (DOM) 08006 revealed it to have in its matrix the highest abundance of presolar O …

We report a NanoSIMS search for presolar grains in the CM chondrites Asuka (A) 12169 and
A12236. We found 90 presolar O‐rich grains and 25 SiC grains in A12169, giving matrix …

Context. Dust grains forming in the extended atmospheres of AGB stars are critical for the
heavy mass loss of these cool luminous giants, as they provide radiative acceleration for the …

Abstract Primitive Solar System materials host small amounts of refractory dust grains
predating the formation of the Sun and its planetary system. These 'presolar'grains …

Aims. We study the growth of dust in oxygen-rich stellar outflows in order to find out to which
extent dust growth models can quantitatively reconcile with the quantities and nature of dust …

We report the structural and chemical analyses of six presolar silicate grains identified in situ
in the CO3. 0 carbonaceous chondrite Dominion Range (DOM) 08006. Two of the grains …

Aluminum and silicon are present in large quantities in the interstellar medium, making the
triatomic species consisting of both elements intriguing with regard to the foundations of …

A coordinated TEM and NanoSIMS isotopic imaging study of microtome sections of three
anhydrous interplanetary dust particles (IDPs) revealed a diverse collection of primitive …
