An attempt has been made towards explaining the observed frequencies in 63 Her. The evolution of rotating stars of 1.96, 1.98, 2.00, 2.05 and 2. 10 M-circle dot have been studied up to a point where stellar parameters match the observed luminosity and effective temperature of 63 Her. Radial and nonradial adiabatic oscillation frequencies were obtained in low harmonic degrees ( 1 = 0,1,2,3). One radial and three nonradial frequency values that match with the observed values were found for the model of mass 2.00 M-circle dot.

The first resolved and detected classical nova shell in X-rays: The shell of Nova Persei 1901
Balman, Şölen; Ogelman, HB (IOP Publishing, 1999-06-20)
We present the ROSAT High-Resolution Imager data of the first resolved and detected classical nova shell in the X-ray wavelengths: the shell of Nova Persei 1901. We find that the X-ray nebula is composed of knots/clumps and has an elliptical shape with a total count rate of about 0.01 +/- 0.001 counts s(-1). We estimate that the spectrum is of thermal origin with a luminosity of similar to 8.0 x 10(31) ergs s(-1) and an X-ray temperature of similar to 2.0 x 10(6) K in the 0.1-2.4 keV energy range. The knots...
The X-ray spectral evolution of classical Nova V1974 Cygni 1992: A reanalysis of the ROSAT data
Balman, Şölen; Krautter, J; Ogelman, H (IOP Publishing, 1998-05-20)
We present a spectral analysis of the archival X-ray data of classical Nova V1974 Cygni 1992 (Nova Cygni 1992) obtained by the ROSAT Position Sensitive Proportional Counter (PSPC). The X-ray spectrum is fitted with a two-component model. The first component is a white dwarf atmosphere emission model developed for the remnants of classical novae near the Eddington luminosity. The model is used to fit the soft X-ray data in the similar to 0.1-1.0 keV range, where the bulk of emission is below 0.7 keV. The sec...
A Study on W Ursae Majoris-Type Systems Recognised by the ROTSE-IIId Experiment
Coker, D.; ÖZDEMİR, SACİT; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; AKSAKER, NAZIM; Gucsav, B. B. (Cambridge University Press (CUP), 2013-01-24)
We present a study on characterising the light curves of W UMa-type systems gathered from the archive containing 5 years of data observed with the Robotic Optical Transient Search Experiment Telescope (ROTSE-IIId) located in Turkey. A sample of 45 W UMa-type systems was studied on the basis of Fourier decomposition of light curves and some basic geometrical parameters, namely degree of contact (f), mass ratio (q), and orbital inclination (i), as approximated values for these systems were determined. Moreove...
Comprehensive analysis of the transient X-ray pulsar MAXI J1409 619
Donmez, C. K.; Serim, Muhammed Miraç; Inam, S. C.; Sahiner, S.; Serim, D.; Baykal, Altan (Oxford University Press (OUP), 2020-08-01)
We probe the properties of the transient X-ray pulsar MAXI J1409-619 through RXTE and Swift follow-up observations of the outburst in 2010. We are able to phase-connect the pulse arrival times for the 25 d episode during the outburst. We suggest that either an orbital model (with P-orb similar or equal to 14.7(4) d) or a noise process due to random torque fluctuations (with S-r approximate to 1.3 x 10(-18) Hz(2) S-2 Hz(-1)) is plausible to describe the residuals of the timing solution. The frequency derivat...
X-ray spectral evolution of Her X-1 in a low state and the following short high state
Inam, SC; Baykal, Altan (Oxford University Press (OUP), 2005-08-21)
We analysed spectral variations of similar to 8.5-d long Rossi X-ray Timing Explorer (RXTE) monitoring observations of Her X-1 in 2001 December. This set of observations enables, for the first time, frequent continuous monitoring (111 pointings in similar to 8.5 d) of the source with RXTE including a similar to 1.7-d-long low state part and the following similar to 6.8-d-long short high state part. We used an absorbed power-law model with an iron line energy complex modelled as a Gaussian to fit both the 3-...
