Significance of tension for gravitating masses in Kaluza-Klein models
Significance tension gravitating masses Kaluza-Klein models
2012/2/23
In this report, we consider the six-dimensional Kaluza-Klein models with spherical compactification of the internal space. Here, we investigate the case of bare gravitating compact objects with the du...
Study of measured pulsar masses and their possible conclusions
measured pulsar masses possible conclusions
2011/1/11
We study the statistics of 61 measured masses of neutron stars (NSs) in binary pulsar systems, including 18 double NS (DNS) systems, 26 radio pulsars (10 in our Galaxy) with white dwarf (WD) companion...
Dynamical neutrino masses in the generalized Chaplygin gas scenario with mass varying CDM
neutrino masses generalized Chaplygin gas scenario mass varying CDM
2010/11/10
Neutrinos coupled to an underlying scalar field in the scenario for unification of mass varying
dark matter and cosmon-like dark energy is examined. In the presence of a tiny component of mass varyin...
Dynamical versus Stellar Masses of Ultracompact Dwarf Galaxies in the Fornax Cluster
galaxies dwarf – galaxies elliptical and lenticular cD – galaxies evo-lution – galaxies stellar content – galaxies kinematics and dynamics
2010/11/12
The origin of ultracompact dwarf (UCD) galaxies, compact extragalactic stellar sys-tems, is still a puzzle for present galaxy formation models. We present the compre-hensive analysis of high resolutio...
WINGS-SPE II: A catalog of stellar ages and star formation histories, stellar masses and dust extinction values for local clusters galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
The WIde-field Nearby Galaxy clusters Survey (WINGS) is a project whose primary goal is to study the galaxy populations in clusters in the local universe (z<0.07) and of the influence of environment o...
The masses, and the mass discrepancy of O-type stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
The "mass discrepancy" in massive O stars represents a long-standing problem in stellar astrophysics with far-reaching implications for the chemical and dynamical feedback in galaxies.
Masses and envelope binding energies of primary stars at the onset of a common envelope
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We present basic properties of primary stars that initiate a common envelope (CE) in a binary, while on the giant branch. We use the population-synthesis code described in Politano et al. (2010) and f...
Brown Dwarf Jets: Investigating the Universality of Jet Launching Mechanisms at the Lowest Masses
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Recently it has become apparent that proto-stellar-like outflow activity extends to the brown dwarf (BD) mass regime. While the presence of accretion appears to be the common ingredient in all objects...
Accurate AGN black hole masses and the scatter in the M_{bh} - L_{bulge} relationship
black hole physics galaxies active galaxies bulges galaxies fundamental parameters galaxies nuclei quasars emission lines
2010/3/9
A new empirical formulae is given for estimating the masses of black holes in AGNs from the H beta velocity dispersion and the continuum luminosity at 5100 Angstroms. It is calibrated to reverberation...
Virial Masses from the Hectospec Cluster Survey (HeCS) and the Sunyaev-Zeldovich Effect
individual galaxies kinematics and dynamics cosmology
2010/3/8
We present the first comparison of a large sample of virial masses of galaxy clusters with their Sunyaev-Zel'dovich (SZE) signals. We study 15 clusters from the Hectospec Cluster Survey (HeCS) with MM...
