Radial and nonradial oscillations of 44 Tauri
Civelek, R; Kiziloglu, N; Kirbiyik, H (American Astronomical Society, 2001-10-01)
Evolutionary stellar models of 44 Tauri, a multiperiodic delta Scuti star, have been developed theoretically and compared with earlier observational reports. The models depict 44 Tau at the hydrogen-shell-burning stage, when it is in radiative equilibrium with a very thin surface convective layer. Using the models, we performed calculations to obtain radial and nonradial adiabatic oscillation frequencies, and the equations were treated linearly. The results showed that the radial fundamental (6.899 cycles d...
Radial and nonradial oscillations in stars with gravitational potential perturbation
Özel, Nesibe; Civelek, Fevziye Rikkat; Department of Physics (2003)
In this study, the linear adiabatic radial and nonradial oscillations of evolutionary stellar model with 1.80M©, representing the star VI 162 Ori, has been investigated. The already working oscillation program with Cowling approximation, which ig nores the Eulerian perturbation in gravitational potential, has been modified to carry out the radial and nonradial linear adiabatic perturbations of stellar mod els using the Eulerian perturbation in gravitational potential. The new set of equations were solved wi...

Constructing a theoretical model of 1.88 M Q pulsation pro- perties of 63 Her have been analyzed. For the model, in question, pulsa- tion periods in the fundamental mode and first two overtones have been derived by solving the linearized pulsation equations. The model has been found to be vlbrationally stable

Radial excitations of the decuplet baryons
Alıyev, Tahmasıb; Sundu Pamuk, Hayriye (2017-04-10)
The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other theoretical predictions. The results for the masses of the ground state particles as well as the excited Delta and Sigma* states are in good consistency with experimental data. Our results on the excited Xi* and Omega(-) states reveal that the experimentally poorly known Xi(1950) and Ome...
