A comparison of Rosseland-mean opacities from OP and OPAL
Monochromatic opacities from the Opacity Project (OP) (Seaton et al.) have been augmented by hitherto missing inner-shell contributions (Badnell & Seaton). OP Rosseland-mean opacities, κR, are compared with results from OPAL (Iglesias & Rogers) for the elements H, He, C, O, S and Fe. The OPAL data are obtained from the website www-phys.llnl.gov/Research/OPAL/index.html. Agreement for H is close...
متن کاملNonlinear Beat Cepheid and RR Lyrae Models
The numerical hydrodynamic modelling of beat Cepheid behavior has been a long standing quest in which purely radiative models had failed consistently. We find that beat pulsations occur naturally when turbulent convection is accounted for in our hydrodynamics code. The development of a relaxation code and of a Floquet stability analysis greatly facilitates the search for and the analysis of bea...
متن کاملComparative Pulsation Calculations with Op and Opal Opacities
Comparative linear nonadiabatic pulsation calculations are presented using the OPAL and Opacity Project opacities. The two sets of opacities include effects due to intermediate coupling and fine structure as well as new abundances. We used two mass luminosity (M L) relations, one standard (BIT), and one employing substantial convective core overshoot (CO V). The two sets of opacities cannot be ...
متن کاملOpacity, Metallicity, and Cepheid Period Ratios in the Galaxy Andmagellanic Clouds
Linear pulsation calculations are employed to reproduce the bump Cepheid resonance (P 2/Po = 0.5 at Po ~ 10 days) and to model, individually, the PdPo period ratios for the dozen known Galactic beat Cepheids. Convection is ignored. The results point to a range of metallicity among the Cepheids, perhaps as large as 0.01 ~ Z ~ 0.02, with no evidence for any star exceeding Z = 0.02. We find masses...
متن کاملThe Intermediate-period Cepheid Strip Stars
To explore the population of variable stars that fall between RR Lyrae stars and classical Cepheids, we have obtained extensive photometric observations for 56 stars with periods between 0.6 and 1.0 days. For these stars and an additional 10, we have examined the form and stability of the light curves to explore the variety of types of stars in this period regime. We conclude that the majority ...
