Physical properties and the maximum compactness bound of a class of compact stars in gravity
Arpita Ghosh, Abhishek Paul, Ranjan Sharma +1
Motivation: Motivated by the growing interest in understanding the role of non-metricity in describing dense stellar systems, in this paper, we study compact stellar configurations…

Detecting and characterising the magnetic field of exoplanets
A. Strugarek, S. V. Berdyugina, V. Bourrier +25
Magnetic fields play a crucial role in planetary evolution and habitability. While the intrinsic magnetic fields of solar system planets are relatively well understood, the magneti…

Ohmic heating in the upper atmosphere of hot exoplanets The influence of a time-varying magnetic field
A. Strugarek, A. GarcÃa Muñoz, A. S. Brun +1
Exoplanets on close-in orbit are subject to intense X-ray and ultraviolet (XUV) irradiation from their star. Their atmosphere therefore heats up, sometimes to the point where it th…
