Modeling and interpretation of images*
EPJ Web of Conferences, 2015 Imaging protoplanetary disks is a challenging but rewarding task. It is challenging because of the glare of the central star outshining the weak signal from the disk at shorter wavelengths and because of the limited spatial resolution at longer ...

The Disk Substructures at High Angular Resolution Project (DSHARP). V. Interpreting ALMA Maps of Protoplanetary Disks in Terms of a Dust Model [PDF]
Astrophysical Journal, 2018 The Disk Substructures at High Angular Resolution Project (DSHARP) is the largest homogeneous high-resolution (∼0.″035, or ∼5 au) disk continuum imaging survey with the Atacama Large Millimeter/submillimeter Array (ALMA) so far. In the coming years, many

Low EUV Luminosities Impinging on Protoplanetary Disks [PDF]
, 2014 The amount of high-energy stellar radiation reaching the surface of protoplanetary disks is essential to determine their chemistry and physical evolution. Here, we use millimetric and centimetric radio data to constrain the EUV luminosity impinging on 14

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 122-139, January 2026.Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a

Light Echoes of Protoplanetary Disks
The Astrophysical JournalLight echoes offer a means of studying protoplanetary disks, including their geometry and composition, even when they are not spatially resolved. We present a test of this approach applied specifically to optically thick, geometrically flared disks ...

Radiation hydrodynamics including irradiation and adaptive mesh refinement with AZEuS. I. Methods
, 2014 Aims. The importance of radiation to the physical structure of protoplanetary disks cannot be understated. However, protoplanetary disks evolve with time, and so to understand disk evolution and by association, disk structure, one should solve the ...

Global Simulations of the Inner Regions of Protoplanetary Disks with Comprehensive Disk Microphysics [PDF]
, 2017 The gas dynamics of weakly ionized protoplanetary disks (PPDs) are largely governed by the coupling between gas and magnetic fields, described by three non-ideal magnetohydrodynamical (MHD) effects (Ohmic, Hall, ambipolar).

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution
AGU Advances, Volume 6, Issue 6, December 2025.Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

Abundant Refractory Sulfur in Protoplanetary Disks [PDF]
Astrophysical Journal, 2019 Sulfur is one of the most abundant elements in the universe, with important roles in astro-, geo-, and biochemistry. Its main reservoirs in planet-forming disks have previously eluded detection: gaseous molecules only account for
