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…
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…
The ODYSSEUS Survey. Motivation and First Results: Accretion, Ejection, and Disk Irradiation of CVSO 109
C. C. Espaillat, G. J. Herczeg, T. Thanathibodee +59
The Hubble UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Director's Discretionary Program of low-mass pre-main-sequence stars, coupled with forthcoming data fro…
Evidence for an MHD disk wind via optical forbidden line spectro-astrometry
E. T Whelan, I. Pascucci, U. Gorti +4
Spectro-astrometry is used to investigate the low velocity component (LVC) of the optical forbidden emission from the T Tauri stars RU Lupi and AS 205 N. Both stars also have high…
