Abstract: Studying the relative orientations of the orbits of exoplanets and wide-orbiting binary companions (semimajor axis greater than 100 AU) can shed light on how planets form and evolve in binary systems. Previous observations by multiple groups discovered a possible alignment between the orbits of visual binaries and the exoplanets that reside in them. In this study, using data from textit{Gaia} DR3 and TESS, we confirm the existence of an alignment between the orbits of small planets $(RarXiv:2405.10379v1 Announce Type: new
