Investigating the differential limb coupling effect for diffraction-limited spectrographs with PARVI
Andrea S. J. Lin, Ashley D. Baker, Samuel Halverson +5
A promising new architecture for extreme-precision radial velocity (EPRV) spectrographs, hunting for small-amplitude stellar Doppler shifts induced by orbiting planets, is to build…

Redshifted Sodium Transient near Exoplanet Transit
Apurva V. Oza, Julia V. Seidel, H. Jens Hoeijmakers +21
Neutral sodium (Na I) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine…

Fringing analysis and forward modeling of Keck Planet Imager and Characterizer (KPIC) spectra
Katelyn A. Horstman, Jean-Baptiste Ruffio, Jason J. Wang +27
The Keck Planet Imager and Characterizer (KPIC) combines high contrast imaging with high resolution spectroscopy (R~35,000 in K band) to study directly imaged exoplanets and brown…
