  • The dust shells of three intermediate-mass stars are observed to lie remarkably close to the photosphere and to be composed of unexpectedly large grains, consistent with mass loss from such stars occurring by means of ejection of this dust by photon scattering rather than as a result of radiation pressure.

  • Adaptive optics wavefront sensors need to be in a pupil plane and are insensitive to certain wavefront-error modes. The authors present a wavefront sensor based on a photonic lantern fibre-mode-converter and deep learning, which can be placed at the same focal plane accessing nondegenerate wavefront information and reconstructing the wavefront.

  • Images from the Subaru Telescope and the Hubble Space Telescope reveal an embedded protoplanet at a wide separation around the star AB Aurigae. The system provides evidence for a long-considered alternative mechanism for forming Jupiter-like planets.

  • Nulling interferometry is a technique combining lights from different telescopes or apertures to observe weak sources nearby bright ones. The authors report the first nulling interferometer implemented in a photonic chip doing spectrally dispersed nulling on several baselines, simultaneously.
