A Wide-Field Infrared Camera for the Palomar 200-inch Telescope
- John C. Wilson, S. Eikenberry, T. Stolberg
- PhysicsSPIE Astronomical Telescopes + Instrumentation
- 7 March 2003
The availability of both large aperture telescopes and large format near-infrared (NIR) detectors are making wide-field NIR imaging a reality. We describe the Wide-field Infrared Camera (WIRC), a…
Probing for Exoplanets Hiding in Dusty Debris Disks: Disk Imaging, Characterization, and Exploration with HST/STIS Multi-Roll Coronagraphy
- G. Schneider, C. Grady, T. Rodigas
- Physics, Geology
- 27 June 2014
Spatially resolved scattered-light images of circumstellar (CS) debris in exoplanetary systems constrain the physical properties and orbits of the dust particles in these systems. They also inform on…
Discovery of Small-Scale Spiral Structures in the Disk of SAO 206462 (HD 135344B): Implications for the Physical State of the Disk from Spiral Density Wave Theory
We present high-resolution, H-band imaging observations, collected with Subaru/HiCIAO, of the scattered light from the transitional disk around SAO 206462 (HD 135344B). Although previous sub-mm…
Images of the Extended Outer Regions of the Debris Ring Around HR 4796 A
- C. Thalmann, M. Janson, Sendai
- Physics, Geology
- 11 October 2011
We present high-contrast images of HR 4796 A taken with Subaru/HiCIAO in the H band, resolving the debris disk in scattered light. The application of specialized angular differential imaging methods…
DIRECT IMAGING OF A COLD JOVIAN EXOPLANET IN ORBIT AROUND THE SUN-LIKE STAR GJ 504
- M. Kuzuhara, M. Tamura, T. Usuda
- Physics, Geology
- 10 July 2013
Several exoplanets have recently been imaged at wide separations of >10?AU from their parent stars. These span a limited range of ages ( 0.5?mag), implying thick cloud covers. Furthermore,…
Direct Imaging of Fine Structures in Giant Planet Forming Regions of the Protoplanetary Disk around AB Aurigae
- J. Hashimoto, M. Tamura, T. Usuda
- Physics, Geology
- 22 February 2011
We report high-resolution 1.6 μm polarized intensity (PI) images of the circumstellar disk around the Herbig Ae star AB Aur at a radial distance of 22 AU (015) up to 554 AU (385), which have been…
Infrared Non-detection of Fomalhaut b: Implications for the Planet Interpretation
- M. Janson, J. Carson, D. Lafrenière, D. Spiegel, J. Bent, P. Wong
- Physics, Geology
- 20 January 2012
The nearby A4-type star Fomalhaut hosts a debris belt in the form of an eccentric ring, which is thought to be caused by dynamical influence from a giant planet companion. In 2008, a detection of a…
Coldest Imaged Companion of a Sun-Like Star
- C. Thalmann, J. Carson, U. Hawaii
- Physics, Geology
- 5 November 2009
We present the discovery of a brown dwarf or possible planet at a projected separation of 19 = 29 AU around the star GJ 758, placing it between the separations at which substellar companions are…
A statistical analysis of seeds and other high-contrast exoplanet surveys: Massive planets or low-mass brown dwarfs?
- Timothy D. Brandt, M. McElwain, M. Tamura
- Physics, Geology
- 21 April 2014
We conduct a statistical analysis of a combined sample of direct imaging data, totalling nearly 250 stars. The stars cover a wide range of ages and spectral types, and include five detections (κ And…
DIRECT IMAGING DISCOVERY OF A “SUPER-JUPITER” AROUND THE LATE B-TYPE STAR κ And*
- J. Carson, C. Thalmann, M. Tamura
- Physics, Geology
- 15 November 2012
We present the direct imaging discovery of an extrasolar planet, or possible low-mass brown dwarf, at a projected separation of 55 ± 2 AU (1.''058 ± 0.''007) from the B9-type star κ And. The planet…
