Ultraviolet Imaging of SR 12 c with HST/WFC3: Accretion and Variability of a Giant Planet at the End Stages of Growth
Claire O. Finley, Brendan P. Bowler, Ya-Lin Wu +12
Many details of the gas accretion phase during giant planet formation remain untested. We present new 0.2$\unicode{x2013}$0.7 m UV-through-red optical imaging of the young, wid…
The Ultraviolet View of Star and Planet Formation: Disks, Accretion, and Outflows with the Hubble Space Telescope into the 2030s
Kevin France, Eric Gaidos, Catherine Espaillat +2
The spatial distribution and lifetime of molecular gas in the inner regions of young circumstellar disks are key to understanding the formation of planetary systems. Gas-rich disks…
3D MHD simulations of planet migration in cavities and inner discs of magnetized stars
M. M. Romanova, A. V. Koldoba, G. V. Ustyugova +2
We investigate the Type I migration of planets in low-density cavities and inner discs of strongly magnetized young stars using global three-dimensional (3D) magnetohydrodynamic (M…
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…
