Historic mass loss from the RS Ophiuchi system
Jacco Th. van Loon (Keele University, UK)
TL;DR
This paper models the historical dust environment of RS Ophiuchi, showing that eruptions minimally impact dust and may influence the surrounding interstellar medium, with similar effects observed in T Pyxidis.
Contribution
It provides the first detailed modeling of RS Ophiuchi's dust envelope over time and suggests eruptions shape the interstellar medium.
Findings
Dust envelope remains stable despite eruptions
Eruptions and red giant wind influence the interstellar medium
Similar effects observed in T Pyxidis
Abstract
Dust has been detected in the recurrent nova RS Ophiuchi on several occassions. I model the historical mid-infrared photometry and a recent Spitzer Space Telescope spectrum taken only half a year after the 2006 eruption. The dust envelope is little affected by the eruptions. I show evidence that the eruptions and possibly the red giant wind of RS Oph may sculpt the interstellar medium, and show similar evidence for the recurrent dwarf nova T Pyxidis.
