HD 91669b: A New Brown Dwarf Candidate from the McDonald Observatory Planet Search (2008)
Wittenmyer, Robert A., Endl, Michael, Cochran, William D., Ramirez, Ivan, Reffert, Sabine, MacQueen, Phillip J., ...
We report the detection of a candidate brown dwarf orbiting the metal-rich K dwarf HD 91669, based on radial-velocity data from the McDonald Observatory Planet Search. HD 91669b is a substellar...
B2 0902+34: A Collapsing Protogiant Elliptical Galaxy at z=3.4 (2008)
Adams, Joshua J, Hill, Gary J., MacQueen, Phillip J.
We have used the visible integral-field replicable unit spectrograph prototype (VIRUS-P), a new integral field spectrograph, to study the spatially and spectrally resolved Lyman-alpha emission line...

Prototype development of the Integral-Field unit for VIRUS (2006)
Kelz, Andreas, Bauer, Svend M., Grupp, Frank, Hill, Gary J., Popow, Emil, Palunas, Povilas, ...
VIRUS is a planned integral-field instrument for the Hobby-Eberly Telescope (HET). In order to achieve a large field-of-view and high grasp at reasonable costs, the approach is to replicate...
Exploring The Frequency Of Close-In Jovian Planets Around M Dwarfs (2006)
Endl, Michael, Cochran, William D., Kuerster, Martin, Paulson, Diane B., Wittenmyer, Robert A., MacQueen, Phillip J., ...
We discuss our high precision radial velocity results of a sample of 90 M dwarfs observed with the Hobby-Eberly Telescope and the Harlan J. Smith 2.7 m Telescope at McDonald Observatory, as well as...
Exploring the frequency of close-in Jovian planets around M dwarfs (2006)
Endl, Michael, Cochran, William D., Kürster, Martin, Paulson, Diane B., Wittenmyer, Robert A., MacQueen, Phillip J., ...
We discuss our high-precision radial velocity results of a sample of 90 M dwarfs observed with the Hobby-Eberly Telescope and the Harlan J. Smith 2.7 m Telescope at McDonald Observatory, as well as...
Convective Wavelength Shifts in the Spectra of Late-Type Stars (2002)
Prieto, Carlos Allende, Lambert, David L., Tull, Robert G., MacQueen, Phillip J.
We present ultra-high resolution spectra for a set of nearby F-G-K stars on, or close to, the main sequence. The wavelength shifts of stellar lines relative to their laboratory wavelengths are...
Schneider, Donald P., Knapp, Gillian R., Hawley, Suzanne L., Covey, Kevin R., Fan, Xiaohui, Ramsey, Lawrence W., ...
Low dispersion optical spectra have been obtained with the Hobby-Eberly Telescope of 22 very red objects found in early imaging data from the Sloan Digital Sky Survey. The objects are assigned...
Schneider, Donald P., Fan, Xiaohui, Strauss, Michael A., Gunn, James E., Richards, Gordon T., Hill, Gary J., ...
We report the discovery of 27 quasars with redshifts between 3.58 and 4.49. The objects were identified as high-redshift candidates based on their colors in Sloan Digital Sky Survey commissioning...
