TL;DR: In this paper, the Atacama Large Millimeter/submillimeter Array (ALMA) observations from the 2014 Long Baseline Campaign in dust continuum and spectral line emission from the HL Tau region were presented.
Journal ArticleDOI
Flows of gas through a protoplanetary gap

TL;DR: Observations of diffuse CO gas inside the gap, with denser HCO+ gas along gap-crossing filaments are reported, which is sufficient to maintain accretion onto the star at the present rate.
Journal ArticleDOI
Dust and gas in the disk of HL TAURI: surface density, dust settling, and dust-to-gas ratio

TL;DR: In this paper, the authors present a radiative transfer model accounting for the observed gaps and bright rings as well as radial changes of the emissivity index, and find that the dust density is depleted by at least a factor 10 in the main gaps compared to the surrounding rings.

TL;DR: In this paper, the authors used high-resolution and high-sensitivity ALMA observations of the CO(3-2) emission line and the continuum at 850µm, as well as the 3-dimensional radiative transfer code MCFOST to model the data presented in this work.
