On resonant and non-resonant origin of double-mode Cepheid pulsation
Double-mode Cepheid behaviour may arise either from non-resonant or resonant mode interaction. Inclusion of turbulent convection into pulsation codes by Kolláth et al. led to stable double-mode F+1O Cepheid pulsation [1]. However, our recent computations indicate, that these models resulted from incorrect neglect of negative buoyancy effects [2]. Once these effects are taken into account, only ...

15 صفحه اولnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
15 صفحه اولOn the pulsation mode identification of short-period Galactic Cepheids
We present new theoretical Period-Radius (PR) relations for first overtone Galactic Cepheids. Current predictions are based on several sequences of nonlinear, convective pulsation models at solar chemical composition (Y=0.28, Z=0.02) and stellar masses ranging from 3.0 to 5.5 M . The comparison between predicted and empirical radii of four short-period Galactic Cepheids suggests that QZ Nor and...
متن کامل8 - Stellar Pulsation and Oscillation
That some stars vary in brightness has been known from time immemorial. That this variation is the result of intrinsic changes in the star itself has been known for less than 100 years and the causes of those variations have been understood for less than 30 years. It is not a simple matter to distinguish the light variations resulting from eclipses by a companion from those caused by physical c...
