The distribution of accretion rates as a diagnostic of protoplanetary disc evolution
R. Alexander, G. Rosotti, P. J. Armitage +3
We show that the distribution of observed accretion rates is a powerful diagnostic of protoplanetary disc physics. Accretion due to turbulent ("viscous") transport of angular momen…
The surprising evolution of the shadow on the TW Hya disk
J. Debes, R. Nealon, R. Alexander +8
We report new total intensity visible light high contrast imaging of the TW Hya disk taken with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope (HST).…
Lyman-alpha Scattering Models Trace Accretion and Outflow Kinematics in T Tauri Systems
Nicole Arulanantham, Max Gronke, Eleonora Fiorellino +18
T Tauri stars produce broad Lyman-alpha emission lines that contribute 88% of the total UV flux incident on the inner circumstellar disks. Lyman-alpha photons are generated a…
Dust dynamics in planet-forming discs in binary systems
Francesco Zagaria, Giovanni P. Rosotti, Richard D. Alexander +1
In multiple stellar systems interactions among the companion stars and their discs affect planet formation. In the circumstellar case tidal truncation makes protoplanetary discs sm…
An unusual reservoir of water emission in the VV CrA A protoplanetary disk
Colette Salyk, Klaus M. Pontoppidan, Andrea Banzatti +7
We present an analysis of an unusual pattern of water vapor emission from the 2 Myr-old low-mass binary system VV CrA, as observed in infrared spectra obtained with VLT-CRIRE…
Inward and outward migration of massive planets: moving towards a stalling radius
C. E. Scardoni, C. J. Clarke, G. P. Rosotti +3
Recent studies on the planet-dominated regime of Type II migration showed that, contrary to the conventional wisdom, massive planets can migrate outwards. Using `fixed-planet' simu…
