text: The central star is in fact a binary system composed of a white dwarf and a companion in a close orbit.
text: At least partially; it’s also possible these stars were binary, and consumed their partner star.
text: Gravitational interactions with companion stars if the central stars are binary stars may be one cause.
text: In fact, visible in the telescopic image the central star of NGC 1360 is known to be a binary star system likely consisting of two evolved white dwarf stars, less massive but much hotter than the Sun.
text: That star might also be part of a binary system, meaning that as many as four stars may be responsible for the structure.
text: These include interactions of the nebular gas with magnetic fields from the central stars,3 interactions between material moving away from the star at different speeds, multiple ejection events, and, in the case of strongly bipolar nebulae, gravitational interactions with companion stars if the central stars are members of binary systems.
text: Results appear consistent with a hypothesis that the dying star is part of a binary star system with a precessing symmetry axis.
text: The star at the centre of the nebula is a binary system.
