PI: Dr. Lifan Wang Texas A & M University Y CoI: Prof. Alex V. Filippenko University of California - Berkeley N CoI: Ping Yang Texas A & M University N ------------------------------------------------------------------------------------ Abstract We propose to use the ACS/WFC polarimetric mode on HST to obtain the first high-SNR, multi-wavelength polarization maps of Jupiter's entire disk in four SDSS filters (g, r, i, z) at a resolution more than five times higher than any prior measurements. These observations will enable us to: (1) retrieve aerosol phase functions and vertical layering across belts, zones, and the Great Red Spot; (2) detect the predicted transition from positive to negative polarization at intermediate latitudes; (3) quantify the spatial variability of the polar stratospheric haze, which is linked to auroral chemistry and magnetospheric activity; and (4) separate stratospheric and tropospheric aerosol contributions. The polar regions exhibit strong radial polarization (up to 11.5%) due to unique aggregate particles; our maps will resolve polar haze structure at ~1400 km scales and track temporal variability. The data will be directly coordinated with Juno's perijove passes in February 2027, linking in situ plasma and auroral measurements to haze distribution. Furthermore, Jupiter serves as the nearest giant-planet analog for exoplanets; our polarization maps provide a critical empirical benchmark for interpreting unresolved exoplanet polarimetry. Deliverables include fully calibrated cylindrical maps of Stokes I, Q, U, polarization degree and angle, a catalog of feature properties, and open-source radiative transfer models. This program maximizes HST's unique polarimetric capability and leaves a lasting legacy for planetary and exoplanet science. ------------------------------------------------------------------------------------ Observations Description ------------------------ We propose to observe Jupiter in ACS/WFC Imaging polarimetry mode. All four filters have calibration data taken as part of an ACS program to calibrate the polarizer/filter combination to 1% or better. We require no dither due to short exposure times and long readout. We require all six orbits of observations to be carried out consecutively to cover the whole rotation period of Jupiter of ~9.9 hours. Each set of 3 exposures at the same filter but 3 different polarizers has been grouped into a sequence. Due to short exposure time, the ACS readout buffer needs to be dumped between integrations. Ideally, we would like to read out after each set of 3 exposures was obtained, which minimizes the rotation of Jupiter during the exposures between different polarizers. 18355( 3) - 22-Sep-2026 05:02:26 - [ 2] Because instrumental polarization is highly dependent on the rolling angle of the spacecraft, i.e., the `PA_V3', we would prefer to adopt a rolling angle that is identical to that used in the calibration program 13964, namely PA_V3 = 239.06 deg. ------------------------------------------------------------------------------------ 18355( 3) -
