Konstantin Batygin's research is primarily aimed at understanding the formation and evolution of planetary systems. In 2010, Konstantin Batygin and David J. Stevenson published a calculation, which showed that hot Jupiters can become inflated as a consequence of Ohmic dissipation of electrical currents induced through an interaction between ionized atmospheric winds and the planetary magnetic field. In 2012, Batygin demonstrated that misalignments between stellar spin-axes and planetary orbits can arise from gravitational perturbations exerted onto protoplanetary disks by primordial companions stars. In 2015, Batygin and Laughlin hypothesized that the Solar System once possessed a population of short-period planets that were destroyed by Jupiter's migration through the solar nebula. In January 2016, Konstantin Batygin and Michael E. Brown proposed the existence of a ninth planet in the Solar System.
