Surface brightness profiles for 23 M31 star clusters were measured using images from the Wide Field Planetary Camera 2 on the Hubble Space Telescope, and fit to two types of models to determine the...
Fast Winds and Mass Loss from Metal-Poor Field Giants (2009)
Dupree, A. K., Smith, G. H., Strader, J.
Spectra of the He I 10830 Angstrom line were obtained with NIRSPEC on the Keck 2 telescope for metal-deficient field giant stars. This line is ubiquitous in stars with T_eff greater than 4500K and...
Hodge, P. W., Krienke, O. K., Bellazzini, M., Perina, S., Barmby, P., Cohen, J. G., ...
We report on the properties of 89 low-mass star clusters located in the vicinity of luminous young clusters ("blue globulars") in the disk of M31. Eighty-two of the clusters are newly detected. We...
Star Cluster Candidates in M81 (2009)
Nantais, J. B., Huchra, J. P., McLeod, B., Strader, J., Brodie, J. P.
We present a catalog of extended objects in the vicinity of M81 based a set of 24 Hubble Space Telescope Advanced Camera for Surveys (ACS) Wide Field Camera (WFC) F814W (I-band images. We have found...

Spatially resolved spectroscopy of early-type galaxies over a range in mass (2007)
Sanchez-Blazquez, P., Forbes, D. A., Strader, J., Brodie, J., Proctor, R.
Long-slit spectra have been obtained with the Keck telescope for a sample of 11 early-type galaxies covering a wide range in luminosity and hence mass. Rotation velocity and velocity dispersions,...
HST/ACS Wide-Field Photometry of the Sombrero Galaxy Globular Cluster System (2006)
Spitler, L. R., Larsen, S. S., Strader, J., Brodie, J. P., Forbes, D. A., Beasley, M. A.
A detailed imaging analysis of the globular cluster (GC) system of the Sombrero galaxy (NGC 4594) has been accomplished using a six-image mosaic from the Hubble Space Telescope Advanced Camera for...
ChaMPlane Discovery of Candidate Symbiotic Binaries in Baade's and Stanek's Windows (2006)
Berg, M. Van Den, Grindlay, J., Laycock, S., Hong, J., Zhao, P., Koenig, X., ...
We have searched the OGLE-II archive for candidate counterparts of X-ray sources detected in two low-extinction windows included in our Galactic bulge Chandra/HST survey. We find that a significant...
