ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT) V: Sample, overview, and demography of disk molecular emission
Antonio Garufi, Linda Podio, Claudio Codella +9
We present an overview of the ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT), a campaign devoted to the characterization of the molecular emission from partly em…
The TW Hya Rosetta Stone Project III: Resolving the Gaseous Thermal Profile of the Disk
Jenny Calahan, Edwin Bergin, Ke Zhang +16
The thermal structure of protoplanetary disks is a fundamental characteristic of the system that has wide reaching effects on disk evolution and planet formation. In this study, we…
The TW Hya Rosetta Stone Project II: Spatially resolved emission of formaldehyde hints at low-temperature gas-phase formation
Jeroen Terwisscha van Scheltinga, Michiel R. Hogerheijde, L. Ilsedore Cleeves +15
Formaldehyde (HCO) is an important precursor to organics like methanol (CHOH). It is important to understand the conditions that produce HCO and prebiotic molecules dur…
The TW Hya Rosetta Stone Project I: Radial and vertical distributions of DCN and DCO+
Karin I. Oberg, L. Ilsedore Cleeves, Jennifer B. Bergner +16
Molecular D/H ratios are frequently used to probe the chemical past of Solar System volatiles. Yet it is unclear which parts of the Solar Nebula hosted an active deuterium fraction…
Chemical Evolution in a Protoplanetary Disk within Planet Carved Gaps and Dust Rings
Felipe Alarcon, Richard Teague, Ke Zhang +2
Recent surveys of protoplanetary disks show that substructure in dust thermal continuum emission maps is common in protoplanetary disks. These substructures, most prominently rings…
ALMA and VLA Observations of EX Lupi in its Quiescent State
Jacob Aaron White, Á. Kóspál, A. G. Hughes +15
Extreme outbursts in young stars may be a common stage of pre-main-sequence stellar evolution. These outbursts, caused by enhanced accretion and accompanied by increased luminosity…
Visualizing the Kinematics of Planet Formation
Disk Dynamics Collaboration, Philip J. Armitage, Jaehan Bae +23
A stunning range of substructures in the dust of protoplanetary disks is routinely observed across a range of wavelengths. These gaps, rings and spirals are highly indicative of a…
ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT) II: Vertical stratification of CO, CS, CN, HCO, and CHOH in a Class I disk
L. Podio, A. Garufi, C. Codella +8
The chemical composition of planets is inherited from that of the protoplanetary disk at the time of planet formation. Increasing observational evidence suggests that planet format…
Low Level Carbon Monoxide Line Polarization in two Protoplanetary Disks: HD 142527 and IM Lup
Ian W. Stephens, Manuel Fernandez-Lopez, Zhi-Yun Li +2
Magnetic fields are expected to play an important role in accretion processes for circumstellar disks. Measuring the magnetic field morphology is difficult, especially since polari…
Predicting the kinematic evidence of gravitational instability
C. Hall, R. Dong, R. Teague +6
Observations with the Atacama Large Millimeter/Submillimeter array (ALMA) have dramatically improved our understanding of the site of exoplanet formation: protoplanetary discs. How…
The Excitation Conditions of CN in TW Hya
Richard Teague, Ryan Loomis
We report observations of the cyanide anion, CN, in the disk around TW~Hya covering the , and transitions. Using line stacking techniques, 24 hyperfine trans…
Hints of a Population of Solar System Analog Planets from ALMA
Deryl Long, Ke Zhang, Richard Teague +1
The recent ALMA DSHARP survey provided illuminating results on the diversity of substructures in planet forming disks. These substructures trace pebble-sized grains accumulated at…
The efficiency of dust trapping in ringed proto-planetary discs
Giovanni P. Rosotti, Richard Teague, Cornelis Dullemond +2
When imaged at high-resolution, many proto-planetary discs show gaps and rings in their dust sub-mm continuum emission profile. These structures are widely considered to originate…
A Three Dimensional View of Gomez's Hamburger
Richard Teague, Marija R. Jankovic, Thomas J. Haworth +2
Unraveling the 3D physical structure, the temperature and density distribution, of protoplanetary discs is an essential step if we are to confront simulations of embedded planets o…
A multi-frequency ALMA characterization of substructures in the GM Aur protoplanetary disk
Jane Huang, Sean M. Andrews, Cornelis P. Dullemond +12
The protoplanetary disk around the T Tauri star GM Aur was one of the first hypothesized to be in the midst of being cleared out by a forming planet. As a result, GM Aur has had an…
