Chemistry on solar system scales
Catherine Walsh, Maria Drozdovskaya, Dmitry Semenov +33
The initial chemical composition of planets, primitive bodies in our solar system, and exoplanets is ultimately set by their nascent protoplanetary disks. Yet observing key carbon-…
Dust Substructures and Line Perturbations driven by a Forming Planet in J16120
Anibal Sierra, Andrés F. Izquierdo, Paola Pinilla +18
Hints of planet formation have been independently reported within the gap of the disc around 2MASS J16120668-301027 from millimetre continuum, infrared, and H-alpha observations. I…
Extending dynamical mass measurements: probing GI as a possible origin of mm-dust spirals
V. Pezzotta, S. Facchini, A. F. Izquierdo +7
Constraining the total mass of protoplanetary disks is crucial to determine the availability of material for planet formation. Yet, providing accurate and precise measurements of t…
Water D/H in 3I/ATLAS as a Probe of Formation Conditions in Another Planetary System
Luis E. Salazar Manzano, Teresa Paneque-Carreño, Martin A. Cordiner +17
Water reservoirs in the Solar System exhibit a deuterium enrichment that links back to the physical environment at the time of stellar birth. Gas-phase and ice-grain deuterium enri…
Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses
Luigi Zallio, Miguel Vioque, Sean M. Andrews +14
Stellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung-Russell (HR) diagrams are strongly model de…
Spirals and Vertical Motions in the Planet-Forming Disk around HD 100546. A multi-line study of its gas kinematics
Lisa Wölfer, Andrés F. Izquierdo, Alice Booth +5
HD100546 represents a particularly interesting target to study dynamical planet-disk interactions as various features have been observed in both the dust and gas that provide direc…
The 12CO Gas Structures of Protoplanetary Disks in the Upper Scorpius Region
Luigi Zallio, Giovanni P. Rosotti, Miguel Vioque +13
We present measurements of key protoplanetary disk properties inferred from parametric models of ALMA 12CO spectral line visibilities. We derive gas-disk radii, integrated fluxes,…
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 XV: Interpreting the height of CO emission layer
Giovanni P. Rosotti, Cristiano Longarini, Teresa Paneque-Carreño +32
The availability of exquisite data and the development of new analysis techniques have enabled the study of emitting heights in proto-planetary disks. In this paper we introduce a…
Mapping the merging zone of late infall in the AB Aur planet-forming system
Jessica Speedie, Ruobing Dong, Richard Teague +10
Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA CO and SO observ…
Vertical CO surfaces as a probe for protoplanetary disk mass and carbon depletion
T. Paneque-Carreño, A. Miotello, E. F. van Dishoeck +2
As the sample of mid-inclination disks with measured CO emission surfaces grows, a fundamental unanswered question is how these vertical profiles connect to their host properties.…
Gravitational instability in a planet-forming disk
Jessica Speedie, Ruobing Dong, Cassandra Hall +7
The canonical theory for planet formation in circumstellar disks proposes that planets are grown from initially much smaller seeds. The long-considered alternative theory proposes…
Angular momentum transport via gravitational instability in the Elias 2-27 disc
Cristiano Longarini, Giuseppe Lodato, Cathie J. Clarke +6
Gravitational instability is thought to be one of the main drivers of angular momentum transport in young protoplanetary discs. The disc around Elias 2-27 offers a unique example o…
C I Traces the Disk Atmosphere in the IM Lup Protoplanetary Disk
Charles J. Law, Felipe Alarcón, L. Ilsedore Cleeves +2
The central star and its energetic radiation fields play a vital role in setting the vertical and radial chemical structure of planet-forming disks. We present observations that, f…
