Nature Astronomy, Published online: 08 October 2026; doi:10.1038/s41550-026-03000-7Detailed models for the complete evolution of mass-transferring binary stars produce merging black holes consistent with the observed masses and spins. Isolated binary evolution probably contributes to the observed gravitational-wave sources.

Nature Astronomy, Published online: 05 October 2026; doi:10.1038/s41550-026-02983-7Niobium has been detected in the atmosphere of a young white dwarf, probably originating from a second-generation planet candidate being evaporated by the white dwarf. The planet probably formed from material ejected during the white dwarf progenitor’s death throes.

Nature Astronomy, Published online: 05 October 2026; doi:10.1038/s41550-026-02982-8The detection of niobium in a white dwarf reveals a pollutant unlike any Solar System body, pointing to a ‘second-generation’ giant planet candidate built from debris shed during its host star’s death.

Nature Astronomy, Published online: 08 September 2026; doi:10.1038/s41550-026-02970-yHeliobiology is a new interdisciplinary field that links heliophysics, astrophysics, planetary science and chemistry with an astrobiological focus. We propose a formal definition of heliobiology and a practical framework for its implementation.

Nature Astronomy, Published online: 09 September 2026; doi:10.1038/s41550-026-02959-7Hypersoft X-ray sources are found in an observational blind spot; they can be extremely luminous in the X-ray band and extreme ultraviolet, and are likely to be X-ray binary systems. Their energetics suggest that they play a crucial role in ionizing galaxies.
