Survey for Transiting Extrasolar Planets in Stellar Systems. II. Spectrophotometry and Metallicities of Open Clusters
J. L. Marshall, Christopher J. Burke, D. L. DePoy +2
We present metallicity estimates for seven open clusters based on spectrophotometric indices from moderate-resolution spectroscopy. Observations of field giants of known metallicit…
Systematic Analysis of 22 Microlensing Parallax Candidates
Shawn Poindexter, Cristina Afonso, David P. Bennett +4
We attempt to identify all microlensing parallax events for which the parallax fit improves Δχ^2 > 100 relative to a standard microlensing model. We outline a procedure to identify…
Probing the Shape of the Galactic Halo with Hyper-Velocity Stars
Oleg Y. Gnedin, Andrew Gould, Jordi Miralda-Escude +1
Precise proper motion measurements (sigma_mu ~ 10 mkas/yr) of the recently discovered hyper-velocity star (HVS) SDSS J090745.0+024507 would yield significant constraints on the axi…
E = mc^2 Without Relativity
Andrew Gould
The equivalence of mass and energy is indelibly linked with relativity, both by scientists and in the popular mind. I prove that E = mc^2 by demanding momentum conservation of an o…
Probing MACHOs Toward the Galactic Bulge
Andrew Gould
If the massive compact halo object (MACHO) fraction of the Galactic dark halo is f ~ 20% as suggested by some microlensing experiments, then about 1.2% of lensing events toward the…
