That nine magnitude range corresponds to a factor of nearly 4000 in luminosity, so the ILOT class may include a wide variety of objects.
The term ILOT first appeared in a 2009 paper discussing the nova-like event NGC 300 OT2008-1.
[3][4] The number of ILOTs known is expected to increase substantially when the Vera C. Rubin Observatory becomes operational.
Kashi and Soker proposed a model for the outburt of ASASSN-15qi,[5] in which a Jupiter-mass planet is tidally destroyed and accreted onto a young main sequence star.
[6] Luminous red novae, believed be caused by the merger of two stars, are classified as ILOTs.
