Third Order Effect of Rotation on Stellar Oscillations of a -Cephei Star
K. Karami
Here the effect of rotation up to third order in the angular velocity of a star on the p, f and g modes is investigated. To do this, the third-order perturbation formalism presente…
The effects of twisted magnetic field on coronal loops oscillations and dissipation
K. Karami, M. Barin
The standing MHD modes in a zero- cylindrical magnetic flux tube modelled as a straight core surrounded by a magnetically twisted annulus, both embedded in a straight ambient ex…
Application of a New Non-Linear Least Squares Velocity Curve Analysis Technique for Spectroscopic Binary Stars
K. Karami, R. Mohebi, M. M. Soltanzadeh
Using measured radial velocity data of nine double lined spectroscopic binary systems NSV 223, AB And, V2082 Cyg, HS Her, V918 Her, BV Dra, BW Dra, V2357 Oph, and YZ Cas, we find c…
Resonant absorption in dissipative flux tubes
H. Safari, S. Nasiri, K. Karami +1
We study the resonant absorption of MHD waves in magnetized flux tubes with a radial density inhomogeneity. Within the approximation that resistive and viscous processes are operat…
Third Order Effect of Rotation on Stellar Oscillations of a B Star
K. Karami
The present paper aims at investigating the effect of rotation up to third order in the angular velocity of a star on p and g modes, based on the formalism developed by Soufi et al…
Radial velocity-acceleration curve analysis of the spectroscopic binary stars by the nonlinear regression
K. Karami, H. Teimoorinia
We will introduce a new method to derive the orbital elements of the spectroscopic binary stars. Fitting the adopted radial velocity curves on the measured experimental data, the c…
