Variable Stars in M31's Globular Clusters
David R. Alves, Alex Bergier, Arlin Crotts +1
This paper has been withdrawn.
Variability-Selected Quasars in MACHO Project Magellanic Cloud Fields
M. Geha, C. Alcock, R. A. Allsman +22
We present 47 spectroscopically-confirmed quasars discovered behind the Magellanic Clouds identified via photometric variability in the MACHO database. Thirty-eight quasars lie beh…
K-Band Red Clump Distance to the Large Magellanic Cloud
David R. Alves, Marina Rejkuba, Dante Minniti +1
The Hipparcos I-band calibration of horizontal-branch red clump giants as standard candles has lead to controversial results for the distance to the Large Magellanic Cloud (LMC). I…
New Understanding of Large Magellanic Cloud Structure, Dynamics and Orbit from Carbon Star Kinematics
Roeland P. van der Marel, David R. Alves, Eduardo Hardy +1
We derive general expressions for the LMC velocity field which we fit to kinematical data for 1041 carbon stars. We demonstrate that all previous studies of LMC kinematics have mad…
MACHO Project Analysis of the Galactic Bulge Microlensing Events with Clump Giants as Sources
P. Popowski, T. Vandehei, K. Griest +19
We present preliminary results of the analysis of 5 years of MACHO data on the Galactic bulge microlensing events with clump giants as sources. This class of events allows one to o…
The MACHO Project LMC Variable Star Inventory: XII. Three Cepheid Variables in Eclipsing Binaries
C. Alcock, R. A. Allsman, D. R. Alves +22
We present a method for solving the lightcurve of an eclipsing binary system which contains a Cepheid variable as one of its components as well as the solutions for three eclipsing…
