Protoplanetary disk masses in NGC 2024: Evidence for two populations
Sierk E. van Terwisga, Ewine F. van Dishoeck, Rita K. Mann +8
Protoplanetary disks in dense, massive star-forming regions are strongly affected by their environment. How this environmental impact changes over time is an important constraint o…
The Formation of Stars -- From Filaments to Cores to Protostars and Protoplanetry Disks
James Di Francesco, Helen Kirk, Doug Johnstone +16
Star formation involves the flow of gas and dust within molecular clouds into protostars and young stellar objects (YSOs) due to gravity. Along the way, these flows are shaped sign…
Bright C2H emission in protoplanetary disks in Lupus: high volatile C/O>1 ratios
A. Miotello, S. Facchini, E. F. van Dishoeck +6
ALMA surveys have shown that CO emission in protoplanetary disks is much fainter than expected. Accordingly, CO-based gas masses and gas/dust ratios are orders of magnitude lower t…
New Spatially Resolved Imaging of the SR 21 Transition Disk and Constraints on the Small-Grain Disk Geometry
Steph Sallum, Andy Skemer, Josh Eisner +9
We present new 0.6 - 4 m imaging of the SR 21 transition disk from Keck/NIRC2 and Magellan/MagAO. The protoplanetary disk around SR 21 has a large (~ 30 - 40 AU) clearing first…
High gas/dust size ratio indicating efficient radial drift in the mm-faint CX Tau disk
S. Facchini, E. F. van Dishoeck, C. F. Manara +7
The large majority of protoplanetary disks have very compact (AU) continuum emission at mm wavelengths. However, high angular resolution observations that resolve the…
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…
