Isochronal age-mass discrepancy of young stars: SCExAO/CHARIS integral field spectroscopy of the HIP 79124 triple system
Ruben Asensio-Torres, Thayne Currie, Markus Janson +24
We present SCExAO/CHARIS 1.1--2.4 micron integral field direct spectroscopy of the young HIP 79124 triple system. HIP 79124 is a member of the Scorpius-Centaurus association, consi…
Multi-epoch Direct Imaging and Time-Variable Scattered Light Morphology of the HD 163296 Protoplanetary Disk
Evan A. Rich, John P. Wisniewski, Thayne Currie +58
We present H-band polarized scattered light imagery and JHK high-contrast spectroscopy of the protoplanetary disk around HD 163296 observed with the HiCIAO and SCExAO/CHARIS instru…
Vortex fiber nulling for exoplanet observations. I. Experimental demonstration in monochromatic light
Daniel Echeverri, Garreth Ruane, Nemanja Jovanovic +2
Vortex fiber nulling is a method for spectroscopically characterizing exoplanets at small angular separations, , from their host star. The starlight is suppressed by c…
Efficient spectroscopy of exoplanets at small angular separations with vortex fiber nulling
Garreth Ruane, Ji Wang, Dimitri Mawet +4
Instrumentation designed to characterize potentially habitable planets may combine adaptive optics and high-resolution spectroscopy techniques to achieve the highest possible sensi…
SCExAO/CHARIS Near-IR High-Contrast Imaging and Integral Field Spectroscopy of the HIP 79977 Debris Disk
Sean Goebel, Thayne Currie, Olivier Guyon +13
We present new, near-infrared (1.1--2.4 ) high-contrast imaging of the bright debris disk surrounding HIP 79977 with the Subaru Coronagraphic Extreme Adaptive Optics system (SC…
SCExAO/CHARIS Near-Infrared Direct Imaging, Spectroscopy, and Forward-Modeling of kappa And b: A Likely Young, Low-Gravity Superjovian Companion
Thayne Currie, Timothy D. Brandt, Taichi Uyama +30
We present SCExAO/CHARIS high-contrast imaging/ integral field spectroscopy of And b, a directly-imaged low-mass companion orbiting a nearby B9V star. We detect And b…
