The study of sub-stellar and planetary objects is of great importance in astronomy, clearly reflected by the rapidly increasing number of published works on this topic. A wide variety of techniques have been used for probing these objects, being interferometry (both at radio and infrared wavelengths) a technique that provides unique insights into the physics and dynamics of these interesting objects due to its high angular resolution.
We will present radio and infrared interferometry observations of a group of stellar and sub-stellar objects. We will discuss our detections and non-detections and what conclusions can be achieved using the interferometry technique, such as: evidence for a substellar companion to a brown dwarf, determination of dynamical masses in binary objects, comprehend radio emission in ultracool dwarfs in order to better understand the possible radio emission of exoplanets, localizing radio emission in multiple-objects systems with high spatial precision, etc.
