Theoretical Study of Cepheid Light Curves

Classical Cepheid Light Curves Revisited

The Structural Properties Of Cepheid Light Curves

Fourier decompositions are performed for the V magnitude variations of a sample of 57 Cepheids ranging in period from 2 to 17 days. The coefficients have been tabulated to allow rapid reconstruction of the light curves. It is shown that combinations of the low-order coefficients quantitatively describe the progression of curve shape with period. The pulsation amplitude plays only a minor role. ...

Properties of theoretical RRab light curves

Using an adaptive radiation hydrodynamics code we have computed a grid of fundamental mode RR Lyrae models in order to give a detailed comparison to observed RR Lyrae light curves and to investigate the influence of several numerical parameters inherent to the computational method. The results can be summarized as follows: Concerning the comparison to observations the proposed solution of the w...

Structural Properties of s - Cepheid Velocity Curves ⋆

The light curves of the first overtone Pop. I Cepheids (s-Cepheids) show a discontinuity in their φ 21 vs. P diagram, near P = 3.2 day. This feature, commonly attributed to the 2:1 resonance between the first and the fourth overtones (ω 4 ≈ 2ω 1), is not reproduced by the hydrodynamical models. With the goal of reexamining the resonance hypothesis, we have obtained new CORAVEL radial velocity c...

gradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism

ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
