Prediction of equilibrium Li isotope fractionation between minerals and aqueous solutions at high P and T: an efficient ab initio approach
equilibrium isotope fractionation aqueous solutions efficient initio approach
2011/10/14
The mass-dependent equilibrium stable isotope fractionation between different materials is an important geochemical process. Here we present an efficient method to compute the isotope fractionation be...
Propagation of Highly Efficient Star Formation in NGC 7000
Star: formation - ISM: HII region - ISM: individual (SFR) - line (NH3)
2011/10/12
We surveyed the (1,1), (2,2), and (3,3) lines of NH3 and the H2O maser toward the molecular cloud L935 in the extended HII region NGC 7000 with an angular resolution of 1.6' using the Kashima 34-m tel...
Investigations of mass segregation are of vital interest for the understanding of the formation and dynamical evolution of stellar systems on a wide range of spatial scales. Our method is based on the...
Fuel Efficient Galaxies: Sustaining Star Formation with Stellar Mass Loss
cosmology theory – galaxies evolution – galaxies formation – stars formation – methods
2010/11/11
We examine the importance of secular stellar mass loss for fueling ongoing star formation in disk galaxies during the late stages of their evolution. For a galaxy of a given stellar mass, we calculate...
Libpsht - algorithms for efficient spherical harmonic transforms
Instrumentation and Methods for Astrophysics (astro-ph.IM) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
Libpsht (or "library for Performant Spherical Harmonic Transforms") is a collection of algorithms for efficient conversion between spatial-domain and spectral-domain representations of data defined on...
Cosmic-ray current driven turbulence in shocks with efficient particle acceleration: the oblique, long-wavelength mode instability
High Energy Astrophysical Phenomena (astro-ph.HE) Plasma Physics (physics.plasm-ph)
2010/12/23
In order for diffusive shock acceleration (DSA) to accelerate particles to high energies, the energetic particles must be able to interact with magnetic turbulence over a broad wavelength range.
Type I Migration in Radiatively Efficient Discs
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
We study Type I migration of a planet in a radiatively efficient disk using global two dimensional hydrodynamic simulations. The large positive corotation torque is exerted on a planet by an adiabatic...
