Bowshocks driven by the pole-on molecular jet of outbursting protostar SVS 13
G. Blázquez-Calero, G. Anglada, S. Cabrit +13
Outflows play a key role in the star and planet formation processes. Some outflows show discrete clumps of cold molecular gas moving at extremely high velocities (EHVs) of 10…
Resolving the large exoKuiper belt of the HD 126062 debris disc and extended gas emission in its vicinity
James M. Miley, Grant M. Kennedy, Alvaro Ribas +8
Intermediate-mass stars (1-3 Msun) host some of the brightest and best-studied debris discs. This stellar class is also the most frequent host of molecular gas in systems older tha…
A young gas giant and hidden substructures in a protoplanetary disk
Álvaro Ribas, Miguel Vioque, Francesco Zagaria +7
The detection of planets in protoplanetary disks has proven to be extremely challenging. In contrast, rings and gaps, usually attributed to planet-disk interactions, have been foun…
Radio multiwavelength analysis of the compact disk CX Tau: Presence of strong free-free variability or anomalous microwave emission
Pietro Curone, Leonardo Testi, Enrique Macias +8
Protoplanetary disks emit radiation across a broad range of wavelengths, requiring a multiwavelength approach to fully understand their physical mechanisms and how they form planet…
Tracing snowlines and C/O ratio in a planet-hosting disk: ALMA molecular line observations towards the HD169142 disk
Alice S. Booth, Charles J. Law, Milou Temmink +2
The composition of a forming planet is set by the material it accretes from its parent protoplanetary disk. Therefore, it is crucial to map the chemical make-up of the gas in disks…
Porous Dust Particles in Protoplanetary Disks: Application to the HL Tau Disk
Shangjia Zhang, Zhaohuan Zhu, Takahiro Ueda +4
Dust particle sizes constrained from dust continuum and polarization observations by radio interferometry are inconsistent by at least an order of magnitude. Motivated by porous du…
Measuring the Dust Masses of Protoplanetary Disks in Lupus with ALMA: Evidence that Disks can be Optically Thick at 3 mm
Z. Xin, C. C. Espaillat, A. M. Rilinger +2
Accurate disk mass measurements are necessary to constrain disk evolution and the timescale of planet formation, but such measurements are difficult to make and are very dependent…
Determining Dust Properties in Protoplanetary Disks: SED-derived Masses and Settling With ALMA
Anneliese Rilinger, Catherine Espaillat, Zihua Xin +3
We present spectral energy distribution (SED) modeling of 338 disks around T Tauri stars from eleven star-forming regions, ranging from 0.5 to 10 Myr old. The disk masses we…
Update on the Systematics in the ALMA Proposal Review Process after Cycle 8
John M. Carpenter, Andrea Corvillon, Jennifer Donovan Meyer +4
We present an updated analysis of systematics in the Atacama Large Millimeter/submillimeter Array (ALMA) proposal ranks from Carpenter (2020) to include the last two ALMA cycles, w…
Testing the Potential for Radio Variability in Disks around T Tauri Stars with Observations and Chemical Modeling
C. C. Espaillat, E. Macias, J. Wendeborn +5
A multiwavelength observing campaign of the T Tauri star (TTS) GM Aur was undertaken in 2019 December that obtained Swift X-ray and NUV fluxes, HST NUV spectra, LCOGT ugri and TESS…
Molecules with ALMA at Planet-forming Scales. XX. The Massive Disk Around GM Aurigae
Kamber R. Schwarz, Jenny K. Calahan, Ke Zhang +25
Gas mass remains one of the most difficult protoplanetary disk properties to constrain. With much of the protoplanetary disk too cold for the main gas constituent, H2, to emit, alt…
Characterizing the dust content of disk substructures in TW Hya
Enrique Macias, Osmar Guerra-Alvarado, Carlos Carrasco-Gonzalez +4
We present Atacama Large Millimeter Array (ALMA) observations of TW Hya at 3.1 mm with milliarcsecond resolution. These new data were combined with archival high angular r…
Modeling protoplanetary disk SEDs with artificial neural networks: Revisiting the viscous disk model and updated disk masses
Á. Ribas, C. C. Espaillat, E. Macías +1
We model the spectral energy distributions (SEDs) of 23 protoplanetary disks in the Taurus-Auriga star-forming region using detailed disk models and a Bayesian approach. This is ma…
A Study of Millimeter Variability in FUor Objects
John Wendeborn, Catherine C. Espaillat, Enrique Macias +6
FU Orionis objects (FUors) are rapidly-accreting, pre-main sequence objects that are known to exhibit large outbursts at optical and near-infrared wavelengths, with post-eruption,…
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…
Modeling the accretion disk around the high-mass protostar GGD 27-MM1
N. Añez-Lopez, M. Osorio, G. Busquet +9
Recent high-angular resolution (40 mas) ALMA observations at 1.14 mm resolve a compact (R~200 au) flattened dust structure perpendicular to the HH 80-81 jet emanating from the GGD…

Enrique Macias, Catherine Espaillat, Mayra Osorio +10
We present a detailed multi-wavelength characterization of the multi-ring disk of HD 169142. We report new ALMA observations at 3 mm and analyze them together with archival 0.89 an…
Science with an ngVLA: Resolved Substructures in Protoplanetary Disks
Sean M. Andrews, David J. Wilner, Enrique Macias +2
Terrestrial planets and the cores of giant planets are thought to be built by the collisional agglomeration of solids spanning over 20 orders of magnitude in size within a few mill…
Multiple rings in the transitional disk of GM Aurigae revealed by VLA and ALMA
Enrique Macias, Catherine C. Espaillat, Alvaro Ribas +6
Our understanding of protoplanetary disks is rapidly departing from the classical view of a smooth, axisymmetric disk. This is in part thanks to the high angular resolution that (s…

Adam E. Rubinstein, Enrique Macias, Catherine C. Espaillat +3
Herbig Ae/Be (HAeBe) stars have been classified into Group I or Group II, which were initially thought to be flared and flat disks, respectively. Several Group I sources have been…
