The Mass of the MACHO-LMC-5 Lens Star (2004)
Gould, Andrew, Bennett, David P., Alves, David R.
We combine the available astrometric and photometric data for the 1993 microlensing event MACHO-LMC-5 to measure the mass of the lens, M=0.097 +/- 0.016 Msun. This is the most precise direct mass...
Recently obtained kinematic data has shown that the Large Magellanic Cloud (LMC) possesses an old stellar halo. In order to further characterize the properties of this halo, parametric King models...

A Review of the Distance and Structure of the Large Magellanic Cloud (2003)
The average of 14 recent measurements of the distance to the Large Magellanic Cloud (LMC) implies a true modulus of 18.50 +- 0.02 mag, and demonstrates a trend in the past 2 years of convergence...
Kinematic Evidence for an Old Stellar Halo in the Large Magellanic Cloud (2003)
Minniti, Dante, Borissova, Jura, Rejkuba, Marina, Alves, David R., Cook, Kem H., Freeman, Kenneth C.
The oldest and most metal-poor Milky Way stars form a kinematically hot halo, which motivates the two major formation scenarios for our galaxy: extended hierarchical accretion and rapid collapse. RR...

K-Band Red Clump Distance to the Large Magellanic Cloud (2002)
Alves, David R., Rejkuba, Marina, Minniti, Dante, Cook, Kem H.
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). In an attempt to...
Van Der Marel, Roeland P., Alves, David R., Hardy, Eduardo, Suntzeff, Nicholas B.
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 made unnecessary...
Post-AGB Stars in Globular Clusters and Galactic Halos (2001)
Bond, Howard E., Alves, David R.
We discuss three aspects of post-AGB (PAGB) stars in old populations. (1) HST photometry of the nucleus of the planetary nebula (PN) K 648 in the globular cluster (GC) M15 implies a mass of 0.60...

Hubble Space Telescope Observations of the Planetary Nebula K648 in the Globular Cluster M15 (2000)
Alves, David R., Bond, Howard E., Livio, Mario
We have obtained observations of the planetary nebula K648 in the Galactic globular cluster M15 with the Hubble Space Telescope's WFPC2 camera, covering an interval of 7 days. The frames provide both...
The Rotation Curve of the Large Magellanic Cloud and the Implications for Microlensing (2000)
Alves, David R., Nelson, Cailin A.
The rotation of the disk of the Large Magellanic Cloud (LMC) is derived from the radial velocities of 422 carbon stars. New aspects of this analysis include the propagation of uncertainties in the...
K-Band Calibration of the Red Clump Luminosity (2000)
The average near-infrared (K-band) luminosity of 238 Hipparcos red clump giants is derived and then used to measure the distance to the Galactic center. These Hipparcos red clump giants have been...
Alves, David R., Sarajedini, Ata
Color-magnitude diagrams of globular clusters often exhibit a prominent horizontal branch (HB) and may also show features such as the red giant branch (RGB) bump and the asymptotic giant branch (AGB)...
Ground-based Discovery of Cepheids and Miras in M101 (1995)
We have identified 4 Cepheids and 5 Miras using KPNO 4m BVRI images of an outer field in M101. The Cepheid and Mira periods range from 30 to 60 days and 350 to 800 days, respectively. We derive...
