Betelgeuse scope: Single-mode-fibers-assisted optical interferometer design for dedicated stellar activity monitoring
Narsireddy Anugu, Katie M. Morzinski, Josh Eisner +12
Betelgeuse has gone through a sudden shift in its brightness and dimmed mysteriously. This is likely caused by a hot blob of plasma ejected from Betelgeuse and then cooled to obscu…
The Wide Integral Field Infrared Spectrograph: Commissioning Results and On-sky Performance
Suresh Sivanandam, Dae-Sik Moon, R. Elliot Meyer +11
We have recently commissioned a novel infrared ( m) integral field spectrograph (IFS) called the Wide Integral Field Infrared Spectrograph (WIFIS). WIFIS is a unique in…
iLocater: A Diffraction-limited Doppler Spectrometer for the Large Binocular Telescope
Justin R. Crepp, Jonathan Crass, David King +31
We are developing a stable and precise spectrograph for the Large Binocular Telescope (LBT) named "iLocater." The instrument comprises three principal components: a cross-dispersed…
High contrast imaging at the LBT: the LEECH exoplanet imaging survey
Andrew J. Skemer, Philip Hinz, Simone Esposito +34
In Spring 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its 130-night campaign from the Large Binocular Telescope (LBT) atop Mt Graham, Arizona. This surv…
Simultaneous Exoplanet Characterization and deep wide-field imaging with a diffractive pupil telescope
Olivier Guyon, Josh A. Eisner, Roger Angel +12
High-precision astrometry can identify exoplanets and measure their orbits and masses, while coronagraphic imaging enables detailed characterization of their physical properties an…
High precision astrometry with a diffractive pupil telescope
Olivier Guyon, Eduardo A. Bendek, Thomas D. Milster +11
Astrometric detection and mass determination of Earth-mass exoplanets requires sub-microarcsec accuracy, which is theoretically possible with an imaging space telescope using field…
