A Characterization of JWST MIRI Detector Persistence and Implications for High-Contrast Imaging
Alisha Vasan, Mary Anne Limbach, Andrew Vanderburg +2
The JWST MIRI detector exhibits a flux deficit persistence, but its timescales and impacts remain largely uncharacterized, particularly at the longest imaging wavelengths. In this…
An on-sky investigation into factors limiting the performance of Keck-NIRC2 for conducting infrared high-contrast imaging
Rachel Bowens-Rubin, Maïssa Salama, Jayke S. Nguyen +2
The most common instrument used by the exoplanet/brown dwarf direct imaging community at the W.M. Keck Observatory is currently the NIRC2 near-infrared imager. We performed on-sky…
On the Detection of Exorings in Reflected Light with JWST NIRCam
Rachel Bowens-Rubin, Mary Anne Limbach, Sam Hopper +4
When directly imaging a cold giant exoplanet hosting a ring system, the reflected light from the rings can outshine the planet's thermal emission and reflected-light in the near-in…
Follow-Up Exploration of the TWA 7 Planet-Disk System with JWST NIRCam
Katie A. Crotts, Aarynn L. Carter, Kellen Lawson +39
The young M-star TWA 7 hosts a bright and near face-on debris disk, which has been imaged from the optical to the submillimeter. The disk displays multiple complex substructures su…
NIRCam yells at cloud: JWST MIRI imaging can directly detect exoplanets of the same temperature, mass, age, and orbital separation as Saturn and Jupiter
Rachel Bowens-Rubin, James Mang, Mary Anne Limbach +9
NIRCam and MIRI coronagraphy have successfully demonstrated the ability to directly image young sub-Jupiter mass and mature gas-giant exoplanets. However, these modes struggle to r…
Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534b
Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald +12
We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with…
