V371 Per — A thick-disk, short-period F/1O Cepheid
V371 Per was found to be a double-mode Cepheid with a fundamental mode period of 1.738 days, the shortest among Galactic beat Cepheids, and an unusually high period ratio of 0.731, while the other Galactic beat Cepheids have period ratios between 0.697 and 0.713. The latter suggests that the star has a metallicity [Fe/H] between −1 and −0.7. The derived distance from the Galactic plane places i...
متن کاملOn The Short-Period Type II Cepheid Field Stars
Fourier decomposition parameters for the photoelectric light curves of 20 short-period type II Cepheids in the field are compared with the models of Hodson, Cox, and King, also subjected to Fourier analysis. The hydrodynamic light curves display sequences in the Fourier phases very reminiscent of the resonance progressions among classical Population I Cepheids with periods less than 10 days. Ho...
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 ...
متن کاملMining Sky Surveys for Astrophysically Interesting Variable Stars: The Cepheid Period Range
We have undertaken a project to discover new type I1 Cepheids in two large-area sky surveys. However, most of the candidates from the surveys differ from type I1 Cepheids in their amplitude and period distributions and they form a separate, cooler sequence relative to the Cepheids in a temperature-gravity plot. We refer to these objects as "Cepheid-lke" stars. Many e h b i t unstable pulsation ...
متن کاملOn the Normalizationof Cepheid Period-luminosity Relationships
Results of stellar evolution calculations and results of non-adiabatic stellar pulsation calculations can be used to construct theoretical , composition-dependent, short period boundaries (or \blue edges") of the instability strip in the period-luminosity plane for Cepheids pulsating in the fundamental and rst overtone radial modes. The slopes of these blue edges are very similar to the slopes ...
