The PDS 70 system, hosting two planets within its disk, is an ideal target for examining the
effect of planets on dust accumulation, growth, and ongoing planet formation. Here, we …

This paper presents near-infrared spectropolarimetric and velocimetric observations of the
young planet-hosting T Tauri star PDS 70, collected with SPIRou at the 3.6-m Canada …

The grand tack model, more generally called the Masset and Snellgrove mechanism, is a
planetary migration model whereby two giant planets via interactions with their natal disk …

The solar system planetary architecture has been proposed to be consistent with the
terrestrial and giant planets forming from material rings at~ 1 au and~ 5 au, respectively …

Numerous protoplanetary disks exhibit shadows in scattered light observations. These
shadows are typically cast by misaligned inner disks and are associated with observable …

Planets form from interstellar grains of sub-micron to gas giants of thousands of kilometres,
which span over 12 orders of magnitude in size. The prevailing theoretical pathway starts …
