The Blazhko Effect in RR Lyrae stars: Strong observational support for the oblique pulsator model in three stars
The MACHO Collaboration, C. Alcock, D. R. Alves +17
Using the novel data set of the MACHO project, we show that three ``Blazhko Effect'' RR Lyrae stars show nearly-pure amplitude modulation of a single pulsation mode. This is strong…

The MACHO Project SMC Variable Star Inventory: I. The Second-overtone Mode of Cepheid Pulsation From First/Second Overtone (1H/2H) Beat Cepheids
The MACHO Collaboration, C. Alcock, R. A. Allsman +16
We report the discovery of 20 1H/2H and 7 F/1H beat Cepheids in the SMC by the MACHO Project. We utilize the 20 1H/2H stars to determine lightcurve shape for the SMC second-overton…

Bulge delta Scuti Stars in the MACHO Database
The MACHO Collaboration, C. Alcock, R. A. Allsman +20
We describe the search for delta Scuti stars in the MACHO database of bulge fields. Concentrating on a sample of high amplitude delta Scutis, we examine the light curves and pulsat…
