The circumstellar matter of type II intermediate luminosity optical transients (ILOTs)

Abstract: I find that a ≃ 0.1 − 1 M ⊙ outflowing equatorial dusty disk (torus) that the binary system progenitor of an intermediate luminosity optical transient (ILOT) ejects several years to several months before and during the outburst can reduce the total emission to an equatorial observer by two orders of magnitude and shifts the emission to wavelengths of mainly λ ≳ 10 μm. This is termed a type II ILOT (ILOT II). To reach this conclusion, I use calculations of type II active galactic nuclei and ap… Show more

“…The outflowing equatorial dusty disk (torus) that the binary system ejects several years to several months before and during the outburst reduces the luminosity that an equatorial observer infers. The attenuation in wavelengths of λ < 5 μm can be more than 3 orders of magnitude (Soker 2021). Another object that might be explained by this scenario is the massive star M51-DS1 that reappeared after its near disappearance Jencson et al (2022).…”

“…Neustadt et al (2021) consider this variability to be a failed CCSN. Kashi & Soker (2017b) and Soker (2021), on the other hand, proposed and developed the type II ILOT scenario for N6946-BH1 and similar events. According to the type II ILOT scenario the binary interaction that powers the ILOT ejects a dense equatorial outflow of 0.1-1 M e .…”

“…In other words, while according to the delayed neutrino mechanism the formation of a BH occurs in a failed CCSN that yields only a faint transient event (e.g., Nadezhin 1980;Lovegrove & Woosley 2013), according to the fixed axis explosion process of the jittering jets explosion mechanism the formation process of a BH in a CCSN is accompanied by the most energetic CCSN explosions (e.g., Gilkis et al 2016;Soker 2017). For example, according to the picture of the jittering jets explosion mechanism the transient event that some attribute to a failed CCSN (e.g., Adams et al 2017;Basinger et al 2021) might be a supernova impostor, like a type II intermediate luminosity optical transient (Kashi & Soker 2017;Soker 2021;Bear, Soker, & Kashi 2022).…”

“…They are conventionally designated as luminous red novae (LRNe; e.g., see Kochanek et al 2014;Pejcha et al 2016Pejcha et al , 2017Smith et al 2016;Blagorodnova et al 2017;Lipunov et al 2017;MacLeod et al 2017;Cai et al 2019;Pastorello et al 2019aPastorello et al ,b, 2021a. The LRN phenomenon is usually interpreted as a post-common-envelope-ejection phase in a contact binary system, and may be followed by stellar coalescence (e.g., see Munari et al 2002;Soker & Tylenda 2003Tylenda et al 2011;Soker & Kashi 2016;Smith et al 2016;Lipunov et al 2017;Mauerhan et al 2018;Pastorello et al 2019b;Soker 2021).…”
