On the Blazhko Effect in RR Lyrae Stars
J. Robert Buchler, Zoltan Kollath
The Blazhko effect is a long term, generally irregular modulation of the light curves that occurs in a sizeable number of RR Lyrae stars. The physical origin of the effect has been…
Modulations in Multi-Periodic Blue Variables in the LMC
J. Robert Buchler, Peter R. Wood, R. E. Wilson
As shown by Mennickent, et al(2003), a subset of the blue variable stars in the Large Magellanic Cloud exhibit brightness variability of small amplitude in the period range 2.4 to…
The State of Cepheid Pulsation Theory
J. Robert Buchler
We review the current state of Cepheid modeling and discuss its dominant deficiency, namely the use of time dependent mixing length. Notwithstanding, Cepheid modeling has achieved…
Ultra-low Amplitude Variables in the LMC -- Classical Cepheids, Pop. II Cepheids, RV Tau Stars and Binary Variables
J. Robert Buchler, Peter R. Wood, Igor Soszynski
A search for variable stars with ultra-low amplitudes (ULA), in the millimag range, has been made in the combined MACHO and OGLE data bases in the broad vicinity of the Cepheid ins…
The beat Cepheids in the Magellanic Clouds: an analysis from the EROS-2 database
J. B. Marquette, J. P. Beaulieu, J. R. Buchler +36
A number of microlensing dark-matter surveys have produced tens of millions of light curves of individual background stars. These data provide an unprecedented opportunity for syst…
Beat Cepheids as Probes of Stellar and Galactic Metallicity: The New AGS Abundances
J. Robert Buchler
It is well known that the mere location of a Beat Cepheid model in a Period Ratio \vs Period diagram (Petersen diagram) puts constraints on its metallicity Z. But these bounds are…
