Weekly Update from the Open Journal of Astrophysics – 11/04/2026
With permission, I have time for yet another Saturday morning update of activity at the Open Journal of Astrophysics. Since the last update we have published a further five papers, bringing the number in Volume 9 (2026) to 76 and the total so far published by OJAp up to 524.
I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter (which nobody should be using); these announcements also show the DOI for each paper.
The first paper to report this week is “Lagrangian versus Eulerian Methods for Toroidally-Magnetized Isothermal Disks” by Yashvardhan Tomar and Philip F. Hopkins (California Institute of Technology, USA). This study re-evaluates previous research on toroidally-magnetized disks, using two Lagrangian methods. The results suggest that sustained midplane toroidal fields in recent simulations are not a numerical artefact. It was published on Tuesday April 7th 2026 in the folder High-Energy Astrophysical Phenomena.
The overlay is here:
You can find the officially accepted version on arXiv here and the announcement on Fediverse here:
https://fediscience.org/@OJ_Astro/116362395042011770
The second paper for this week, published on Wednesday 8th Apil in the folder Instrumentation and Methods for Astrophysics, is “Teaching Astronomy with Large Language Models” by Yuan-Sen Ting and Teaghan O’Briain (Ohio State University, USA). The paper introduces AstroTutor, an AI-enhanced astronomy tutoring system, to improve undergraduate astronomy education and AI literacy. It found that structured AI integration can enhance learning and critical evaluation skills. The primary classification on arXiv for this paper is physics.ed-ph but it is cross-listed on astro-ph which qualifies it for consideration.
The overlay for this one is here:
The official version of the paper can be found on arXiv here and the Fediverse announcement here:
https://fediscience.org/@OJ_Astro/116368195945602700
Next one up, the third paper of the week, also published on Wednesday 8th April, is “Statistical Predictions of the Accreted Stellar Halos around Milky Way-Like Galaxies” by J. Sebastian Monzon & Frank C. van den Bosch (Yale University, USA) and Martin P. Rey (University of Bath, UK). This one was published in the section Astrophysics of Galaxies; it describes new model to track formation of stellar halos in Milky Way-like galaxies, revealing their sensitivity to the fate of the largest satellite and whether accretion is early or late.
The overlay for this one is here:
The final, accepted version can be found on arXiv here and the Mastodon announcement is here:
The fourth paper this week, published on Thursday 9th April is “A Tale of Tails: Star Formation and Stripping in Jellyfish Galaxies in the Strong Lensing Cluster MACS J0138.0-2155” by Catherine C. Gibson, Jackson H. O’Donnell and Tesla E. Jeltema (UC Santa Cruz, USA). This investigates the effects of ram-pressure stripping on four galaxies, focusing on their stellar and gas kinematics, star formation rates, and galactic structure and is published in the folder marked Astrophysics of Galaxies.

The finally accepted version of this paper can be found here and the Mastodon announcement is here:
https://fediscience.org/@OJ_Astro/116374103962641944
The fifth and final paper for this week is “Investigating ionising sources and the complex interstellar medium of GHZ2 at z=12.3” by M. Castellano (INAF Osservatorio Astronomico di Roma, Italy) and 29 others based all around the world. This was also published on Thursday 9th April in the folder Astrophysics of Galaxies. The paper uses deep observations of galaxy GHZ2 to explore the sources of ionising radiation and interstellar medium properties at cosmic dawn. Findings suggest a stratified environment and a hard ionising radiation component.

That concludes this week’s update. I’ll do another one at the end of next week, when the Easter vacations will be over.

• Strong contrasts between east-facing (Irish Sea) and south-facing (Atlantic) coasts
• Identification of critical erosion hotspots (e.g., Tramore) and accretion zones in embayments
• Coastal change is driven by a combination of wave climate, sediment availability, geology, and human activity

• Coastlines are highly dynamic — 57% accretion vs 42% erosion
• Strong contrasts between east-facing (Irish Sea) and south-facing (Atlantic) coasts
• Identification of critical erosion hotspots (e.g., Tramore) and accretion zones in embayments

🪐 First direct #imaging of a forming #exoplanet carving multiple rings in its accretion disk! Van Capelleveen et al. (2025) reveal a ~5 MJup #protoplanet 57 AU (~8.5 billion km, farther than Pluto) from its star (#WISPIT2, ~133 pc) with #VLT/SPHERE, showing #Keplerian motion and Hα #accretion. A rare, striking view of planet–disk interaction in real time 💫

The plot in question:
It's a figure I made for my #thesis that shows the #relativistic emissivity pattern of an #accretion disc illumed by an off-axis hot X-ray corona around a spinning #blackhole
The radial axis is logarithmic (up to 100 rg). The corona is located at 10 rg on the right. Labels are logarithms of emissivity.
The curvature of spacetime is lensing the photons from the corona onto the innermost regions, and causes the spiral-like deformation from the frame-dragging effect.

ALMA captured, for the first time, the accretion flow _towards_ a supermassive black hole. Identifying this flow had long been a challenge, due to the small scale of these regions and the complex gas motion near galactic centers. They saw where the foreground molecular gas absorbed the bright light coming from the Active Galaxy Nucleus, and evidence of its movement.

A 'simple' #model by Chambers for the early #formation epochs of the #Solar System, where the #evolution of the solar #nebula is driven by a disc #wind. The model finds that outside the #ice line #pebble #accretion is the dominant #planetary #embryo formation mechanism, whereas inside the ice line it is planetesimal accretion that dominantes embryo growth!!

The year a giant helmet pushed up from the ground should have set off alarm bells but it turned into a tourist attraction. It was four stories high and almost that wide. Very few questioned it. A few tried to dug under it with no success. Something supernatural was prevented it. No one knew the #accretion happening below. World ending doom, coming soon Earthlings.

Different types of moons, perhaps unsurprisingly, are thought to come from different origins. Here are some theories Earth humans have come up with so far: accretion and capture.

There are a number theories that have been put forward for moon formation, but accretion and capture are the most common for explaining the majority of the moons in our Solar System. Other theories include fission and impact. Learn more about moons: https://solarsystem.nasa.gov/moons/overview/
