1029. JWST as a New Voyager for the Giant Planets

Leigh Fletcher (University of Leicester)

Plenary Talk

The first three years of JWST scientific operations have provided a treasure trove of new discoveries in our Solar System. Not since Voyager’s Grand Tour have we had a facility capable of spatially-resolved infrared spectroscopy of the four giant planet systems with shared techniques and instrumentation, enabling a comprehensive comparative planetology of the gas and ice giants, their rings,...

1028. The environmental dependence of star and planet formation over cosmic time

Steven Longmore (Liverpool John Moores University)

Plenary Talk

Observations of star forming regions in the solar neighbourhood provide the empirical foundation for our current understanding of star and planet formation. In this paradigm, gas is converted into stellar systems in an environmentally independent process which can be described by “universal” dense-gas-star-formation relations. The resulting stellar systems form in isolation, and there is...
