The rotation period-activity luminosity and the rotation period-surface activity flux correlations for the components of RS CVn-type binaries are discussed. It is argued that such correlations, although they are required by dynamo generated magnetic fields, do not represent the dominant parameter in determining the level of activity. Evidences are given that these correlations may essentially be induced by the period-radius dependence for the components of RS CVn-type binaries, and in addition, this result may well be valid for all the late-type stars (single or binary components).

BV observations of W UMa-type binaries: CK Boo, BI CVn, and AH Vir Demircan, Osman (Springer Science and Business Media LLC, 1987-7) Photoelectric BV observations of W UMa-type binaries CK Boo, BI CVn, and AH Vir are presented, and light curve variations and shifts of minima are discussed in the context of stellar activity and mass transfer. The O−C increments in three systems were found to be 0.08, 0.80, and 0.60 s per revolution, respectively. The new ephemeris for the future observations were also found.
Pre-Main-Sequence evolution of rotating low-mass stars Kızıloğlu, Nilgün (Springer Science and Business Media LLC, 1989-4) The evolutionary behaviour of rotating low-mass stars in the mass range 0.2 and 0.9M ⊙ has been investigated during the pre-Main-Sequence phase. The angular momentum is conserved locally in radiative regions and totally in convective regions, according to a predetermined angular velocity distribution depending on the structure of the star. As the stars contract toward the zero-age Main Sequence, they spin up under the assumption that the angular momentum is conserved during the evolution of the stars. When ...
The momentum 4-vector imparted by gravitational waves in Bianchi-type metrics Havare, A; Korunur, M; Salti, M (Springer Science and Business Media LLC, 2006-01-01) Considering the MOller, Weinberg and Qadir-Sharif's definitions in general relativity, we find the momentum 4-vector of the closed universe based on the Bianchi-type metrics. The momentum 4-vector (due to matter plus fields) is found to be zero. This result supports the viewpoints of Albrow and Tryon and extends the previous works by Cooperstock-Israelit, Rosen, Johri et al., Banerjee-Sen and Vargas who investigated the problem of the energy in Friedmann-Robertson-Walker universe and SaltI-Havare who studie...
Frequency-resolved spectroscopy of XB1323-619 using XMM-Newton data: detection of a reflection region in the disc Balman, Şölen (Oxford University Press (OUP), 2010-09-21) We present the frequency-resolved energy spectra (FRS) of the low-mass X-ray binary dipper XB1323-619 during persistent emission in four different frequency bands using an archival XMM-Newton observation. FRS method helps to probe the inner zones of an accretion disc. XB1323-619 is an Atoll source and a type-I burster. We find that the FRS is well described by a single blackbody component with kT in a range 1.0-1.4 keV responsible for the source variability in the frequency ranges of 0.002-0.04 and 0.07-0.3...
CORRELATION BETWEEN BOLOMETRIC AND X-RAY LUMINOSITIES IN RS CVN-TYPE BINARIES DEMIRCAN, O (Springer Science and Business Media LLC, 1987-10-01) Re-analysis of the X-ray emission from RS CVn-type binaries has revealed that-contrary to the claims by many authors-their coronal activity is not independent of bolometric luminosity (and thus mass). It becomes clear that activity in late-type stars is also powered-just as in the case of early-type stars-mostly by photospheric radiation.
