A. AVRAMOVA-BONCHEVA is an academic who published a paper in 2023 entitled Transient and asymmetric dust structures in the TeV-bright nova RS Oph revealed by spectropolarimetr. A. AVRAMOVA-BONCHEVA published this work as part of a team: Nikolov, Y.. Here is a description of this work: A long-standing question related to nova eruptions is how these eruptions can lead to the formation of dust despite the ostensibly inhospitable environment for dust within the hot, irradiated ejecta. Novae in systems such as the symbiotic binary RS Oph offers a articularly clear view of some nova shocks and any associated dust production. Here we use spectropolarimetric monitoring of the RS Oph starting two days after its eruption in 2021 Aug. to show that: dust was present in the RS Oph system as early as two days into the 2021 eruption; the spatial distribution of this early dust was asymmetric, with components both aligned with and perpendicular to the orbital plane of the binary; between two and nine days after the start of the eruption, this early dust was gradually destroyed; and dust was again created, aligned roughl.
