This is the exciting part: #KHI can mix magnetized and non-magnetized #plasma, drive #turbulence, transport mass/energy/momentum/ #MagneticFlux, and may contribute to small-scale #magnetic braiding, thus one route by which free #MagneticEnergy is built up in the solar #atmosphere.

That makes them relevant to the long-standing puzzle of why the #corona is heated to millions of kelvin while the visible surface is only ~5,800 K. 😎🔥

For the first time, #KelvinHelmholtzInstabilities 🌀 have been directly observed in the #Sun’s #photosphere ☀️🔭

#DKIST images reveal tiny #vortex-like structures at the edges of #MagneticFlux concentrations. #MHD simulations reproduce them and show that shear flows along these #magnetic boundaries trigger the instability.

Weekly Update from the Open Journal of Astrophysics 04/07/2026

It’s Saturday again so it’s time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further seven papers, bringing the number in Volume 9 (2026) to 136 and the total so far published by OJAp up to 584.

I will continue to include the posts made on our Mastodon account (on Fediscience); these announcements also show the DOI for each paper.

The first paper to report this week, published on Monday 29th June, is “Analysis and implications of the spatio-spectral morphology of the Fermi Bubbles” by Ami Tank (Indian Institute of Technology) and Roland Crocker & Mark R. Krumholz (Australian National University). Published in the folder High-Energy Astrophysical Phenomena, this paper presents an analysis of the gamma-ray structures of Fermi Bubbles in the Milky Way using a decade of data. The research suggests either hadronic or leptonic processes can explain the data.

The overlay for this paper is here

The second paper for this week, also published on Monday 29th June, but in the folder Cosmology and Nongalactic Astrophysics, is “A first measurement of baryonic feedback with Fast Radio Bursts” by Robert Reischke (Universität Bonn, Germany) and Steffen Hagstotz (Ludwig-Maximilians Universität München, Germany). This paper argues that Fast Radio Bursts (FRBs) provide a new method to trace baryon distribution and feedback in the cosmos, offering insights into matter distribution and rejecting no-feedback scenarios with high confidence.

The overlay looks like this:

The third paper of the week, published on Tuesday 30th June in the folder High-Energy Astrophysical Phenomena, is “Idealized Global Models of Accretion Disks with Strong Toroidal Magnetic Fields” by Minghao Guo & Eliot Quataert (Princeton U., USA), Jonathan Squire (U. Otago, NZ), Philip F. Hopkins (Caltech, USA) and James M. Stone (Princeton). This study uses global magnetohydrodynamic simulations to explore the behavior of idealized accretion disks with strong toroidal magnetic fields, finding that these systems maintain a moderately strong mean azimuthal field.

The fourth paper of the week, published on Tuesday 30th June in the folder High-Energy Astrophysical Phenomena, is “On the effective spin-mass ratio relation of binary black hole mergers that evolved in isolation” by Sambaran Banerjee (Helmholtz-Instituts für Strahlen und Kernphysik, Germany) and Aleksandra Olejak (MPA Garching, Germany). This study explores mechanisms of binary black hole mergers and finds that certain spin and mass ratio trends can be naturally explained by isolated binary evolution. The overlay for this one is here:

The fifth paper of the week, also published on Tuesday 30th June but in the folder Solar and Stellar Astrophysics is “A systematic survey for hypervelocity runaways from thermonuclear supernovae” by Kareem El-Badry (Caltech, USA), and 18 others based in the USA, Germany, Austria and the UK. This paper presents a systematic survey of hypervelocity runaways, resulting from white dwarf explosions in binary systems. The findings suggest a diversity of remnant masses, ages, and heating mechanisms, challenging theoretical models.

The sixth and penultimate paper of this week is “Boris and Exponential Integrators in the Theory of Particles Interacting with Magnetic Turbulence” by Andreas Shalchi (U. Manitoba, Canada). This was published on Wednesday 1st July, in the folder Solar and Stellar Astrophysics (it is posted in the plasma physics section of aXiv but cross-listed in solar and stellar astrophysics). The study compares the Rodrigues and Boris integrators in test-particle simulations of charged particles interacting with magnetic fields, finding both methods yield similar results.

The seventh and final paper for this week is “Inflation at the End of 2025: Constraints on $r$ and $n_S$ using the Latest CMB and BAO Data” by Lennart Balkenhol (Institut d’Astrophysique de Paris, France) and 12 others based in France, Italy, Switzerland, UK, USA and Australia. This was also published on Wednesday 1st July, in the folder Cosmology and Nongalactic Astrophysics. This study presents constraints on parameters of inflationary models in cosmology, using the latest cosmic microwave background and baryon acoustic oscillation data. The findings help differentiate between inflation models.

And that concludes this week’s update. We’re starting to catch up on the backlog generated in June. At just past the halfway point of the year, which is where we are, we’re on 136 papers, which suggests a total around 272 for the year.

⚛️ What does it actually take to make fusion energy work?
Temperatures above 150 million degrees Celsius. Sufficient plasma density. Long enough confinement time. All simultaneously. ITER uses a tokamak and powerful magnetic fields to achieve exactly that.
A fusion reaction releases nearly four million times more energy than burning fossil fuels.

Helion Energy Is Building A Fusion Power Plant. Can Its Technology Deliver?

In the same way, the stellarator in the Wendelstein 7-X fusion facility confines plasmas - except that in Wendelstein 7-X, 50 non-planar and 20 planar superconducting coils hold plasmas with temperatures of up to 30 million degrees Celsius in place. 🤯 #Wendelstein7x #Plasmaphysics #MaxPlanckInstitute

This tabletop stellarator
@plasmaphysik in Greifswald demonstrates to visitors how magnetic fields confine plasmas. Two parallel coils outside the vacuum chamber & two intertwined, water-cooled coils inside keep the visible low-temperature plasma stably in place. Each pair of coils has its own power supply for independent control—allowing visitors to test how a plasma can be stabilized most effectively / Picture: Paolo Verzone

Vera Chernogorova – Conversations About The Atomic Nucleus (Eureka Series)

The book discusses issues related to the study of the atomic nucleus and its structure, nuclear forces, and the components of the nucleus. It also describes the achievements of Soviet scientists in the field of nuclear energy.

About the Author

After graduating from the Faculty of Physics and Mathematics at university, Vera Aleksandrovna entered postgraduate studies and later became a research fellow at the Joint Institute for Nuclear Research in the town of Dubna. For nearly twelve years, she participated in experiments conducted on a particle accelerator — the synchrocyclotron. Vera Aleksandrovna is a co-author of many scientifi c papers on the study of the properties of mu-mesons.

In recent years, she has published over ten articles in journals such as Znanie — Sila (Knowledge Is Power), Science and Life, Technology for the Youth, and others.

The topics of these articles include problems in nuclear physics, high-energy physics, astrophysics, controlled thermonuclear fusion, the application of scientific achievements in The human practice, and the future of science. Many of these articles have been reprinted in foreign journals.

In 1973, our publishing house released her book Mysteries of the Microworld, which discussed some current problems in the physics of elementary particles. Conversations About the Atomic Nucleus is the author’s second book to appear in the Eureka series.
