A solution to the tension of burning on neutron stars and nuclear physics
When neutron stars accrete matter from a companion star, this matter forms a disc around them and eventually falls on their surface. Here, the fuel can ignite into bright flashes called Type I bursts. Theoretical calculations based on state-of-the-art nuclear reactions are able to explain many features of the bursts. However, models predict that the bursts should cease at high accretion rates, whereas in many sources they disappear at much lower rates. Moreover, their recurrence times also show…

Global ocean acidification has passed safe planetary boundary threshold: Study
A new assessment finds that the world’s oceans crossed the safe threshold for acidification in 2020, breaching a key planetary boundary and posing serious threats to marine life. Ocean acidification is caused when excess atmospheric carbon dioxide, resulting from human activities like burning fossil fuels, dissolves in seawater, forming carbonic acid that increases the water’s […]

A Multiscale Eulerian Vlasov-Rosenbluth-Fokker-Planck Algorithm for Thermonuclear Burning Plasmas
Accurate treatment of energetic fusion byproducts in laboratory plasmas often requires a kinetic description, owing to their large birth kinetic energy and long mean-free-paths compared with the characteristic system scale lengths. For example, alpha particles produced by deuterium--tritium fusion reactions are born at high energies (\SI{3.5}{MeV}) and predominantly slow down through interactions with electrons traveling at comparable speeds. As an alpha particle slows, its distribution collaps…

AstroSat/UVIT Study of NGC 663: first detection of Be+sdOB systems in a young star cluster
Context. Be stars are rapidly rotating stars surrounded by a disc; however, the origin of these remains unclear. Mass and angular momentum transfer in close binaries account for the rapid rotation of a major fraction of Be stars, supported by the previous detection of low-mass stripped companions to them. The stripped companions can be helium burning subdwarf OB-type stars (sdOBs), and white dwarfs (WDs). Aims. The main objective of this study is to characterise the identified Be stars in the y…

Particle-in-Cell Simulations of Burning ICF Capsule Implosions
Anomalies observed in the neutron spectral shift of high-yield shots at the National Ignition Facility (NIF) suggest the presence of suprathermal ions, implying that kinetic effects play a significant role in burning inertial confinement fusion (ICF) plasmas. Furthermore, recent measurements of reaction-in-flight (RIF) neutrons offer a direct probe of the stopping power in the burning fuel region of high energy alpha particles and up-scattered fuel ions. We have developed the particle-in-cell c…

Calamus 14 Not heat flames up and consumes
A declaration of love, eroticism mixed with nature imagery. Something of a theme in Calamus! It didn't really grab me though, I think because so many of the lines start with negations and it distances me from the meaning.
The sexy line here:
the flames of me, consuming, burning for his love whom I love!
I also like the imagery of seeds wafted in the wind, then heading to "my Soul is borne through the open air".

Blue Stragglers prefer peaceful environments because binaries do the same
Blue straggler stars (BSSs) are core hydrogen-burning stars routinely observed in resolved stellar systems. According to the theory of single star evolution they should not exist because, due to their large mass, they should have already evolved to stellar remnants. Hence, they are suspected to be the result of mass-enhancement processes, like mass-transfer activity in binary systems, mergers in binary or higher order systems, or direct stellar collisions, possibly mediated by dynamical interac…

Complexity of Firefighting on Graphs
We consider a pursuit-evasion game that describes the process of extinguishing a fire burning on the nodes of an undirected graph. We denote the minimum number of firefighters required by $\text{ffn}(G)$ and provide a characterization for the graphs with $\text{ffn}(G)=1$ and $\text{ffn}(G)=2$ as well as almost sharp bounds for complete binary trees. We show that deciding whether $\text{ffn}(G) \leq m$ for given $G$ and $m$ is NP-hard. Furthermore, we show that shortest strategies can have supe…

Why Do Stars Turn Red? II. Solutions of Steady-State Stellar Structure
To investigate the physical origin of red giants (RGs) and red supergiants (RSGs), we construct steady-state models of stellar envelopes by explicitly solving the stellar structure equations, with boundary conditions set at the stellar surface and the hydrogen burning shell. For comparison, we consider both polytropic and realistic models. Polytropic models adopt a polytropic equation of state (EOS) and neglect energy transport, while realistic models incorporate radiative and convective energy…

I'm reading The Lost Princess by #GeorgeMacDonald and in one paragraph he starts off by saying that there is a fire made of fir-wood and by the end of the paragraph refers to it as a peat fire.
#ChatGPT informs me that fir-wood is fast burning and was often used in #Scotland to get a fire started while peat was long-burning and thus would be added to the fire thereafter.
It seems logical, but ChatGPT has also struggled to provide me with clear references to this information.
Curious if anyone is familiar with whether this was/is so? I'd like something to depend upon beyond the words of generative AI. 😂

Implications of a turbulent convection model for classical Cepheids
The appearance of blue loops in the evolutionary tracks of intermediate-mass core He-burning stars is essential for explaining the observed characteristics of Cepheids. The blue loops for lower mass Cepheids cannot always be reproduced when only classical, local mixing length theory (MLT) is used. Additionally, classical models result in a mass discrepancy compared to pulsational and dynamical mass determinations. Both problems can be resolved through an ad-hoc extension of the MLT for convecti…

On miniature ultra-high-field commercial stellarator reactors with breeding external to resistive coils
The working parameters and challenges of transposed (breeding external to resistive coils) ultra-high-field pulsed commercial stellarator reactors of small plasma volume are studied. They may allow production of commercial heat and electricity in a tiny and simple device, and contribute to the knowledge on burning plasmas. The concept is based on the previous works (V. Queral et al.) performed for the high-field experimental fusion reactor i-ASTER (J. Fus. Energy 37 2018) and the recent Distrib…
