Protostellar Outflows at the EarliesT Stages (POETS). IX. Magnetohydrodynamic disk winds traced by SO and SO in luminous protostars
L. Moscadelli, H. Beuther, A. Sanna +13
We investigate two massive young stellar objects (YSOs), IRAS21078+5211 and G035.02+0.35, where evidence for magnetohydrodynamic (MHD) disk winds (DWs) has been obtained at scales…
A Validated Low-to-Intermediate Mass Planetary Interior Structure Model and New Mass-Radius Relations
Bennett Neil Skinner, Ralph E. Pudritz, Ryan Cloutier
The increasing precision of planetary mass and radius observations is bringing major questions about the structure and formation of planets--such as the nature of the radius valley…
Reading between the rings: observed dust ring properties as probes of planet masses
Amena Faruqi, Jessica Speedie, Ralph E. Pudritz +1
We hypothesise that dust rings in protoplanetary discs formed by an embedded planet should have properties that reflect the planet's mass. We use 2D hydrodynamical simulations of p…
Revealing the Connection Between the Filamentary Hierarchy and Star Cluster Formation in a Simulated NGC 628 Galaxy
Tamara Koletic, Rachel Pillsworth, Ralph E. Pudritz
There is abundant observational evidence for the hierarchical, interconnected nature of filaments in the interstellar medium (ISM) extending from galactic down to sub-parsec scales…
On the relation between magnetic field strength and gas density in the interstellar medium. II. Density uncertainties and diffuse gas constraints
David Whitworth, Amit Seta, Ralph E. Pudritz +4
The relationship between magnetic field strength and gas density is essential to understand the interstellar medium and star formation. Zeeman measurements in dense atomic and mole…
Filamentary Hierarchies and Superbubbles II: Impact of superbubbles and galactic dynamics on filament formation and fragmentation
Rachel Pillsworth, Ralph E. Pudritz, Eric W. Koch +1
Large scale phenomena in spiral galaxies such as shear, supernovae, and magnetic fields all contribute to the formation and subsequent evolution of filamentary structure and star f…
