Query: Gaia Search for stellar Companions of TESS Objects of Interest II   We present the latest results of our ongoing multiplicity study of
(Community) TESS Objects of Interest, using astro- and photometric data from
the ESA-Gaia mission, to detect stellar companions of these stars and to
characterize their properties. In total, 113 binary, 5 hierarchical triple star
systems, as well as one quadruple system were detected among 585 targets
surveyed, which are all located at distances closer than about 500pc around the
Sun. As proven with their accurate Gaia EDR3 astrometry the companions and the
targets are located at the same distance and share a common proper motion, as
it is expected for components of gravitationally bound stellar systems. The
companions exhibit masses in the range between about 0.09$M_\odot$ and
4.5$M_\odot$ and are most frequently found in the mass range between 0.15 and
0.6$M_{\odot}$. The companions are separated from the targets by about 120 up
to 9500au and their frequency is the highest and constant within about 500au
while it continually decreases for larger separations. Beside mainly early to
mid M dwarfs, also 5 white dwarf companions were identified in this survey,
whose true nature was revealed by their photometric properties.
