In recent years Soker has studied Intermediate Luminosity Optical Transients (ILOTS), which are stellar eruptions with luminosity between a nova and a supernova. One of the prototypes for such an event is V838 Monocerotis, that according to Soker's model, erupted as a merger of two main-sequence stars that underwent a merger process. Soker and his collaborators claim there is a strong connection between V838 Mon-like eruptions and supernova impostors.
