Characterization of high-resolution aerosol mass spectra of primary organic aerosol emissions from Chinese cooking and biomass burning
high-resolution aerosol mass spectra primary organic aerosol Chinese cooking biomass burning
2010/12/28
Aerosol mass spectrometry has proved to be a powerful tool to measure submicron particulate composition with high time resolution. Factor analysis of mass spectra (MS) collected worldwide by aerosol m...
High-energy astrophysics is a relatively young scientific field, made possible by space-borne telescopes. During the half-century history of x-ray astronomy, the sensitivity of focusing x-ray telescop...
High-resolution simulations of planetesimal formation in turbulent protoplanetary discs
High-resolution simulations turbulent protoplanetary discs
2011/1/10
We present high-resolution computer simulations of dust dynamics and planetesimal formation in turbulence generated by the magnetorotational instability. We show that the turbulent viscosity associate...
Coarse, intermediate and high resolution numerical simulations of the transition of a tropical wave critical layer to a tropical storm
resolution numerical the transition of a tropical wave critical layer a tropical storm
2010/11/30
Recent work has hypothesized that tropical cyclones in the deep Atlantic and eastern Pacific basins develop from within the cyclonic Kelvin cat's eye of a tropical easterly wave critical layer located...
Phase stability and structural temperature dependence in sodium niobate: A high resolution powder neutron diffraction study
Phase stability structural temperature dependence high resolution powder neutron diffraction
2010/11/24
We report investigation of structural phase transitions in technologically important material sodium niobate as a function of temperature on heating over 300-1075 K. Our high resolution powder neutron...
High Resolution HDS/SUBARU chemical abundances of the young stellar cluster Palomar 1

2010/11/9
Context. Palomar 1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered in the Milky Way (MW),...
High resolution spectroscopy of methyltrioxorhenium: towards the observation of parity violation in chiral molecules
High resolution spectroscopy methyltrioxorhenium chiral molecules
2010/11/12
Originating from the weak interaction, parity violation in chiral molecules has been considered as a possible origin of the biohomochirality. It was predicted in 1974 but has never been observed so f...
A High-Resolution Survey of HI Absorption toward the Central 200 pc of the Galactic Center
High-Resolution Survey Galactic Center
2010/11/10
We present an HI absorption survey of the central 250 pc of the Galaxy. Very Large Array (VLA) observations were made at 21 cm in the DnC and CnB con gurations and have a resolution of 15"(0.6 pc at ...
Dissecting the Moth: Discovery of an off-centered ring in the HD 61005 debris disk with high-resolution imaging
circumstellar matter — planetary systems protoplanetary disks — Techniques
2010/11/15
The debris disk known as “The Moth” is named after its unusually asymmetric surface brightness distribution. It is located around the ∼90Myr old G8V star HD 61005 at 34.5 pc and has previously b...
