Where's the Weather? Lack of Variability Between Repeated Spitzer Phase Curves of WASP-43 b

Hot Jupiters have cloudy and dynamic atmospheres, which can cause a planet's phase curve to vary from orbit to orbit. However, most hot Jupiter phase curves are only observed once. If the atmosphere is indeed changing, then we're missing something important! In this poster, I present the results of an analysis in which we observed two new phase curves of the hot Jupiter WASP-43 b, in addition to re-analyzing a previously observed phase curve of this planet. We found no variation between these three phase curves, allowing us to place an upper limit on the variability caused by cloud-driven weather
