Tootfinder

An interesting, very Swiss perspective on the Humane AI pin: you won't be able to buy it in Switzerland, or even get it shipped here, since the purchase and ownership of lasers of Class 2 or higher (according to MKBHD, minute 03:07) is strictly forbidden (and you could be fined up to 40'000 Swiss Francs).
(BTW, didn't you know that? Check your presenter laser pointer if you live within the borders of Helvetia… you might want to recycle it asap.)

JWST Discovery of $40+$ Microlensed Stars in a Magnified Galaxy, the "Dragon" behind Abell 370
Strong gravitational magnification by massive galaxy clusters enable us to detect faint background sources, resolve their detailed internal structures, and in the most extreme cases identify and study individual stars in distant galaxies. Highly magnified individual stars allow for a wide range of applications, including studies of stellar populations in distant galaxies and constraining small-scale dark matter structures. However, these applications have been hampered by the small number of ev…

Frozen boson stars in an infinite tower of higher-derivative gravity
In this paper, we present a solution for a five-dimensional boson star under gravity with infinite tower of higher curvature corrections. We discover that when the coupling constant exceeds a certain threshold, an alternative configuration emerges, distinct from the conventional five-dimensional boson star. This new structure is characterized by a broader frequency range, with its minimum value approaching zero. At a truncation of $n=2$ for the correction order, the solution and its scalar curv…

Exploring the borderline between stable mass transfer and mergers in close binary evolution

Exploring the borderline between stable mass transfer and mergers in close binary evolution
The majority of massive stars reside in binary systems, which are expected to experience mass transfer during their evolution. However, so far the conditions under which mass transfer leads to a common envelope, and thus possibly to a merging of both stars, are not well understood. Main uncertainties arise from the possible swelling of the mass gainer, and from angular momentum loss from the binary system, during non-conservative mass transfer. We have computed a dense grid of detailed models o…

Residue Structures
We consider residue structures $R/G$ where $(G,+)$ is an additive subgroup of a ring $(R,+,\cdot)$, not necessarily an ideal. Special instances include Krasner's construction of quotient hyperfields, and Pumpluen's construction of nonassociative algebras. The residue construction, treated formally, satisfies the Noether isomorphism theorems, and also is cast in a broader categorical setting which includes categorical products, sums, and tensor products.
