The JWST/NIRCam Scattered Light Disks GTO 2780 program: panchromatic coronagraphic imaging of the HD 10647, HD 32297, HD 61005, HD 107146, and HD 181327 debris disk systems
András Gáspár, Jarron M. Leisenring, Schuyler Grace Wolff +13
Debris disks, composed of rocks, boulders, planetesimals, and the dust produced in their collisions, present the most readily observable components of mature planetary systems. The…
Multiband polarimetric imaging of HD 34700 with SCExAO/CHARIS
Minghan Chen, Kellon Lawson, Timothy D. Brandt +5
We present Subaru/SCExAO + CHARIS broadband (JHK) integral field spectroscopy of HD 34700 A in polarized light. CHARIS has the unique ability to obtain polarized integral field ima…
Direct Imaging Discovery and Dynamical Mass of a Substellar Companion Orbiting an Accelerating Hyades Sun-like Star with SCExAO/CHARIS
Masayuki Kuzuhara, Thayne Currie, Takuya Takarada +33
We present the direct-imaging discovery of a substellar companion in orbit around a Sun-like star member of the Hyades open cluster. So far, no other substellar companions have bee…
SCExAO/CHARIS Direct Imaging Discovery of a 20 au Separation, Low-Mass Ratio Brown Dwarf Companion to an Accelerating Sun-like Star
Thayne Currie, Timothy D. Brandt, Masayuki Kuzuhara +27
We present the direct imaging discovery of a substellar companion to the nearby Sun-like star, HD 33632 Aa, at a projected separation of 20 au, obtained with SCExAO/CHARIS i…
Discovery of a Nearby Young Brown Dwarf Disk
M. C. Schutte, K. D. Lawson, J. P. Wisniewski +15
We report the discovery of the youngest brown dwarf with a disk at 102 pc from the Sun, WISEA~J120037.79-784508.3 (W1200-7845), via the Disk Detective citizen science project. We e…
Peter Pan Disks: Long-lived Accretion Disks Around Young M Stars
Steven M. Silverberg, John P. Wisniewski, Marc J. Kuchner +12
WISEA J080822.18-644357.3, an M star in the Carina association, exhibits extreme infrared excess and accretion activity at an age greater than the expected accretion disk lifetime.…
High Fidelity Imaging of the Inner AU Mic Debris Disk: Evidence of Differential Wind Sculpting?
John P. Wisniewski, Adam F. Kowalski, James R. A. Davenport +17
We present new high fidelity optical coronagraphic imagery of the inner 50 au of AU Mic's edge-on debris disk using the BAR5 occulter of the Hubble Space Telescope Imaging Sp…
Identification of Stellar Flares Using Differential Evolution Template Optimization
Kellen D. Lawson, John P. Wisniewski, Eric C. Bellm +2
We explore methods for the identification of stellar flare events in irregularly sampled data of ground-based time domain surveys. In particular, we describe a new technique for id…
