Weekly Update from the Open Journal of Astrophysics 01/08/2026

It’s time once more for another Saturday update of activity at the Open Journal of Astrophysics. Since the last update we have published a further three papers, bringing the number in Volume 9 (2026) to 163 and the total so far published by OJAp up to 611. I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also show the DOI for each paper.
