This page shows some of the scientific highlights from SCExAO. Some of the figures have been published and others have not. Please contact us for more information.


HiCIAO

HD36546 Near-IR scattered light discovery of a bright debris disk around HD 36546 with SCExAO/HiCIAO and the vector vortex coronagraph. The disk appears nearly edge on and surrounds an extremely young stars (~5—10 Myr). (Currie, Guyon, & Tamura et al. 2017)

kappaAndVortex Detection of kappa And b with SCExAO/HiCIAO using the vector vortex coronagraph (Kuhn, Serabyn, & Lozi et al. 2018)



CHARIS: Self-luminous planets

SP
Left: Focal-plane image of SCExAO + the shaped-pupil coronagraph after precise optical alignment. Right: Detection of HR 8799 cde with SCExAO/CHARIS using the shaped-pupil obtained in fair conditions: all three planets are easily visible. (Currie, Kasdin, & Groff 2018)

HR8799 Data for HR 8799 reveal planets cde at extremely high SNR even without aggressive SDI, yielding high-quality JHK spectra.

kappaAnd The low-mass companion kappa And b is easily visible in raw CHARIS data and detected at SNR > 175 in 14 minutes of integration time. Its spectrum may provide new constraints on its gravity (and, in turn, its mass).

CHARIS: Disks

HD32297 CHARIS data for HD 32297 reveal the disk down to ~0.1”—0.15” in a few minutes of integration time.
(Data reduction performed by T. Currie)

CHARIS data for another debris disk provides some evidence for a hitherto unseen brightness asymmetry. Spatially-resolved spectra available with CHARIS can constrain the dust composition of these and other debris disks.

VAMPIRES
