  The latest results from our ongoing multiplicity study of (Community) TESS
Objects of Interest are presented, using astro- and photometric data from the
ESA-Gaia mission, to detect stellar companions of these stars and characterize
their properties. A total of 124 binary and 7 hierarchical triple star systems
were detected among 2175 targets, whose multiplicity was investigated in the
course of our survey, which are located at distances closer than about 500pc
around the Sun. The detected companions and the targets are located at the same
distance and share a common proper motion, as expected for components of
gravitationally bound stellar systems, as proven with their accurate Gaia EDR3
astrometry. The companions have masses in the range between about 0.09 and
2.5$M_\odot$ and are most frequently found in the mass range between 0.15 and
0.8$M_\odot$. The companions exhibit projected separations to the targets
between about 50 to 9700au and their frequency is the highest and constant up
to about 500au, while it decreases for larger projected separations. In
addition to mainly mid M to early K dwarfs, 4 white dwarf companions were
detected in this survey, whose true nature could be identified with their
photometric properties.
