High-resolution Imaging of the Magnetic Reconfiguration of the Corona from inside the Corona by WISPR on Parker Solar Probe

The Astrophysical Journal Letters
During the 22nd perihelion of Parker Solar Probe at 9.86 solar radii on 2024 December 24, the WISPR telescope captured a detailed sequence of events marking the return of open magnetic flux back to the Sun via the heliospheric current sheet (HCS ...

On-sky Demonstration of Subdiffraction-limited Astronomical Measurement Using a Photonic Lantern

The Astrophysical Journal Letters
Resolving fine details of astronomical objects provides critical insights into their underlying physical processes. This drives in part the desire to construct ever-larger telescopes and interferometer arrays and to observe at shorter wavelengths to ...

JWST/NIRCam Coronagraphic Search for Hidden Planets in the HD 163296 Protoplanetary Disk

The Astronomical Journal
HD 163296 is a Herbig Ae/Be star with multiple signposts of ongoing planet formation on its disk, such as prominent rings and gaps, as well as kinematic features as identified by previous Atacama Large Millimeter/submillimeter Array (ALMA) observations ...
