- Together with his postdoc, King, Wheatley performed the calculations of energy-limited and hydrodynamic atmospheric escape from the newly-discovered planet LTT9779b. These calculations lead directly to the key conclusions: that the Neptune-sized planet cannot have formed in situ in its current configuration, and it cannot have evolved to its present state through evaporation of a hot Jupiter; hence, the main conclusion that LTT9779b probably evolved though Roche-lobe overflow. Wheatley is also PI of the NGTS project, which contributed precise photometric observations of the transit of LTT9779b.
