WInDI: a Warp-Induced Dust Instability in protoplanetary discs
Hossam Aly, Rebecca Nealon, Jean-François Gonzalez
We identify a new dust instability that occurs in warped discs. The instability is caused by the oscillatory gas motions induced by the warp in the bending wave regime. We first de…
Formation of misaligned second-generation discs through flyby encounters
Jeremy L. Smallwood, Rebecca Nealon, Nicolás Cuello +2
Observations reveal protoplanetary discs being perturbed by flyby candidates. We simulate a scenario where an unbound perturber, i.e., a flyby, undergoes an inclined grazing encoun…
The surprising evolution of the shadow on the TW Hya disk
J. Debes, R. Nealon, R. Alexander +8
We report new total intensity visible light high contrast imaging of the TW Hya disk taken with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST).…
