The contents of this repository supplements the publication:

Speedie, J. & Dong, R. (2022). "Testing Velocity Kinks as a Planet Detection Method: Do Velocity Kinks in Surface Gas Emission Trace Planetary Spiral Wakes in the Midplane Continuum?", Astrophysical Journal Letters, 940(2), L43.

Provided are six mp4 files. There is one for each of the following disks/planet candidates:

  1. HD 143006
  2. HD 163296 (Pinte et al. 2020 "#2" kink)
  3. HD 163296 (Izquierdo et al. 2022 "P94" kink)
  4. GW Lup
  5. Sz 129
  6. DoAr 25

Each mp4 file contains 8 frames. Each frame is a figure like Figures 1-4 of Speedie & Dong (2022), where the continuum image has been re-imaged using the DSHARP calibrated measurement set with a different Briggs robust parameter: [-1, -0.5, -0.3, 0, 0.3, 0.5, 1, 2] and no uv-tapering.

The calibrated measurements sets provided by the DSHARP Large Program were sourced from https://almascience.eso.org/almadata/lp/DSHARP/
