Meteoritics &Planetary Science, Volume 61, Issue 4, Page 720-738, April 2026.Abstract Mechanisms for metal core formation in rocky planetesimals and planetary embryos remain poorly constrained, in part due to complexities arising from immiscibility in core‐forming liquids at low pressures. To assess the pressure dependence of immiscibility and its role in protoplanetary differentiation, we performed experiments at 3 and 5 GPa ...

Puffed-up Inner Rings and Razor-thin Outer Rings in Structured Protoplanetary Disks
The Astrophysical JournalThe vertical distribution of pebbles in protoplanetary disks is a fundamental property influencing planet formation, from dust aggregation to the assembly of planetary cores.

Substructures in Compact Disks of the Taurus Star-forming Region
The Astrophysical Journal, 2023 Observations of substructure in protoplanetary disks have largely been limited to the brightest and largest disks, excluding the abundant population of compact disks, which are likely sites of planet formation.

Radial drift in warped protoplanetary disks
, 2023 The meter-size barrier in protoplanetary disks is a major challenge in planet formation, for which many solutions were suggested. One of the leading solutions is dust traps, that halt or slow the inward migration of dust particles. The source and profile

Microphysics of Protoplanetary Disks and Exoplanet Atmospheres [PDF]
, 2021 An understanding of planetary histories and characteristics requires an empirical connection between planet formation and evolved planets---a long-sought goal of astrophysics and planetary science.

Confined Chemistry in Space: Zeolite‐Supported Fe13 Nanoclusters Modulate CS Reactivity
Small Structures, Volume 7, Issue 3, March 2026.The study explores how an Fe13 cluster confined in chabazite reshapes the reaction of CS and H2 under astrochemical conditions. Confinement promotes C–S bond cleavage over hydrogenation, directing chemistry toward CH4 and H2S formation. Additional CS enables CS2 and C2 species. Microkinetic analysis identifies protoplanetary environments where zeolites

The Astrophysical JournalThe inward drift of millimeter–centimeter sized pebbles in protoplanetary disks has become an important part of our current theories of planet formation and, more recently, planet composition as well.

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.
