Unstable accretion in TW Hya: 3D simulations and comparisons with observations
M. M. Romanova, C. C. Espaillat, J. Wendeborn +3
We investigate the origin of photometric variability in the classical T Tauri star TW Hya by comparing light curves obtained by TESS and ground-based telescopes with light curves c…
Density streams in the disc winds of Classical T Tauri stars
P. P. Petrov, K. N. Grankin, E. V. Babina +5
Spectral and photometric variability of the Classical T Tauri stars RY Tau and SU Aur from 2013 to 2022 is analyzed. We find that in SU Aur the H-alpha line's flux at radial veloci…
3D Simulations of Planet Trapping at Disc-Cavity Boundaries
M. M. Romanova, P. S. Lii, A. V. Koldoba +4
Inward migration of low-mass planets and embryos of giant planets can be stopped at the disc-cavity boundaries due to co-orbital corotation torque. We performed the first global th…
Accretion dynamics in the classical T Tauri star V2129 Oph
S. H. P. Alencar, J. Bouvier, F. M. Walter +9
We analyze the photometric and spectroscopic variability of the classical T Tauri star V2129 Oph over several rotational cycles to test the dynamical predictions of magnetospheric…
Torsional Magnetic Oscillations in Type I X-Ray Bursts
Richard V. E. Lovelace, Akshay K. Kulkarni, Marina M. Romanova
Thermonuclear burning on the surface of a neutron star causes the expansion of a thin outer layer of the star, . The layer rotates slower than the star due to angular moment…
