Hot-Dust-Poor Quasars in Mid-Infrared and Optically Selected Samples
galaxies evolution quasars general surveys
2010/11/9
We show that the Hot-Dust-Poor (HDP) quasars found in the X-ray selected XMM-COSMOS type
1 AGN sample are just as common in two samples selected at optical/infrared wavelengthes: the
Richards et al....
Intermediate distance correlators in hot Yang-Mills theory
Intermediate distance correlators hot Yang-Mills theory
2011/1/14
Lattice measurements of spatial correlation functions of the operators FF and F ˜ F in thermal
SU(3) gauge theory have revealed a clear difference between the two channels at“intermediate”distan...
CS Lines Profiles in Hot Cores
astrochemistry—line profiles—methods numerical—stars formation—ISM
2010/11/11
We present a theoretical study of CS line profiles in archetypal hot cores. We provide estimates of line fluxes from the CS(1-0) to the CS(15-14) transitions and present the temporal variation of thes...
Revisiting with Chandra the Scaling Relations of the X-ray Emission Components (Binaries, Nuclei and Hot Gas) of Early Type Galaxies
galaxies elliptical and lenticular – X-rays galaxies
2010/11/15
We have selected a sample of 30 normal (non-cD) early type galaxies, for all of which optical spectroscopy is available, and which have been observed with Chandra to a depth such to insure the detecti...
Retrograde Hot Jupiters from Secular Planet-Planet Interactions
Retrograde Hot Jupiters Secular Planet-Planet Interactions
2010/11/15
The search for extra-solar planets has led to the surprising discovery of many Jupiter-like planets in very close proximity to their host star1, the so-called “hot Jupiters.”
Standing Slow-Mode Waves in Hot Coronal Loops: Observations, Modeling, and Coronal Seismology
Solar activity Solar corona Coronal Seismology Coronal loops
2010/11/15
Strongly damped Doppler shift oscillations are observed frequently associated with flarelike events in hot coronal loops. In this paper, a review of the observed properties and the theoretical modelin...
High growth rate 4H-SiC epitaxial growth using dichlorosilane in a hot-wall CVD reactor
High growth rate 4H-SiC epitaxial growth hot-wall CVD reactor
2010/11/18
Thick, high quality 4H-SiC epilayers have been grown in a vertical hot-wall chemical
vapor deposition system at a high growth rate on (0001) 80 off-axis substrates. We
discuss the use of dichlorosil...
We analyse the stellar and hot gas content of 18 nearby, low-mass galaxy clusters, detected in
redshift space and selected to have a dynamical mass 3 × 1014 < M/M⊙ < 6 × 1014 (h =0.7), as measured fr...
Jets, Mach cone, hot spots, ridges, harmonic flow, dihadron and $\gamma$-hadron correlation in high-energy heavy-ion collisions
Jets Mach cone hot spots ridges harmonic flow dihadron $\gamma$-hadron correlation high-energy heavy-ion collisions
2011/1/7
Within the AMPT Monte Carlo model, hot spots in the initial transverse parton density are
shown to lead to harmonic flows which all contribute to dihadron azimuthal correlation.
On the Inference of Thermal Inversions in Hot Jupiter Atmospheres
Thermal Inversions Hot Jupiter Atmospheres
2011/1/10
Several studies in the recent past have inferred the existence of thermal inversions in some transiting hot Jupiter atmospheres. Given the limited data available, the inference of a thermal inversion ...
A Population of Very-Hot Super-Earths in Multiple-Planet Systems Should be Uncovered by Kepler
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
We simulate a Kepler-like observation of a theoretical exoplanet population and we show that the observed orbital period distribution of the Kepler giant planet candidates is best matched by an averag...
Observational asteroseismology of hot subdwarf stars
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
Hot subdwarf stars are particularly challenging for asteroseismology due to their rapid pulsation periods, intrinsic faintness and relative rarity both in the field and in clusters. These features hav...
Turbulence and magnetic spots at the surface of hot massive stars
Solar and Stellar Astrophysics (astro-ph.SR) Fluid Dynamics (physics.flu-dyn)
2010/12/29
Hot luminous stars show a variety of phenomena in their photospheres and in their winds which still lack clear physical explanations at this time. Among these phenomena are non-thermal line broadening...
Transmission Spectra of Transiting Planet Atmospheres: Model Validation and Simulations of the Hot Neptune GJ 436b for JWST
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/29
We explore the transmission spectrum of the Neptune-class exoplanet GJ 436b, including the possibility that its atmospheric opacity is dominated by a variety of non- equilibrium chemical products. We ...
The Decrease of Specific Angular Momentum and the Hot Toroid Formation: The Massive Clump G10.6-0.4
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
This is the first paper of our series of high resolution (1") studies of the massive star forming region G10.6--0.4. We present the emission line observations of the hot core type tracers (O$^{13}$CS,...
