Thrilled to share that we made the cover of @natastron.nature.com!!! 🔭💥☄️ The artwork, designed in collaboration with @ozgrav.bsky.social, features a rendering of the magnetic field simulation from our white dwarf binary paper. Check it out here: www.nature.com/natastron/vo...

Journal cover for Nature Astronomy, August 2026 issue. The background is a textured deep teal field filled with faint white grid lines and loops depicting magnetic fields. On the upper left, a large, textured reddish-orange star is shown. On the lower right, a small, bright white-blue dwarf star is encircled by a dense, flower-like array of magnetic field lines. A stylised, ribbon-like stream of white and blue light connects the two celestial objects across the centre. Bold white text in the lower-left corner reads "White dwarf binaries as long-period radio emitters."

We've discovered two more long period transients! A new @pasajournal.bsky.social paper by Yuanming Wang and collabs introducing the VASTER pipeline running on ASKAP. As soon as we switched it on we started finding new things (star and LPT below) dx.doi.org/10.1017/pasa... #radioastro ☄️

Image caption from paper. https://dx.doi.org/10.1017/pasa.2026.10232

Examples of transient detections in the time-averaged deep images and short-timescale residual images, plotted from the VASTER outputs, for two sources: the flaring star ASKAP J051629.6–313543 (top row) and the LPT ASKAP J165130.3–450520 (bottom row).

From left to right in each row: the time-averaged deep image, the residual image prior to the flare, the residual image during the flare, and the residual image after the flare. The white circle marks the target source position, with a radius of 20 arcsec.

We've discovered another long period transient with ASKAP! Source #15 in this small but growing population. It repeats every 36 minutes, but despite many observations (see plot) we're not sure what it is. New paper by Joshua Pritchard: doi.org/10.1017/pasa... #radioastro

Lightcurves from all ASKAP, ATCA, and MeerKAT radio observations of a long period transient: ASKAP J142431.2–612611

They are phase-folded to the radio period of 2 147.27 s. Green shading indicates the range of uncertainty in predicted pulse time around the expected pulse phase of 0.5.

The VAST Extragalactic Survey footprint, showing the number of observations of each field. The sky map is plotted with J2000 equatorial coordinates in the Mollweide projection. The VAST Galactic survey is plotted in grey for reference. Typically, each field has been observed 10–11 times to date.

There are 4 rows. Each row represents a different source.

Each row has three panels.

Left: VAST Extragalactic DR1 light curve. Black points are integrated flux density measurements from Selavy. White points are the forced-fitted flux density for images where there was no Selavy detection.

Middle: VAST cutout for the epoch with the maximum flux density, the ellipse in the lower right corner of the radio image shows the FWHM of the restoring beam.
