Uranus in northern midspring: persistent atmospheric temperatures and circulations inferred from thermal imaging

Abstract:

We present results from mid-infrared imaging of Uranus at wavelengths of 13.0 and 18.7 μm, sensing emission from the stratosphere and upper troposphere, acquired using the VISIR instrument at the Very Large Telescope, 2018 September 4–October 20. Using a combination of inverse and forward modeling, we analyze these northern midspring (Ls ~ 46°) images and compare them to archival data to assess seasonal changes since the 1986 southern solstice and subsequent equinox. We find the data are con...
