An archival summary: 15 years of ALMA observations on disks and planet formation
Nicolas T. Kurtovic, Lizxandra Flores-Rivera, Laura M. Perez +15
The Atacama Large (sub-)millimeter Array (ALMA) has been in scientific operations for almost 15 years. We celebrate this achievement by providing a summary of the ``Disks and plane…
Molecules with ALMA at Planet-forming Scales (MAPS) V: CO gas distributions
Ke Zhang, Alice S. Booth, Charles J. Law +32
Here we present high resolution (15-24 au) observations of CO isotopologue lines from the Molecules with ALMA on Planet-forming Scales (MAPS) ALMA Large Program. Our analysis emplo…
Molecules with ALMA at Planet-forming Scales (MAPS) VIII: CO Gap in AS 209--Gas Depletion or Chemical Processing?
Felipe Alarcón, Arthur Bosman, Edwin Bergin +22
Emission substructures in gas and dust are common in protoplanetary disks. Such substructures can be linked to planet formation or planets themselves. We explore the observed gas s…
Molecules with ALMA at Planet-forming Scales (MAPS). XV. Tracing protoplanetary disk structure within 20 au
Arthur D. Bosman, Edwin A. Bergin, Ryan A. Loomis +25
Constraining the distribution of gas and dust in the inner 20 au of protoplanetary disks is difficult. At the same time, this region is thought to be responsible for most planet fo…
Molecules with ALMA at Planet-forming Scales (MAPS). VII. Sub-stellar O/H and C/H and super-stellar C/O in planet feeding gas
Arthur D. Bosman, Felipe Alarcón, Edwin A. Bergin +28
The elemental composition of the gas and dust in a protoplanetary disk influences the compositions of the planets that form in it. We use the Molecules with ALMA at Planet-forming…
Molecules with ALMA at Planet-forming Scales (MAPS) VI: Distribution of the small organics HCN, C2H, and H2CO
Viviana V. Guzmán, Jennifer B. Bergner, Charles J. Law +22
Small organic molecules, such as C2H, HCN, and H2CO, are tracers of the C, N, and O budget in protoplanetary disks. We present high angular resolution (10-50 au) observations of C2…
