Robustness of N2H+ as tracer of the CO snowline
Merel L. R. van 't Hoff, Catherine Walsh, Mihkel Kama +2
[Abridged] Snowlines in protoplanetary disks play an important role in planet formation and composition. Since the CO snowline is difficult to observe directly with CO emission, it…
Spirals in protoplanetary disks from photon travel time
M. Kama, P. Pinilla, A. N. Heays
Spiral structures are a common feature in scattered-light images of protoplanetary disks, and of great interest as possible tracers of the presence of planets. However, other mecha…
First detection of gas-phase methanol in a protoplanetary disk
Catherine Walsh, Ryan A. Loomis, Karin I. Oberg +7
The first detection of gas-phase methanol in a protoplanetary disk (TW Hya) is presented. In addition to being one of the largest molecules detected in disks to date, methanol is a…
Determining protoplanetary disk gas masses from CO isotopologues line observations
Anna Miotello, Ewine F. van Dishoeck, Mihkel Kama +1
Despite intensive studies of protoplanetary disks, there is still no reliable way to determine their total mass and their surface density distribution, quantities that are crucial…
Volatile carbon locking and release in protoplanetary disks. A study of TW Hya and HD 100546
M. Kama, S. Bruderer, E. F. van Dishoeck +7
The composition of planetary solids and gases is largely rooted in the processing of volatile elements in protoplanetary disks. To shed light on the key processes, we carry out a c…
Probing the 2D temperature structure of protoplanetary disks with Herschel observations of high-J CO lines
D. Fedele, E. F. van Dishoeck, M. Kama +2
The gas temperature structure of protoplanetary disks is a key ingredient for interpreting various disk observations and for quantifying the subsequent evolution of these systems.…
