Multiple and multiply-eclipsing stellar systems

ABSTRAKT / ABSTRACT :

The number of close multiple systems showing multiple
eclipses and strong dynamical effects is quickly increasing.
An important source of new high-precision and continuous photometric
observations is TESS. Combination of the ground-based multi-color
photometry and high-resolution spectroscopy revealed the nature of several
systems and lead to the detection of the tightest quadruple system
with co-planar orbits, BU CMi. Using multiple observations including light-curves,
line profiles, timing variability and spectral-energy distribution and taking into
account dynamical perturbations enabled us to reliably characterize the systems.
