“…To place further constraints on the secondary component, we observed LHS1610A using the Immersion GRating INfrared Spectrometer (IGRINS; Yuk et al 2010) on the 4.3-meter Discovery Channel Telescope (DCT) in Happy Jack, Arizona, on the nights of UT 2017 September 25 and 26. IGRINS is a cross-dispersed, high-resolution (R=λ/Δλ= 45,000) near-infrared spectrograph with a wavelength coverage of 1.45 to 2.5 μm, which obtains simultaneous observations in both the H and K bands (Yuk et al 2010;Park et al 2014;Mace et al 2016aMace et al , 2016b.…”

We present the spectroscopic orbit of LHS1610A, a newly discovered single-lined spectroscopic binary with a trigonometric distance placing it at 9.9±0.2 pc. We obtained spectra with the TRES instrument on the 1.5 m Tillinghast Reflector at the Fred Lawrence Whipple Observatory located on Mt. Hopkins in AZ. We demonstrate the use of the TiO molecular bands at 7065-7165Åto measure radial velocities and achieve an average estimated velocity uncertainty of 28 m s −1 . We measure the orbital period to be 10.6 days and calculate a minimum mass of 44.8±3.2 M Jup for the secondary, indicating that it is likely a brown dwarf. We place an upper limit to 3σ of 2500 K on the effective temperature of the companion from infrared spectroscopic observations using IGRINS on the 4.3 m Discovery Channel Telescope. In addition, we present a new photometric rotation period of 84.3 days for the primary star using data from the MEarth-South Observatory, with which we show that the system does not eclipse.

“…High-resolution IR spectra now can be obtained with ground based facilities, such as the Very Large Telescope/CRIRES An important H-band high-resolution (R ; 22,500) survey of >10 5 stars in the APOGEE (Majewski et al 2010) 10 experiment is currently underway, with a southern hemisphere extension planned for the near future. The new high-resolution H and K band Immersion Grating Infrared Spectrograph (hereafter IGRINS; Yuk et al 2010) 11 was commissioned in 2014 May at the McDonald Observatory for use with the 2.7 m Smith Telescope. This instrument has been employed for many studies, but early use has concentrated on young stars, the interstellar medium, and various types of emission nebulae.…”

From high resolution (R ; 45,000), high signal-to-noise ratio (S/N > 400) spectra gathered with the Immersion Grating Infrared Spectrograph (IGRINS) in the H and K photometric bands, we have derived elemental abundances of two bright, well-known metal-poor halo stars: the red giant HD 122563 and the subgiant HD 140283. Since these stars have metallicities approaching [Fe/H]=−3, their absorption features are generally very weak. Neutral-species lines of Mg, Si, S and Ca are detectable, as well as those of the light odd-Z elements Na and Al. The derived IR-based abundances agree with those obtained from optical-wavelength spectra. For Mg and Si the abundances from the infrared transitions are improvements to those derived from shorter wavelength data. Many useful OH and CO lines can be detected in the IGRINS HD 122563 spectrum, from which derived O and C abundances are consistent to those obtained from the traditional [O I] and CH features. IGRINS high resolutions Hand K-band spectroscopy offers promising ways to determine more reliable abundances for additional metal-poor stars whose optical features are either not detectable, or too weak, or are based on lines with analytical difficulties.

“…We also took part in NASA's sounding rocket experiment cosmic infrared background experiment (CIBER), an international project to develop IR cameras and spectrometers (Bock et al 2006). Currently, the hyper-spectral infrared spectrometer immersion grating infrared spectrometer (IGRINS) is under development in collaboration with a veteran team of the University of Texas at Austin (Yuk et al 2010). With these experiences, KASI was selected to develop the first space IR camera using Korean technology, which can be extended to many other application fields.…”

6Green Optics Co., Ochang 363-883, KoreaWe have designed and manufactured the Earth observation camera (EOC) of multi-purpose infrared imaging system (MIRIS). MIRIS is a main payload of the STSAT-3, which will be launched in late 2012. The main objective of the EOC is to test the operation of Korean IR technology in space, so we have designed the optical and mechanical system of the EOC to fit the IR detector system. We have assembled the flight model (FM) of EOC and performed environment tests successfully. The EOC is now ready to be integrated into the satellite system waiting for operation in space, as planned.
