ON THE EVOLUTION OF DUST MINERALOGY, FROM PROTOPLANETARY DISKS TO PLANETARY SYSTEMS [PDF]

open access: bronzeThe Astrophysical Journal, 2011
Mineralogical studies of silicate features emitted by dust grains in protoplanetary disks and Solar System bodies can shed light on the progress of planet formation. The significant fraction of crystalline material in comets, chondritic meteorites and interplanetary dust particles indicates a modification of the almost completely amorphous ISM dust ...

Planetary Materials (Reviews in Mineralogy, Volume 36) [PDF]

open access: bronzeEos, Transactions American Geophysical Union, 1999
Understanding the origin of planetary systems requires our comprehension of the materials from which the planets in our solar system formed. Exploring planetary formation draws from and contributes to a variety of scientific disciplines ranging from astrophysics to geology. One of the methods for understanding the composition and the geological history

Time-resolved Raman spectroscopy for in situ planetary mineralogy [PDF]

open access: bronzeApplied Optics, 2010
Planetary mineralogy can be revealed through a variety of remote sensing and in situ investigations that precede any plans for eventual sample return. We briefly review those techniques and focus on the capabilities for on-surface in situ examination of Mars, Venus, the Moon, asteroids, and other bodies.

From stellar to planetary composition: Galactic chemical evolution of Mg/Si mineralogical ratio [PDF]

open access: bronzeAstronomy & Astrophysics, 2015
The main goal of this work is to study element ratios that are important for the formation of planets of different masses. We study potential correlations between the existence of planetary companions and the relative elemental abundances of their host stars. We use a large sample of FGK-type dwarf stars for which precise Mg, Si, and Fe abundances have

Implications of Reactions Between SO2 and Basaltic Glasses for the Mineralogy of Planetary Crusts [PDF]

open access: hybridJournal of Geophysical Research: Planets, 2019
AbstractBasalts are ubiquitous in volcanic systems on several planetary bodies, including the Earth, Mars, Venus, and Jupiter's moon Io, and are commonly associated with sulfur dioxide (SO2) degassing. We present the results of an experimental study of reactions between SO2 and basaltic glasses. We examined Fe‐free basalt, and Fe‐bearing tholeiitic and

Mineralogical study of proto-planetary disks in FU Orionis stars [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2009
AbstractWe report on mid-infrared (8–13 μm) spectroscopic observations of eight FU Orionis type objects and discuss a qualitative initial mineralogical analysis.
