Observed sizes of planet-forming disks trace viscous evolution
L. Trapman, G. Rosotti, A. D. Bosman +2
The evolution of protoplanetary disks is dominated by the conservation of angular momentum, where the accretion of material onto the central star is driven by viscous expansion of…
Constraining the radial drift of millimeter-sized grains in the protoplanetary disks in Lupus
L. Trapman, M. Ansdell, M. R. Hogerheijde +5
Recent ALMA surveys of protoplanetary disks have shown that for most disks the extent of the gas emission is greater than the extent of the thermal emission of the millimeter-sized…
Mass constraints for 15 protoplanetary disks from HD 1-0
M. Kama, L. Trapman, D. Fedele +6
Hydrogen deuteride (HD) rotational line emission can provide reliable protoplanetary disk gas mass measurements, but it is difficult to observe and detections have been limited to…
Gas vs dust sizes of protoplanetary disks: effects of dust evolution
L. Trapman, S. Facchini, M. R. Hogerheijde +2
The extent of the gas in protoplanetary disks is observed to be universally larger than the extent of the dust. This is often attributed to radial drift and grain growth of the mm…
The ALMA Lupus protoplanetary disk survey: evidence for compact gas disks and molecular rings from CN
S. E. van Terwisga, E. F. van Dishoeck, P. Cazzoletti +10
The cyanide radical CN is abundant in protoplanetary disks, with line fluxes often comparable to those of CO. It is known to be sensitive to UV irradiation of the upper disk…
HD far infrared emission as a measure of protoplanetary disk mass
Leon Trapman, Anna Miotello, Mihkel Kama +2
Protoplanetary disks around young stars are the sites of planet formation. While the dust mass can be estimated using standard methods, determining the gas mass - and thus the amou…
