Ionized gas emission in protoplanetary disks with the SKAO
Greta Guidi, Christian Rab, Barbara Ercolano +20
Protoplanetary disks represent a crucial stage in the evolution of Young Stellar Objects towards the formation of fully formed planetary systems. While substantial progress has bee…
From thermal to magnetic driving: spectral diagnostics of simulation-based magnetothermal disc wind models
Michael L. Weber, Eleftheria Sarafidou, Christian Rab +2
Disc winds driven by thermal and magnetic processes are thought to play a critical role in protoplanetary disc evolution. However, the relative contribution of each mechanism remai…
Coordinated Space and Ground-Based Monitoring of Accretion Bursts in a Protoplanetary Disk: Establishing Mid-Infrared Hydrogen Lines as Accretion Diagnostics for JWST-MIRI
Benjamin M. Tofflemire, Carlo F. Manara, Andrea Banzatti +17
In this paper, we establish and calibrate mid-infrared hydrogen recombination lines observed with JWST as accretion tracers for pre-main-sequence stars that accrete from circumstel…
Multi-Observatory Study of Young Stellar Energetic Flares (MORYSEF): No Evidence For Abnormally Strong Stellar Magnetic Fields After Powerful X-ray Flares
Konstantin V. Getman, Oleg Kochukhov, Joe P. Ninan +9
We explore the empirical power-law relationship between X-ray luminosity (Lx) and total surface magnetic flux (Phi), established across solar magnetic elements, time- and disk-aver…
