Title: Unveiling the inner structure of EXor eruptive variables
Abstract:
We plan to conduct the first comprehensive high spatial resolution
study of EXor objects in order to understand the mechanism regulating
their recurrent accretion outburst and to access the
differences/similarities with respect to other classes of YSO objects
such as FUors and classical T Tauri stars. Here we propose a mini
survey of four EXors that are observable with both CHARA and the VLTI.
We will derive the properties of the inner/outer disk and of emission
line regions with radiative transfer codes and compare the results to
those obtained for T Tauri stars. As the objects will most likely be in
quiescence, these interferometric data will serve as a pre-outburst
baseline for a future comparative analysis between quiescence and
outburst phases, which we plan to perform. To this aim we are now
beginning a photometric and spectroscopic EXor monitoring program that
will ensure we promptly detect any future outburst of known EXors.
