BGRem: A background noise remover for astronomical images based on a diffusion model
Rodney Nicolaas, Sascha Caron, Fiorenzo Stoppa +4
Context: Astronomical imaging aims to maximize signal capture while minimizing noise. Enhancing the signal-to-noise ratio directly on detectors is difficult and expensive, leading…

Understanding the Drag Torque in Common Envelope Evolution
Soumik Bhattacharyya, Luke Chamandy, Eric G. Blackman +2
Common envelope (CE) evolution is largely governed by the drag torque applied on the in-spiralling stellar components by the envelope. Previous work has shown that idealized models…

The birth of Be star disks I. From localized ejection to circularization
J. Labadie-Bartz, A. C. Carciofi, A. C. Rubio +35
Classical Be stars are well known to eject mass, but the details governing the initial distribution and evolution of this matter into a disk are poorly constrained by observations.…
