Using the Ca II lines in T Tauri stars to infer the abundance of refractory elements in the innermost disk regions
Marbely Micolta, Nuria Calvet, Thanawuth Thanathibodee +5
We present a study of the abundance of calcium in the innermost disk of 70 T Tauri stars in the star-forming regions of Chamaeleon I, Lupus and Orion OB1b. We use calcium as a prox…

Evidence for magnetic boundary layer accretion in RU Lup. A spectrophotometric analysis
A. Armeni, B. Stelzer, A. Frasca +9
The aim of this work is to characterize the accretion process of the classical T Tauri Star RU Lup. We studied optical high-resolution spectroscopic observations from CHIRON and ES…

FitteR for Accretion ProPErties of T Tauri stars (FRAPPE): A new approach to use Class III spectra to derive stellar and accretion properties
R. A. B. Claes, J. Campbell-White, C. F. Manara +10
Studies of the stellar and accretion properties of classical T Tauri stars (CTTS) require comparison with photospheric spectral templates. Here we aim at expanding the currently av…
