CO and dust properties in the TW Hya disk from high-resolution ALMA observations
Jane Huang, Sean M. Andrews, L. Ilsedore Cleeves +10
We analyze high angular resolution ALMA observations of the TW Hya disk to place constraints on the CO and dust properties. We present new, sensitive observations of the CO…
Variable HCO Emission in the IM Lup Disk: X-ray Driven Time-Dependent Chemistry?
L. Ilsedore Cleeves, Edwin A. Bergin, Karin I. Öberg +3
We report the first detection of a substantial brightening event in an isotopologue of a key molecular ion, HCO, within a protoplanetary disk of a T Tauri star. The HCO$…
Mass inventory of the giant-planet formation zone in a solar nebula analog
Ke Zhang, Edwin A. Bergin, Geoffrey A. Blake +2
The initial mass distribution in the solar nebula is a critical input to planet formation models that seek to reproduce today's Solar System. Traditionally, constraints on the gas…
The Radial Distribution of H2 and CO in TW Hya as Revealed by Resolved ALMA Observations of CO Isotopologues
Kamber R. Schwarz, Edwin A. Bergin, L. Ilsedore Cleeves +5
CO is widely used as a tracer of molecular gas. However, there is now mounting evidence that gas phase carbon is depleted in the disk around TW Hya. Previous efforts to quantify th…
Indirect Detection of Forming Protoplanets via Chemical Asymmetries in Disks
L. Ilsedore Cleeves, Edwin A. Bergin, Tim J. Harries
We examine changes in the molecular abundances resulting from increased heating due to a self-luminous planetary companion embedded within a narrow circumstellar disk gap. Using 3D…
Evidence for DCO+ as a probe of ionization in the warm disk surface
Cécile Favre, Edwin A. Bergin, L. Ilsedore Cleeves +3
In this Letter we model the chemistry of DCO in protoplanetary disks. We find that the overall distribution of the DCO abundance is qualitatively similar to that of CO…
