We investigate the interaction of gas and dust in a protoplanetary disk in the presence of a massive planet using a new two-fluid hydrodynamics code. In view of future observations of planet-forming disks we focus on the condition for gap formation in the dust fluid. While only planets more massive than 1 Jupiter mass (${{M}_{\rm J}}$) open up a gap in the gas disk, we find that a planet of 0.1 ${{M}_{\rm J}}$ already creates a gap in the dust disk. This makes it easier to find lower-mass planets orbiting in their protoplanetary disk if there is a significant population of mm-sized particles.

Dust flow in gas disks in the presence of embedded planets (2006, background): “Again, as in Paardekooper & Mellema (2004), we see a clear gap and a density enhancement at the position of the 2:1 mean motion resonance.”
Dust Evolution and the Formation of Planetesimals (2016, result): “Such vortices can trap dust particles (e.g., Barge & Sommeria 1995; Meheut et al. 2012; Lyra & Lin 2013; Raettig et al. 2015) in a similar way to pressure bumps (Paardekooper & Mellema 2004; Pinilla et al. 2012; Zhu et al. 2012; Birnstiel et al. 2013; Lyra & Lin 2013).”
UNVEILING THE STRUCTURE OF PRE-TRANSITIONAL DISKS (2010, background): “Theories predict that newly forming planets should clear the material around themselves through tidal disturbances leaving behind disk gaps (Goldreich & Tremaine 1980; Ward 1988; Rice et al. 2003; Paardekooper & Mellema 2004; Quillen et al. 2004; Varnière et al. 2006).”

Dust dynamics during protoplanetary disc clearing (2007, result): “…by the same physical process (a reversal in the direction of the pressure gradient close to the disc edge), have been found by other authors (e.g. Paardekooper & Mellema 2004, 2006), so although we are unable to make detailed predictions we are satisfied that the formation of the dust-rich ring…”
Gravoturbulent Formation of Planetesimals (2005, background): “The same mechanism can drain millimeter-sized dust grains from the underdense regions around a protoplanet that is not massive enough to open a gap in the gaseous component of the disc (Paardekooper & Mellema 2004).”

The Disk Substructures at High Angular Resolution Project (DSHARP). II. Characteristics of Annular Substructures (2018, background): “Planets The most popular hypothesis for the origin of annular substructures in disks is that they result from gravitational interactions between the disk and one or more planets (e.g., Papaloizou & Lin 1984; Paardekooper & Mellema 2004; Fouchet et al. 2010).”
Multiple Disk Gaps and Rings Generated by a Single Super-Earth (2017, methodology): “Note that our 10M⊕ planet is not massive enough to trap dust effectively at its 2:1 resonance at r = 1.6rp, by contrast to the higher mass planet considered by Paardekooper & Mellema (2004, 2006).”
Dust filtration at gap edges: Implications for the spectral energy distributions of discs with embedded planets (2006, background): “This could occur in the presence of self-gravitating spiral structures (Haghighipour & Boss 2003; Rice et al. 2004), in the presence of vortices (Klahr & Bodenheimer 2003), or if an embedded planet has opened a gap in the disc (Paardekooper & Mellema 2004, 2006).”
Standing on the shoulders of giants : Trojan Earths and vortex trapping in low mass self-gravitating protoplanetary disks of gas and solids (2008, background): “Paardekooper & Mellema (2004) studied the dynamics of dust in a gaseous disk, finding that even low mass planets carve a deep dust gap.”
DUST AND GAS IN THE DISK OF HL TAURI: SURFACE DENSITY, DUST SETTLING, AND DUST-TO-GAS RATIO (2015, background): “nd detailed hydrodynamical simulations of gas+dust systems are required to determine the mass of any planet responsible for such gaps. Numerical predictions suggest that a planetary core between 30M (Paardekooper and Mellema 2004) and 150 M (Fouchet et al. 2010) could produce such a decrement in the”
