摘要: Abstract I modeled the 14 A–37  μ m SED of recurrent symbiotic nova RS Oph during its supersoft source (SSS) phase and following quiescent phase. During SSS phase, model SEDs revealed presence a strong stellar nebular component radiation in spectrum. The former was emitted by burning WD at highly super-Eddington rate, while latter represented fraction reprocessed thermal nebula. transition both components were decreasing quiescence satisfied produced large, optically thick disk ( R > 10 ⊙ ). luminosity independently justified high quantity emission. emitting material surrounded WD, mass 1.6 ± 0.5 ) × - 4 d / kpc 5 2 M . helium ash, deposited on surface whole period, around 8 6 , which yields an average growing rate mass, ∼ 7 yr 1 accreted between outbursts, acc 1.26 constrains accretion 6.3 quiescence, from 2.3 requires 3.6 outburst.
