Linear Polarization Variations and Circular Polarization are Common Among Airless Bodies

Sloane J. Wiktorowicz, Amanda J. Bayless, Larissa A. Nofi

Using the POLISH2 polarimeter at the Lick Observatory Shane 3-m and Nickel 1-m telescopes, we discover rotation phase-locked variations in linear polarization to be common among as…

A Scatter of Light from a Polarized World

Sloane J. Wiktorowicz, Pushkar Kopparla, Jiazheng Li +1

Many known exoplanets harbor clouds, which lead to degeneracies in spectroscopic models between particle composition and size. Polarimetry, however, provides independent assessment…

Testing the Interaction Between a Substellar Companion and a Debris Disk in the HR 2562 System

Stella Yimiao Zhang, Gaspard Duchêne, Robert J. De Rosa +51

The HR 2562 system is a rare case where a brown dwarf companion resides in a cleared inner hole of a debris disk, offering invaluable opportunities to study the dynamical interacti…

A Decade of Linear and Circular Polarimetry with the POLISH2 Polarimeter

Sloane J. Wiktorowicz, Agnieszka Słowikowska, Larissa A. Nofi +15

The POLISH2 optical polarimeter has been in operation at the Lick Observatory 3-m Shane telescope since 2011, and it was commissioned at the Gemini North 8-m in 2016. This instrume…

HD 165054: an astrometric calibration field for high-contrast imagers in Baade's Window

Meiji M. Nguyen, Robert J. De Rosa, Jason J. Wang +51

We present a study of the HD 165054 astrometric calibration field that has been periodically observed with the Gemini Planet Imager. HD 165054 is a bright star within Baade's Windo…
