The galactic double – mode Cepheids
By considering the least–squares fits of the double–mode Cepheid light curves discussed in Paper I we defined their properties by their Fourier parameters and generalized phase differences G i,j. When plotting the latter quantities as a function of the respective order, the second order terms are confined in the region just below 3/2π; the third order terms have π/2 < G i,j < π, the fourth orde...
متن کاملThe galactic double–mode Cepheids I. Frequency analysis of the light curves and comparison with single–mode Cepheids
We submitted the available photometric V data of all the known galactic Double Mode Cepheids (DMCs) to a careful frequency analysis with the aim of detecting in each case the importance of the harmonics and of the cross coupling terms. For each object, starting from different data subsets, we progressively built a homogenous set of data, checking the consistency of the results step by step. It ...
متن کاملCompression mode giant resonances
Compression mode giant resonances have been measured in many nuclei from C to Pb with inelastic scattering of 240 MeV particles at small angles. Isoscalar monopole distributions have been extracted for 17 nuclei and isoscalar dipole distributions extracted for 11 nuclei. The E0 strength distributions in Zr, Sn, Sm and Pb have been measured precisely and in Sn, Sm and Pb were found to be concent...
متن کاملSearch for second overtone mode Cepheids in the Magellanic Clouds
Accurate CCD observations of three Cepheids in the SMC were made with the purpose of confirming their nature of second overtone mode Cepheids. The stars were suspected pulsating in the second overtone mode owing to the unusual light curve and short period reported by Payne-Gaposchkin & Gaposchkin (1966). The analysis of the new data shows that for two stars the previous periods are wrong, and i...
متن کاملStudy of transient double-mode behaviour of nonlinear models of Cepheids
Nonlinear pulsation models of Cepheids pulsating in first and second overtone modes have been constructed in order to study their transient double-mode behaviour. The purposes were to: (1) verify the possible nonlinear effects on period ratios; (2) compare the general nonlinear characteristics of the theoretical light curves with the observed ones; (3) check the plausibility of the hypothesis o...
