Cygni , a second overtone field RR Lyrae star
We present the first (as of February, 1999) UBV and uvby photometric measurements for the short period variable star V2109 Cyg discovered by the Hipparcos satellite and classified as a field RRc variable. We have obtained new times of maxima and the period change has been studied. We determined the fundamental physical parameters using the geometric distance of the star and the most recent synt...
متن کاملThe RR Lyrae Star Period – K - band Luminosity Relation of the Globular Cluster
That the RR Lyrae star period – K-band luminosity relation is a promising tool as a distance indicator in the Milky Way and Local Group of Galaxies is apparent on observational and theoretical grounds in the literature. Less clear is the sensitivity of the relation, and consequently the physics of horizontal branch stars, to differences in stellar environment. In this paper, the first measureme...
متن کاملThe Blazhko Effect of the RR Lyrae Star FM Persei
We have obtained 615 new V and R observations of the RR Lyrae star FM Per. A period search identified a primary period of 0.489256 days; however, the light curve of FM Per cannot be well described by a single period. We conclude that FM Per demonstrates the Blazhko effect with a Blazhko period of approximately 122 days.

متن کاملThe Macho Project Lmc Variable Star Inventory. Ix. Frequency Analysis of the First Overtone Rr Lyrae Stars and the Indication for Nonradial Pulsations
More than 1300 variables classified provisionally as first overtone RR Lyrae pulsators in the macho variable star database of the Large Magellanic Cloud (LMC) have been subjected to standard frequency analysis. Based on the remnant power in the prewhitened spectra, we found 70% of the total population to be monoperiodic. The remaining 30% (411 stars) are classified as one of 9 types according t...
