Mass loss and orbital period decrease in detached chromospherically active binaries
The secular evolution of the orbital angular momentum (OAM), the systemic mass (M = M1+M2) and the orbital period of 114 chromospherically active binaries (CABs) were investigated after determining the kinematical ages of the sub-samples which were set according to OAM bins. OAMs, systemic masses and orbital periods were shown to be decreasing by the kinematical ages. The first order decreasing...
متن کاملPhotometric Solutions for Semi-Detached Eclipsing Binaries: Selection of Distance Indicators in the Small Magellanic Cloud
Estimation of distances to nearby galaxies by the use of eclipsing binaries as standard candles has recently become feasible because of new large scale instruments and the discovery of thousands of eclipsing binaries as spinoff from Galactic microlensing surveys. Published measurements of distances to detached eclipsing binaries in the Large Magellanic Cloud combine stellar surface areas (in ab...
متن کاملThe Possible Nature of Dips in the Light Curves of Semi-Detached Binaries with Stationary Disks
A thickening at the outer edge of the accretion disk is usually invoked to explain the dips in the light curves of cataclysmic variables with stationary disks at phases ∼ 0.7. The non-collisional interaction between the stream and the disk in the stationary solution raises the question of why matter appears at a considerable height above the accretion disk in such systems. Our three-dimensional...
متن کاملSix detached white - dwarf close binaries ⋆
We determine the orbits of four double degenerate systems (DDs), composed of two white dwarfs, and of two white dwarf – M dwarf binaries. The four DDs, WD1022+050, WD1428+373, WD1824+040, and WD2032+188, show orbital periods of 1.157155(5) d, 1.15674(2) d, 6.26602(6) d and 5.0846(3) d respectively. These periods combined with estimates for the masses of the brighter component, based on their ef...
متن کاملDetached and Interacting Ob Star Binaries
We present an analysis of detached and interacting OB star binaries. Values of masses, radii, and internal structure constants from stars in detached systems are in excellent agreement with the latest stellar models. Some revisions to the eeective temperature scale for O stars would seem to be required. The mass-exchanging, or interacting, OB binaries discussed in this sample seem to require ca...
