Photometric and spectroscopic variability of the blue supergiant rho Leo
V. A. Checha, A. Aret, I. Kolka +12
Context. The post-main-sequence evolution of massive stars remains poorly understood, particularly for blue supergiants. These objects play a crucial role in the dynamical and chem…
Discrimination of metric theories
F. J. Lobo, M. Rivera-Tapia, G. Rubilar +2
We study the possibility of discriminating between metric theories within the Parametrized Post-Newtonian formalism. In this approach, the two-dimensional quantum state of a massiv…
Studying stellar populations in Omega Centauri with phylogenetics
P. Jofré, C. Aguilera-Gómez, P. Villarreal +14
The nature and formation history of our Galaxy's largest and most enigmatic stellar cluster, known as Omega Centauri (ocen) remains debated. Here, we offer a novel approach to dise…
Internal symmetry to the rescue: well-posed 1+1 evolution of self-interacting vector fields
Gabriel Gomez, Jose F. Rodriguez
Previous studies have identified potential instabilities in self-interacting vector theories associated with the breakdown of the well-posedness of the initial-value problem. Howev…
Coherence based on positive operator-valued measures for standard and concatenated quantum state discrimination with inconclusive results
L. F. Melo, O. Jiménez, L. Neves
The optimal measurement that discriminates nonorthogonal quantum states with fixed rates of inconclusive outcomes (FRIO) can be decomposed into an assisted separation of the inputs…
Dynamical Shortcomings in the Generalized SU(2) Proca Theory: Challenges for Cosmic Acceleration
Santiago Garcia-Serna, J. Bayron Orjuela-Quintana, Yeinzon Rodriguez +2
The Generalized SU(2) Proca (GSU2P) theory has recently garnered attention for its potential to describe key phases of cosmic evolution, including primordial inflation and late-tim…
