The inclination of the orbital planes of 78 visual binaries with known orbits with respect to the galactic was examined. No double star groupings were found having approximately equal orientation of...
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...
We find that any really close concentration of positions of poles of orbital planes for binaries is not affected by the corresponding positions of ”mirror poles” for the same orbital planes. Namely,...
ORBITS OF 6 BINARIES     binaries  visual       2009/3/6
In this paper the orbits of binaries WDS 10093+2020 = A 2145, WDS 21074􀀀0814 = BU 368 AB and WDS 22288􀀀0001 = STF 2909 AB are re- calculated because of significant deviations of mo...
Orientations of orbital planes of binaries are analysed by using a complete sample of known orbital systems. The use of a so large sample is possible due to the application of a new procedure enabli...
期刊信息 篇名 A New Generation Solution Model for Predicting Thermodynamic Properties of Multicomponent system From Binaries 语种 英文 撰写或编译 撰写 作者 周国治,魏寿昆 第一作者单位 北京科技大学 刊物名称 Metallurgical Transactions 页面 1997,V...
Searching for X-ray binaries projected on open clusters (OCs) and supernova remnants (SNRs), associations of X-ray binaries with OCs and SNRs in the Galaxy are discussed. Three of the high mass X-ray ...
We re-analysed the behaviour of coronal activity of the RS CVn-type binaries as a function of stellar and orbital parameters. Highly significant correlations were found between the x-ray luminosity Lx...
Space motions of RS CVn and W UMa binaries have been calculated using parallaxes and proper motions from Hipparcos catalogue and radial velocities from the literature. We have calculating the mean mot...
The orbital angular momentum (orbital AM) of a sample of forty RS CVn-type binaries with the orbital periods P \leq 10 days were estimated and the orbital AM distribution with respect to P was critica...
The orbital period changes in some chromospherically active close binaries have been interpreted as a consequence of magnetic activity. At least in two active close binaries a possible relationship be...
Two groups of late-type very close main sequence binaries, the so-called short-period RS Canum Venaticorum (RS CVn) and W Ursae Majoris (W UMa) systems, are important for the understanding of the stru...
Accurate monitoring of the orbital period of late-type close binaries can provide important information on their secular evolution and on the structural changes of their components on very short times...
The long-term period variations of the classical algol-type binaries XZ And, U Cep, b Per, RT Per, ST Per and TX UMa were studied by using all available observed times of eclipse minima. The (O-C) dia...
