Weekly Update from the Open Journal of Astrophysics – 01/11/2025

It’s time once again for the usual Saturday update of the week’s new papers at the Open Journal of Astrophysics (although a bit later in the day than usual). Since the last update we have published another two papers, which brings the number in Volume 8 (2025) up to 163, and the total so far published by OJAp up to 398.

The first paper this week is “Instability and vertical eccentricity variation in global hydrodynamic disk simulations” by Janosz W Dewberry (U. Mass. Amherst, USA), Henrik N. Latter and Gordon I. Ogilvie (U. Cambridge, UK) and Sebastien Fromang (U. Paris Saclay, France). This article was published in the folder Solar and Stellar Astrophysics on Tuesday 28th October 2025; it discusses the instabilities and eccentricity variations generated in numerical hydrodynamic simulations of accretion disks.

The second (and last) paper of the week is “Fast X-ray Transient Detection with AXIS: application to Magnetar Giant Flares” by Michela Negro (Louisiana State University, USA) and 8 others based in the USA and Canada. This one was also published on Tuesday 28th October, but in the folder High-Energy Astrophysical Phenomena. It presents a feasibility study of detecting Magnetar Giant Flares with the Advanced X-ray Imaging Satellite (AXIS). The overlay is here:

It being a relatively slow week we didn’t reach the 400 mark as I thought we might, but we will probably get there next week. After 10 months of the year 2025, in which we have published 163 papers, a rough projection for the 2025 total is 195. We do have some extra papers up our sleeve, however, so we might well reach 200 for the year. We will find out soon enough!

New cosmic twist: magnetar flares may be responsible for creating gold, platinum, and other heavy elements in the universe. #Magnetars #CosmicAlchemy #HeavyElements

#Magnetare:

Neue #Goldquelle in alten Daten entdeckt.

Ein Ausbruch eines #Magnetars, aufgezeichnet vor 20 Jahren, beinhaltete ein Signal, das nun als #Nukleosynthese verstanden wird. Dabei entstehen schwere Elemente wie #Gold und #Platin.

Ein Forschungsteam aus den USA konnte den r-Prozess, der bereits vor 70 Jahren zumindest theoretisiert wurde, in einem aufgezeichneten Ausbruch eines Magnetars nachweisen.

A forgotten flare from a dead star could explain how the early cosmos got its bling.
