Changes in night sky brightness after a countywide LED retrofit
Li-Wei Hung, Sharolyn J Anderson, Ashley Pipkin +1
The US National Park Service (NPS) Night Skies Program measured changes in sky brightness resulting from a countywide lighting retrofit project. The retrofit took place in Chelan C…
Dune initiation in a bimodal wind regime
Pauline Delorme, Giles. F. S. Wiggs, Matthew. C. Baddock +3
Early-stage bedforms develop into mature dunes through complex interactions between wind, sand transport and surface topography. Depending on varying environmental and wind conditi…
Multiband Polarimetric Imaging of HR 4796A with the Gemini Planet Imager
Pauline Arriaga, Michael P. Fitzgerald, Gaspard Duchêne +49
HR4796A hosts a well-studied debris disk with a long history due to its high fractional luminosity and favorable inclination lending itself well to both unresolved and resolved obs…
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…
The Gemini Planet Imager Exoplanet Survey: Dynamical Mass of the Exoplanet beta Pictoris b from Combined Direct Imaging and Astrometry
Eric L. Nielsen, Robert J. De Rosa, Jason J. Wang +51
We present new observations of the planet beta Pictoris b from 2018 with GPI, the first GPI observations following conjunction. Based on these new measurements, we perform a joint…
Detection of a low-mass stellar companion to the accelerating A2IV star HR 1645
Robert J. De Rosa, Eric L. Nielsen, Julien Rameau +50
The \, Myr A2IV star HR 1645 has one of the most significant low-amplitude accelerations of nearby early-type stars measured from a comparison of the {\it Hipparcos} and {…
