Origin Of Coronal High Temperature
center temperature gasification substances bian sphere coronal high
2015/6/2
In sun center, pressure least direction is ends of sun spin axis. Thus, sun center ultra-high temperature gasification substance jet out along sun's rotation axis, through photosphere, chromosphere, t...
Temperature-Pressure Profile of the hot Jupiter HD 189733b from HST Sodium Observations: Detection of Upper Atmospheric Heating
spectroscopic planetary systems individual HD 189733b
2012/2/23
We present transmission spectra of the hot Jupiter HD 189733b taken with the Space Telescope Imaging Spectrograph aboard HST. The spectra cover the wavelength range 5808-6380 Ang with a resolving powe...
On the effects of clouds and hazes in the atmospheres of hot Jupiters: semi-analytical temperature-pressure profiles
planets and satellites: atmospheres – radiative transfer
2011/9/29
Motivated by the work of Guillot (2010), we present a semi-analytical formalism for calculating the temperature-pressure profiles in hot Jovian atmospheres which includes the effects of clouds/hazes a...
Effective temperature for black holes
Black hole entropy Hawking radiation eff ective temperature
2011/10/14
The physical interpretation of black hole's quasinormal modes is fundamental for realizing unitary quantum gravity theory as black holes are considered theoretical laboratories for testing models of s...
Constraints from the CMB temperature and other common observational data-sets on variable dark energy density models
Cosmology Dark energy Thermodynamics
2011/10/13
The thermodynamic and dynamical properties of a variable dark energy model with density scaling as rho_x \propto (1+z)^m, z being the redshift, are discussed following the outline of Jetzer et al. Thi...
X-ray spectroscopy of Abell S1101 with Chandra, XMM-Newton and ROSAT: band-pass dependence of he temperature profile and soft excess emission
X-ray spectroscopy Chandra band-pass dependence temperature profile soft excess emission
2011/9/28
We present spatially-resolved spectroscopy of the galaxy cluster Abell S1101, also known as Sersic 159-03, with Chandra, XMM-Newton and ROSAT, and investigate the presence of soft X-ray excess emissio...
On the equivalent effective temperature of massive young star clusters: The case of NGC 595
equivalent effective temperature massive star clusters
2011/9/27
The softness parameter is based on the relative intensity of several optical emission lines emitted by the gas ionized by young massive star clusters and can be used to derive the equivalent effective...
The Signatures of Large-scale Temperature Fluctuations in the Lyman-alpha Forest
Large-scale Temperature Fluctuations the Lyman-alpha Forest
2011/1/11
It appears inevitable that reionization processes would have produced large-scale temperature fluctuations in the intergalactic medium. Using toy temperature models and detailed heating histories in c...
Coronal Temperature Diagnostic Capability of the Hinode/X-Ray Telescope Based on Self-Consistent Calibration
Corona Instrumentation and Data Management
2010/11/15
The X-Ray Telescope (XRT) onboard the Hinode satellite is an X-ray imager that observes the solar corona with unprecedentedly high angular resolution (consistent with its 1′′ pixel size). XRT has nine...
Foreground removal from WMAP 5yr temperature maps using an MLP neural network
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
One of the main obstacles for extracting the cosmic microwave background (CMB) signal from observations in the mm/sub-mm range is the foreground contamination by emission from Galactic component: main...
Evidence of Decay of Flux Ratio of Fe to Fe–Ni Line Features with Electron Temperature in Solar Flares
Sun flares corona—X-rays
2010/9/15
We report observational evidence of the decay of the flux ratio of Fe to Fe–Ni line features as a function of plasma electron temperature in solar flares in comparison to that theoretically predicted ...
The diffuse high-energy gamma-ray emission of the Milky Way arises from interactions of cosmic-rays (CRs) with interstellar gas and radiation field in the Galaxy. The neutral hydrogen (H I) gas compon...
CMB Temperature Polarization Correlation and Primordial Gravitational Waves：WMAP5
cosmic microwave background Primordial Gravitational Waves
2009/9/4
we continue our study of the CMB temperature polarization (TE) cross-correlation as a source of information about primordial gravitational waves (PGWs). In a previous paper, we considered two methods ...
