Shadows cast by precessing annuli as evidence for an inclined planet in HD 139614
Katie L. Milsom, Tim J. Harries, Evan A. Rich +3
We analyse scattered-light images at multiple epochs of the protoplanetary disc HD139614 taken with GPI and SPHERE instruments. We show that the azimuthal distribution of the surfa…

Scattered light signatures of flyby-induced warps in protoplanetary discs
Katie L. Milsom, Tim J. Harries, C. J. Nixon
We explore the observational signatures of flybys in scattered light images of protostellar discs. The warps are modelled using 1D warp propagation theory coupled to a fast radiati…
