The role of the initial surface density profiles of the disc on giant planet formation: comparing with observations
the initial surface density profiles the disc on giant planet formation
2011/1/10
In order to explain the main characteristics of the observed population of extrasolar planets and the giant planets in the Solar System, we need to get a clear understanding of which are the initial c...
Measuring the escape velocity and mass profiles of galaxy clusters beyond their virial radius
gravitation galaxies clusters general techniques miscellaneous cosmology miscellaneous cosmology
2010/11/9
The caustic technique uses galaxy redshifts alone to measure the escape velocity and mass profiles of galaxy clusters to clustrocentric distances well beyond the virial ra-dius, where dynamical equili...
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...
Galaxy clustering and projected density profiles as traced by satellites in photometric surveys: Methodology and luminosity dependence
Galaxy clustering projected density profiles photometric surveys
2010/11/12
We develop a new method which measures the projected density distribution wp(rp)n of photometric galaxies surrounding a set of spectroscopically-identified galaxies, and simultaneously the projected c...
Modelling chromospheric line profiles as diagnostics of velocity fields in ω Centauri red giant stars
line profiles globular clusters individual atmospheres mass loss
2010/11/11
Context. Mass loss of ∼ 0.1-0.3 M⊙ from Population II red giant stars (RGB) is a requirement of stellar evolution theory in order to account for several observational evidences in globular clust...
Asymmetric Line Profiles in Spectra of Gaseous Metal Disks Around Single White Dwarfs
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
Around several single DAZ and DBZ white dwarfs metal-rich disks have been observed, which are mostly believed to originate from disruption of smaller rocky planetesimals. In some cases the material do...
The Origin of Dark Matter Halo Profiles
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/29
A longstanding puzzle of fundamental importance in modern cosmology has been the origin of the nearly universal density profiles of dark matter halos found in N-body simulations -- the so-called NFW p...
Iron line profiles in Suzaku spectra of bare Seyfert galaxies
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
We methodically model the broad-band Suzaku spectra of a small sample of six 'bare' Seyfert galaxies: Ark 120, Fairall 9, MCG-02-14-009, Mrk 335, NGC 7469 and SWIFT J2127.4+5654. The analysis of bare ...

Optical-turbulence and wind profiles at San Pedro Mártin。
We investigate the causal temperature profiles in a recent model of a radiating star undergoing dissipative gravitational collapse without the formation of a horizon. It is shown that this simple exac...

THE INFLUENCE OF HYPERFINE STRUCTURE ON SOME MANGANESE LINE PROFILES IN THE SOLAR SPECTRUM
Sun photosphere–Line profiles–techniques spectroscopic
2009/3/11
Taking into account effects of hyperfine structure, we calculated
the synthetic solar spectrum for wavelength intervals around nine neutral manganese
lines. To estimate values of hyperfine component...
