  We study the pre-explosion outbursts (PEOs) of massive stars that might
result from a rapid expansion of the massive star in the presence of a close
companion. We assume that activity in the core of the massive star, an initial
mass of 15Mo, about two years before explosion energizes the envelope, and with
the stellar evolutionary code MESA follow the inflated envelope as a result of
energy deposition to the envelope. We examine the conditions for a companion
star to accrete mass from the inflated envelope. We find that for the general
conditions that we assume, bright PEOs require a neutron star companion at an
orbital separation of about 1000-2000Ro. We assume that the mass-accreting
neutron star launches jets. These jets shape the circumstellar matter to highly
non-spherical structures, such that the explosions of core collapse supernovae
(CCSNe) that follow PEOs might lack an axial (cylindrical) symmetry. In some
case main sequence star companions can also energize PEOs, but much weaker
ones. This study adds another scenario by which neutron stars can power the
radiation of PEOs. Another scenario is the common envelope jets supernova
(CEJSN) impostor where a neutron star enters the envelope of the massive star.
