Stellar occultation of HIP 54057 by Jupiter and Ganymede

Results (15/04/2015): Announcement (13/12/2015): The structure and variability of the upper atmospheres of the giant planets may be investigated by occultation techniques [1]. Ground-based photometric monitoring of stellar occultations measure the attenuation of starlight by the planet’s intervening atmosphere due to differential refraction. This requires a sufficiently bright star to act…
