Infrared Spectroscopy of Symbiotic Stars. I. Orbits for Well-Known S-Type Systems
First results are reported for a program of monitoring symbiotic-star velocities in the 1.6 μm region with infrared-array technology. Infrared radial velocities have been used to determineExpand
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-spaceExpand
Design of the Gemini near-infrared spectrograph
The Gemini Near-Infrared Spectrograph (GNIRS) supports a variety of observing modes over the 1-5 μm wavelength region, matched to the infrared-optimized performance of the Gemini 8-m telescopes. WeExpand
The Phoenix spectrograph at Gemini South
Phoenix, a high resolution near-infrared spectrograph build by NOAO, was first used on the Gemini South telescope in December 2001. Previously on the Kitt Peak 2.1 and 4 meter telescopes, PhoenixExpand
Infrared Spectroscopy of Symbiotic Stars. IV. V2116 Ophiuchi/GX 1+4, The Neutron Star Symbiotic
We have computed, using 17 infrared radial velocities, the first set of orbital elements for the M giant in the symbiotic binary V2116 Ophiuchi. The giant's companion is a neutron star, the brightExpand
A flux-limited sample of Galactic carbon stars
Published observational data (including IRAS observations) for a flux-limited sample of 215 Galactic carbon stars (CSs) selected from the 2-micron sky survey of Neugebauer and Leighton (1969) areExpand
Phoenix: a cryogenic high-resolution 1- to 5-μm infrared spectrograph
We describe a cryogenic, high-resolution spectrograph (Phoenix) for the 1-5 micrometers region. Phoenix is an echelle spectrograph of the near-Littrow over-under configuration without crossExpand
We present near-infrared light curves of supernova (SN) 2011fe in M101, including 34 epochs in H band starting 14 days before maximum brightness in the B band. The light curve data were obtained withExpand
Effective temperatures of late-type stars : the field giants from K0 to M6.
Angular diameters from lunar occultation are combined with infrared photometry to determine effective temperatures, T/sub eff/, for K0--M6 giants. The relation between T/sub eff/ and colorExpand
