Analytic solutions to the accretion of a rotating finite cloud towards a central object - II. Schwarzschild spacetime
accretion, accretion discs, black hole physics, hydrodynamics, relativistic processes
2011/9/30
We construct a general relativistic model for the accretion flow of a rotating finite cloud of non-interacting particles infalling onto a Schwarzschild black hole. The streamlines start at a spherical...
Highly absorbed X-ray binaries in the Small Magellanic Cloud
galaxies: Small Magellanic Cloud – stars: emission–line, Be – X-rays: binaries
2011/9/29
Many of the high mass X-ray binaries (HMXRBs) discovered in recent years in our Galaxy are characterized by a high absorption, most likely intrinsic to the system, which hampers their detection at the...
The State of the Gas and the Relation Between Gas and Star Formation at Low Metallicity: the Small Magellanic Cloud
State Relation Between Gas Star Formation Metallicity: Magellanic Cloud
2011/9/30
We compare atomic gas, molecular gas, and the recent star formation rate (SFR) inferred from H-alpha in the Small Magellanic Cloud (SMC). By using infrared dust emission and local dust-to-gas ratios, ...
Cloud is an important factor affect the quality of optical remote sensing image. How to automatically detect the cloud cover of an image, reduce of useless data transmission, make great significance o...
A global survey of aerosol-liquid water cloud overlap based on four years of CALIPSO-CALIOP data
aerosol-liquid water cloud CALIPSO-CALIOP data
2011/2/25
Simulating the radiative impacts of aerosols located above liquid water clouds presents a significant challenge. In particular, absorbing aerosols, such as smoke, may have significant impact in such s...
Influence of convection and aerosol pollution on ice cloud particle effective radius
convection and aerosol pollution ice cloud particle radius
2011/1/20
Satellite observations show that ice cloud effective radius (re) increases with ice water content (IWC) but decreases with aerosol optical thickness (AOT). Using least-squares fitting to the observed ...
Global analysis of cloud field coverage and radiative properties, using morphological methods and MODIS observations
cloud field coverage radiative properties morphological methods MODIS observations
2011/1/19
The recently recognized continuous transition zone between detectable clouds and cloud-free atmosphere ("the twilight zone") is affected by undetectable clouds and humidified aerosol. In this study, w...
On average, airborne aerosol particles cool the Earth's surface directly by absorbing and scattering sunlight and indirectly by influencing cloud reflectivity, life time, thickness or extent. Here we ...
Laboratory investigations of the impact of mineral dust aerosol on cold cloud formation
mineral dust aerosol cold cloud formation Laboratory
2010/12/28
Dust particles represent a dominant source of particulate matter (by mass) to the atmosphere, and their emission from some source regions has been shown to be transported on regional and hemispherical...
Cloud thermodynamic phase inferred from merged POLDER and MODIS data
Cloud thermodynamic phase merged POLDER and MODIS data
2010/12/28
The global spatial and diurnal distribution of cloud properties is a key issue for understanding the hydrological cycle, and critical for advancing efforts to improve numerical weather models and gene...
Stratocumulus cloud thickening beneath layers of absorbing smoke aerosol
Stratocumulus cloud smoke aerosol
2010/12/28
Marine stratocumulus cloud properties, and the free-tropospheric environment above them, are examined in NASA A-Train satellite data for cases where smoke from seasonal burning of the West African sav...
Chemical Variation in Molecular Cloud Cores in the Orion A Cloud
Chemical Variation Molecular Cloud Cores the Orion A Cloud
2011/1/10
We have observed molecular cloud cores in the Orion A giant molecular cloud (GMC) in CCS, HC3N, DNC, and HN13C to study their chemical characteristics. We have detected CCS in the Orion A GMC for the ...
On the interaction of a thin, supersonic shell with a molecular cloud
supersonic shell with molecular cloud
2011/1/10
Molecular clouds (MCs) are stellar nurseries, however, formation of stars within MCs depends on the ambient physical conditions. MCs, over a free-fall time are exposed to numerous dynamical phenomena,...
The XMM-Newton survey of the Small Magellanic Cloud: A new X-ray view of the symbiotic binary SMC3
The XMM-Newton survey the Small Magellanic Cloud
2011/1/11
The XMM-Newton survey of the Small Magellanic Cloud (SMC) was performed to study the population of X-ray sources in this neighbouring galaxy. During one of the observations, the symbiotic binary SMC3 ...
The XMM-Newton survey of the Small Magellanic Cloud: Discovery of the 11.866 s Be/X-ray binary pulsar XMMUJ004814.0-732204 (SXP11.87)
The XMM-Newton survey the Small Magellanic Cloud
2011/1/11
One of the goals of the XMM-Newton survey of the Small Magellanic Cloud is the study of the Be/X-ray binary population. During one of our first survey observations a bright new transient - XMMUJ004814...
