Mapping Molecular Ion Distributions in a Diverse Sample of Protoplanetary Disks

Deryl E. Long, L. Ilsedore Cleeves, Charles J. Law +10

Observations of ionization-tracing molecules in protoplanetary disks suggest that their ionization environments are diverse due to varying degrees of cosmic ray modulation, stellar…

Measuring the Two-Dimensional Thermal Structures of Protoplanetary Disks

Anna J. Fehr, Sean M. Andrews

We present a flexible, annulus-by-annulus method to constrain the 2-D thermal structure of a protoplanetary disk from optically thick spectral line emission. Using synthetic disk m…

ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk

Joshua B. Lovell, Elliot M. Lynch, Jay Chittidi +6

We present evidence of a negative eccentricity gradient in the debris disk of the nearby A-type main sequence star, Fomalhaut. Fitting to the high-resolution, archival ALMA 1.32 mm…

Detailed Microwave Continuum Spectra from Bright Protoplanetary Disks in Taurus

Caleb Painter, Sean M. Andrews, Claire J. Chandler +9

We present new observations that densely sample the microwave (4-360 GHz) continuum spectra from eight young systems in the Taurus region. Multi-component, empirical model prescrip…

ExoALMA XIII. gas masses from N2H+ and C18O: a comparison of protoplanetary gas disk mass measurement techniques

Leon Trapman, Cristiano Longarini, Giovanni P. Rosotti +37

The gas masses of protoplanetary disks are important but elusive quantities. In this work we present new ALMA observations of N2H+ (3-2) for 11 exoALMA disks. N2H+ is a molecule se…

exoALMA VII: Benchmarking Hydrodynamics and Radiative Transfer Codes

Jaehan Bae, Mario Flock, Andres Izquierdo +25

Forward modeling is often used to interpret substructures observed in protoplanetary disks. To ensure the robustness and consistency of the current forward modeling approach from t…
