A Comprehensive Analysis of Uncertainties Affecting the Stellar Mass - Halo Mass Relation for 0
dark matter galaxies abundances galaxies evolution galaxies stellar content methods N-body simulations
font style='font-size:12px;'>
2010/3/8
We conduct a comprehensive analysis of the relationship between central galaxies and their host dark matter halos, as characterized by the stellar mass-halo mass (SM-HM) relation, with rigorous consid...
On Out of Plane Equilibrium Points in Photo-Gravitational Restricted
Radiation—Poynting–Robertson drag—binary stellar system—equilibrium points—stability
font style='font-size:12px;'>
2010/9/15
We have investigated the out of plane equilibrium points of a passive micron size particle and their stability in the field of radiating binary stellar systems Kr¨uger-60, RW-Monocerotis within the fr...
Close Separation Triple System QSO 1009–0252 with Discordant Redshifts:
Quasars emission lines absorption lines—individual

2010/9/15
1009-0252 is a Quasi Stellar Object (QSO) with three components A, B, C. A, B are thought to be the result of gravitational lensing of one object, and A, C constitute a close pair with redshifts 2.74 ...
本文接续《揭示色散隐含的深层秘密》，将“CZS折光理论”向广义时空拓展，推得“万有引力本质为引力场的折光效应”，并得到折光效应中的重要方程组；最终破解了“引力作功中粒子速度极限的困惑”，破解了“光线在引力场异常红移现象”。

2009/3/18
Electron-, proton-, and ionized helium-impact broadening parameter
tables for neutral calcium spectral lines, have been presented as a function of the
temperature and the perturber density. Calculat...
ORBIT ORIENTATION FOR BINARIES WITH ORBITAL INCLINATION i = 90
ORBIT ORIENTATION BINARIES ORBITAL INCLINATION i = 90
font style='font-size:12px;'>
2009/3/18
Among more than 1000 binaries there are 20 systems with orbital
inclination i = 90o ± 3o. Their spatial orientation is examined. It is concluded
that almost 50% of them have quasi complanar orientat...
Velocity Curve Studies of Spectroscopic Binary Stars V380 Cygni, V401 Cyg, V523 Cas, V373 Cas and V2388 Oph
Stars binaries eclipsing—stars binaries spectroscopic

2010/9/15
Closed system of time equations for nonrelativistic gravitation field and hydrodynamic medium was obtained by taking into account binary correlations of the field, which is the generalization of Jeans...
Kinematical Diagrams for Conical Relativistic Jets
Blazars general—galaxies active quasars jets nuclei radio continuum
font style='font-size:12px;'>
2010/9/16
We present diagrams depicting the expected inter-dependences of two key kinematical parameters of radio knots in the parsec-scale jets of blazars, deduced from VLBI observations. The two parameters ar...
