Preparing for the Early eVolution Explorer: Photometric Diagnostics of Magnetospheric Accretion Geometry in Young Stellar Objects
Laura Venuti, Connor E. Robinson, Ann Marie Cody +13
The inner disk truncation radius, , plays a crucial role in the regulation of star-disk interaction and the early evolution of star-disk-planet systems; however, measuring thi…
The effect of variable stellar magnetic fields on the spin state of T Tauri stars
Lukas Gehrig, Daniel Steiner
Understanding the stellar spin evolution of young stars is crucial for understanding the evolution of protoplanetary disks and, consequently, the formation of exoplanets. According…
Protoplanetary disks around magnetized young stars with large-scale magnetic fields I: Steady-state solutions
D. Steiner, L. Gehrig, M. Güdel
Describing the large-scale field topology of protoplanetary disks faces significant difficulties and uncertainties. The transport of the large-scale field inside the disk plays an…
Do accretion-powered stellar winds help spin down T Tauri stars?
Lukas Gehrig, Eric Gaidos, Laura Venuti +2
How T Tauri stars remain slowly rotating while still accreting material is a long-standing puzzle. Current models suggest that these stars may lose angular momentum through magneto…
The post-disk (or primordial) spin distribution of M dwarf stars
L. Gehrig, E. Gaidos, M. Güdel
We investigate the influence of an accretion disk on the angular momentum (AM) evolution of young M dwarfs, which parameters govern the AM distribution after the disk phase, and wh…
What governs the spin distribution of very young < 1 Myr low mass stars
L. Gehrig, E. I. Vorobyov
We compute the evolution and rotational periods of young stars, using the MESA code, starting from a stellar seed, and take protostellar accretion, stellar winds, and the magnetic…
The influence of metallicity on a combined stellar and disk evolution
L. Gehrig, T. Steindl, E. I. Vorobyov +2
The effects of an accretion disk are crucial to understanding the evolution of young stars. During the combined evolution, stellar and disk parameters influence each other, motivat…
Time-dependent, long-term hydrodynamic simulations of the inner protoplanetary disk II: The importance of stellar rotation
Lukas Gehrig, Daniel Steiner, Eduard Vorobyov +1
The spin evolution of young protostars, surrounded by an accretion disk, still poses problems for observations and theoretical models. In recent studies, the importance of the magn…
Time-dependent, long-term hydrodynamic simulations of the inner protoplanetary disk I: The importance of stellar magnetic torques
D. Steiner, L. Gehrig, B. W. Ratschiner +4
We conduct simulations of the inner regions of protoplanetary disks (PPDs) to investigate the effects of protostellar magnetic fields on their long-term evolution. We use an inner…
Mass limits for stationary protoplanetary accretion disks
Florian Ragossnig, Lukas Gehrig, Ernst A. Dorfi +2
The collapse of interstellar gaseous clouds towards a protostar leads to the formation of accretion disks around the central star. Such disks can be dynamically stable if they sett…
