Researchers Detect Exoplanet Glowing Water Atmosphere
2017/9/1
Scientists have found compelling evidence for a stratosphere on an enormous planet outside our solar system. The planet’s stratosphere—a layer of atmosphere where temperature increases with higher alt...
Super-Earth's atmosphere comes into view（图）
Super-Earth's atmosphere astronomers the first extra-solar planet
2011/1/21
A team of astronomers has made the first direct measurement of the atmosphere of an exoplanetary "super-Earth". The findings suggest that the exoplanet named GJ 1214b has either an atmosphere swarming...
Propagation in the atmosphere of ultrahigh-energy charmed hadrons
Propagation the atmosphere ultrahigh-energy charmed hadrons
2011/1/13
Charmed mesons may be produced when a primary cosmic ray or the leading hadron in an air shower collide with an atmospheric nucleon. At energies \ge 10^8 GeV their decay length becomes larger than 10 ...
New limb-darkening coefficients and synthetic photometry for model-atmosphere grids at Galactic, LMC, and SMC abundances
New limb-darkening coefficients synthetic photometry for model-atmosphere grids SMC abundances
2010/11/15
New grids of Atlas9 models have been calculated using revised convection parame-ters and updated opacity-distribution functions, for chemical compositions intended to be representative of solar, [M/H]...
Possible thermochemical disequilibrium in the atmosphere of the exoplanet GJ 436b
Possible thermochemical disequilibrium the exoplanet GJ 436b
2011/1/10
The nearby extrasolar planet GJ 436b--which has been labelled as a 'hot Neptune'--reveals itself by the dimming of light as it crosses in front of and behind its parent star as seen from Earth. Respec...
The Laboratory Complex for the Calibration of Photometers Using the Optical Method for Determination of the Water Vapor Content in the Earth Atmosphere
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
We describe the laboratory complex for the calibration of photometers that are used in weather service to measure the water vapor content in the Earth atmosphere.
Chemical abundances in metal-poor giants: limitations imposed by the use of classical 1D stellar atmosphere models
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
In this work we have used 3D hydrodynamical (CO5BOLD) and 1D hydrostatic (LHD) stellar atmosphere models to study the importance of convection and horizontal temperature inhomogeneities in stellar abu...
Observing and modeling the dynamic atmosphere of the low mass-loss C-star R Sculptoris at high angular resolution
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
We study the circumstellar environment of the carbon-rich star R Scl using the near- and mid-infrared high spatial resolution observations from the ESO-VLTI instruments VINCI and MIDI. These observati...
Transient Perturbations and their Effects in the Heliosphere, the Geomagnetosphere, and the Earth’s Atmosphere: Space Weather Perspective
Space weather geomagnetic storm cosmic ray Forbush decrease interplanetary shock coronal mass ejection
2010/9/16
We discuss the effects of certain dynamic features of space environment in the heliosphere, the geo-magnetosphere, and the earth’s atmosphere. In particular, transient perturbations in solar wind plas...
Physics of the Sun’s Hot Atmosphere
Solar atmosphere X-ray EUV emission coronal heating solar wind
2010/9/16
This article briefly overviews the physics of the Sun’s hot atmosphere,using observations from recent solar spacecrafts: Yohkoh, SOHO,TRACE and RHESSI.
Astronomers in Canada and Germany have made the first direct measurement of the atmospheric spectrum of a planet outside our solar system. Using the European Southern Observatory (ESO) Very Large Tele...

Prediction of the structure of the martian upper atmosphere for the Mars Reconnaissance Orbiter (MRO) mission
Mars Reconnaissance Orbiter mapping orbit General Circulation Model predictions
2009/6/1
The Mars Reconnaissance Orbiter (MRO) spacecraft will undergo aerobraking from April through September 2006 in order to achieve the desired mapping orbit. This aerobraking process requires knowledge o...
MHD simulation of electric currents in the solar atmosphere caused by photospheric plasma motion
Bright Points electric currents solar atmosphere
2009/5/27
Photospheric plasma motion may cause the build-up of electric currents in the solar atmosphere. These electric currents may then dissipate and heat the corona, cause EUV and X-ray Bright Points (BPs)...
