JWST-TST High Contrast: Spectroscopic Characterization of the Benchmark Brown Dwarf HD 19467 B with the NIRSpec Integral Field Spectrograph
Kielan K. W. Hoch, Christopher A. Theissen, Travis S. Barman +14
We present the atmospheric characterization of the substellar companion HD 19467 B as part of the pioneering JWST GTO program to obtain moderate resolution spectra (R2,700, 3…
Current laboratory performance of starlight suppression systems, and potential pathways to desired Habitable Worlds Observatory exoplanet science capabilities
Bertrand Mennesson, Ruslan Belikov, Emiel Por +34
We summarize the current best polychromatic (10 to 20 % bandwidth) contrast performance demonstrated in the laboratory by different starlight suppression approaches and systems des…
Stellar Surface Magnetic Fields Impact Limb Darkening
Nadiia M. Kostogryz, Alexander I. Shapiro, Veronika Witzke +8
Stars appear darker at their limbs than at their disk centers because at the limb we are viewing the higher and cooler layers of stellar photospheres. Limb darkening derived from s…
JWST-TST High Contrast: Asymmetries, dust populations and hints of a collision in the Pictoris disk with NIRCam and MIRI
Isabel Rebollido, Christopher C. Stark, Jens Kammerer +21
We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~m provi…
