Polarimetry and spectroscopy of the 'oxygen flaring' DQ Herculis-like nova: V5668 Sagittarii (2015).
Harvey, E. J.; Redman, M.P.; Darnley, M.J.; Williams, S.C.; Beredyugin, A.; Piirola, V.E.; Fitzgearld, K.P.; O'Connor, P.O. (EDP Sciences, 2018-09-05)Context. Classical novae are eruptions on the surface of a white dwarf in a binary system. The material ejected from the white dwarf surface generally forms an axisymmetric shell of gas and dust around the system. The ... -
Shock shaping? Nebular spectroscopy of nova V906 Carinae
Harvey, E.J.; Aydi, E.; Izzo, L.; Morisset, C.; Darnley, M.J.; Fitzgerald, Karol; Molaro, P.; Murphy-Glaysher, F.; Redman, M.P.; Shrestha, M. (Oxford University Press, 2023-03-22)V906 Carinae was one of the best observed novae of recent times. It was a prolific dust producer and harboured shocks in the early evolving ejecta outflow. Here, we take a close look at the consequences of these early ... -
Two new Nova Shells associated with V4362 Sagittarii and DO Aquilae
Harvey, E.J.; Redman, M.P.; Boumis, P.; Fitzgearld, Karol; Dulaimi, S.C.; Williams, S.C.; Darnley, M.J.; Lam, M.C.; Kopsacheilli, M.; Derlopa, S. (Oxford Academic, 2020-09)A classical nova is an eruption on the surface of a white dwarf in an accreting binary system. The material ejected from the white dwarf surface generally forms an axisymmetric shell. The shaping mechanisms of nova shells ...
