Preface: Evolution of the solar system: New advances in cosmochemistry and planetary chemistry
cosmochemistry planetary chemistry
2017/4/10
The understanding of evolution of solar system has been
recently entered a phase of major change with the results
of new astronomical observation, several primitive extraterrestrial
samples includi...
The Chemistry of the Early Universe
stars: formation – galaxies: formation – cosmology: theory
2011/10/10
The chemistry of the early Universe is a fascinating field of study. Even in the absence of any elements heavier than lithium, a surprising degree of chemical complexity proves to be possible, giving ...
Chemistry in a gravitationally unstable protoplanetary disc
stars: pre-main-sequence, stars: circumstellar matter, protoplanetary discs, astrochemistry
2011/10/9
Until now, axisymmetric, alpha-disc models have been adopted for calculations of the chemical composition of protoplanetary discs. While this approach is reasonable for many discs, it is not appropria...
Distance determination for RAVE stars using stellar models III: The nature of the RAVE survey and Milky Way chemistry
Stars: distances, Stars: fundamental parameters, Galaxy: abundances, Galaxy: disk, Galaxy: stellar content, Galaxy: structure
2011/9/29
We apply the method of Burnett & Binney (2010) for the determination of stellar distances and parameters to the internal catalogue of the Radial Velocity Experiment (Steinmetz et al. 2006). Subsamples...
The Potential Importance of Non-Local, Deep Transport on the Energetics, Momentum, Chemistry, and Aerosol Distributions in the Atmospheres of Earth, Mars and Titan
Non-Local Deep Transport the Energetics
2011/1/11
A review of non-local, deep transport mechanisms in the atmosphere of Earth provides a good foundation for examining whether similar mechanisms are operating in the atmospheres of Mars and Titan. On E...
Ice chemistry in massive Young Stellar Objects: the role of metallicity
astrochemistry – circumstellar matter – galaxies individual (LMC, SMC) –Magellanic Clouds – stars formation – stars: protostars
2010/11/15
We present the comparison of the three most important ice constituents (water, CO and CO2)
in the envelopes of massive Young Stellar Objects (YSOs), in environments of differentmetallicities:the Gala...
Chemistry in Evaporating Ices: Unexplored Territory
astrochemistry – ISM molecules ISM clouds
2010/11/15
We suggest that three–body chemistry may occur in warm high density gas evaporating in transient co–desorption events on interstellar ices. Using a highly idealised computational model we explore the ...
The chemistry of interstellar HnO+ beyond the Galaxy
molecules – radio lines galaxies – galaxies active – galaxies AGN – galaxies starburst – galaxies evolution
2010/11/10
The astrochemistry of the HnO+ (n=1..3) ions is important as the main gas-phase formation route for water, and as tracer of the interstellar ionization rate by cosmic rays and other processes. While i...
Chemistry of a protoplanetary disk with grain settling and Lyman alpha radiation
astrochemistry circumstellar matter ISM abundances ISM: molecules planetary systems
2010/11/10
We present results from a model of the chemical evolution of protoplanetary disks. In our models we directly calculate the changing propagation and penetration of a high energy radiation field with Ly...
