HD 91669b: A New Brown Dwarf Candidate from the McDonald Observatory Planet Search
Robert A. Wittenmyer, Michael Endl, William D. Cochran +4
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…
B2 0902+34: A Collapsing Protogiant Elliptical Galaxy at z=3.4
Joshua J Adams, Gary J. Hill, Phillip J. MacQueen
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-al…
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX): Description and Early Pilot Survey Results
G. J. Hill, K. Gebhardt, E. Komatsu +11
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) will outfit the 10 m HET with a new wide field and an array of 150 integral-field spectrographs to survey a 420 sq. deg.…
Prototype development of the Integral-Field unit for VIRUS
Andreas Kelz, Svend M. Bauer, Frank Grupp +6
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…
Exploring The Frequency Of Close-In Jovian Planets Around M Dwarfs
Michael Endl, William D. Cochran, Martin Kuerster +4
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 Observ…
A Dedicated M-Dwarf Planet Search Using The Hobby-Eberly Telescope
M. Endl, W. D. Cochran, R. G. Tull +1
We present first results of our planet search program using the 9.2 meter Hobby-Eberly Telescope (HET) at McDonald Observatory to detect planets around M-type dwarf stars via high-…
Convective Wavelength Shifts in the Spectra of Late-Type Stars
Carlos Allende Prieto, David L. Lambert, Robert G. Tull +1
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 wav…
L Dwarfs Found in Sloan Digital Sky Survey Commissioning Data II. Hobby-Eberly Telescope Observations
Donald P. Schneider, Gillian R. Knapp, Suzanne L. Hawley +21
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…
Observations of Faint, Hard-Band X-ray Sources in the Field of CRSS J0030.5+2618 with the Chandra X-ray Observatory and the Hobby-Eberly Telescope
W. N. Brandt, A. E. Hornschemeier, D. P. Schneider +9
We present results from a study of 2-8 keV X-ray sources detected by the Advanced CCD Imaging Spectrometer (ACIS) instrument on the Chandra X-ray Observatory in the field of the z=…
The Low Resolution Spectrograph of the Hobby-Eberly Telescope II. Observations of Quasar Candidates from the Sloan Digital Sky Survey
D. P. Schneider, Gary J. Hill, X. Fan +1
This paper describes spectra of quasar candidates acquired during the commissioning phase of the Low-Resolution Spectrograph of the Hobby-Eberly Telescope. The objects were identif…
