An Hourglass Inferred from Molecular Motion
An artist’s visualization of the hourglass-shaped molecular outflows emerging around an expanding equatorial dust disc.
An artist’s visualization of the hourglass-shaped molecular outflows emerging around an expanding equatorial dust disc. The form is guided by ALMA’s measured molecular velocities and the researchers’ geometric model, not by a resolved-color photograph of the star.
THE OBSERVATION
What we can actually see.
The 2026 study models optical spectra taken in 2023 and identifies a carbon-rich [WC]-type central-star wind. Its favored atmosphere model has a temperature near 30,500 kelvin, with a range reflecting the analysis. Earlier infrared and millimeter observations constrain surrounding dust and molecular outflows. These observations make different parts of the evolution accessible on human observing timescales.
THE ILLUSTRATION
What the artwork imagines.
An artist’s visualization of the hourglass-shaped molecular outflows emerging around an expanding equatorial dust disc. The form is guided by ALMA’s measured molecular velocities and the researchers’ geometric model, not by a resolved-color photograph of the star. The viewpoint, illumination, colors and simultaneous arrangement are artistic choices. This is a cinematic illustration, not a direct instrument image or a quantitative reconstruction of every feature.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
Sakurai’s Object returned briefly to a swollen giant-like state after a late helium-shell pulse. A identified carbon-rich wind now offers evidence that the obscured remnant is moving into another stage of evolution. This frame focuses on an hourglass inferred from molecular motion, within the complete illustrated article and its source-linked research context.
