Vortex Fiber Nulling for Exoplanet Observations: Implementation and First Light
Daniel Echeverri, Jerry Xuan, Nemanja Jovanovic +31
Vortex fiber nulling (VFN) is a single-aperture interferometric technique for detecting and characterizing exoplanets separated from their host star by less than a diffracted beam…
Dual Purpose Lyot Coronagraph Masks for Simultaneous High-Contrast Imaging and High-Resolution Wavefront Sensing
Garreth Ruane, J. Kent Wallace, A J Eldorado Riggs +8
Directly imaging Earth-sized exoplanets with a visible-light coronagraph instrument on a space telescope will require a system that can achieve raw contrast and main…
Keck/KPIC Emission Spectroscopy of WASP-33b
Luke Finnerty, Tobias Schofield, Ben Sappey +29
We present Keck/KPIC high-resolution () -band thermal emission spectroscopy of the ultra-hot Jupiter WASP-33b. The use of KPIC's single-mode fibers greatly improves…
Onboard Science Instrument Autonomy for the Detection of Microscopy Biosignatures on the Ocean Worlds Life Surveyor
Mark Wronkiewicz, Jake Lee, Lukas Mandrake +10
The quest to find extraterrestrial life is a critical scientific endeavor with civilization-level implications. Icy moons in our solar system are promising targets for exploration…
Detecting exomoons from radial velocity measurements of self-luminous planets: application to observations of HR 7672 B and future prospects
Jean-Baptiste Ruffio, Katelyn Horstman, Dimitri Mawet +36
The detection of satellites around extrasolar planets, so called exomoons, remains a largely unexplored territory. In this work, we study the potential of detecting these elusive o…
