Planet Search with the Keck/NIRC2 Vortex Coronagraph in Ms-band for Vega
Bin B. Ren, Nicole L. Wallack, Spencer A. Hurt +12
Gaps in circumstellar disks can signal the existence of planetary perturbers, making such systems preferred targets for direct imaging observations of exoplanets. Being one of the…
Directly Imaging Rocky Planets from the Ground
B. Mazin, É. Artigau, V. Bailey +59
Over the past three decades instruments on the ground and in space have discovered thousands of planets outside the solar system. These observations have given rise to an astonishi…
Planet Formation Imager: Project Update
John D. Monnier, Michael J. Ireland, Stefan Kraus +2
The Planet Formation Imager (PFI) is a near- and mid-infrared interferometer project with the driving science goal of imaging directly the key stages of planet formation, including…
Project 1640 Observations of the White Dwarf HD 114174 B
E. Bacchus, I. R. Parry, R. Oppenheimer +24
We present the first near infra-red spectrum of the faint white dwarf companion HD 114174 B, obtained with Project 1640. Our spectrum, covering the Y, J and H bands, combined with…
Project 1640 Observations of Brown Dwarf GJ 758 B: Near-Infrared Spectrum and Atmospheric Modeling
R. Nilsson, A. Veicht, P. A. Giorla Godfrey +23
The nearby Sun-like star GJ 758 hosts a cold substellar companion, GJ 758 B, at a projected separation of 30 AU, previously detected in high-contrast multi-band photometr…
Reconnaissance of the HR 8799 Exosolar System II: Astrometry and Orbital Motion
L. Pueyo, R. Soummer, J. Hoffmann +30
We present an analysis of the orbital motion of the four sub-stellar objects orbiting HR8799. Our study relies on the published astrometric history of this system augmented with an…
Precision near-infrared radial velocity instrumentation I: Absorption Gas Cells
Peter P. Plavchan, Guillem Anglada-Escude, Russel White +18
We have built and commissioned gas absorption cells for precision spectroscopic radial velocity measurements in the near-infrared in the H and K bands. We describe the construction…
Precision near-infrared radial velocity instrumentation II: Non-Circular Core Fiber Scrambler
Peter P. Plavchan, Michael Bottom, Peter Gao +18
We have built and commissioned a prototype agitated non-circular core fiber scrambler for precision spectroscopic radial velocity measurements in the near-infrared H band. We have…
Reconnaissance of the HR 8799 Exosolar System I: Near IR Spectroscopy
B. R. Oppenheimer, C. Baranec, C. Beichman +29
We obtained spectra, in the wavelength range λ= 995 - 1769 nm, of all four known planets orbiting the star HR 8799. Using the suite of instrumentation known as Project 1640 on the…
Exoplanet Characterization and the Search for Life
J. Kasting, W. Traub, A. Roberge +119
Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmo…
