The Decline and Fall of ROME. V. A Preliminary Search for Star-disrupted Planet Interactions and Coronal Activity at 5 GHz among White Dwarfs within 25 pc

The Astrophysical Journal
The recent discovery of planetesimals orbiting white dwarfs has renewed interest in the final chapters of the evolution of planetary systems. Although observational and theoretical studies have examined the dynamical evolution of these systems, studies ...

Physically consistent mesoscale model evaluation in complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a novel approach for evaluating mesoscale atmospheric models in complex terrain by selecting physically consistent grid points and applying height‐based corrections. The method corrects for sensor height and terrain elevation differences between model and observations using a time‐varying lapse rate.

How to rule out (g − 2) μ in U 1 L μ − L τ $$ \textrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ with white dwarf cooling

Journal of High Energy Physics
In recent years, the gauge group U 1 L μ − L τ $$ \textrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ has received a lot of attention since it can, in principle, account for the observed excess in the anomalous muon magnetic moment (g − 2) μ , as well as the ...

Loss Behavior in Supervised Learning With Entangled States

Advanced Quantum Technologies, EarlyView.
Entanglement in training samples supports quantum supervised learning algorithm in obtaining solutions of low generalization error. Using analytical as well as numerical methods, this work shows that the positive effect of entanglement on model after training has negative consequences for the trainability of the model itself, while showing the ...

Shocking and Mass Loss of Compact Donor Stars in Type Ia Supernovae

The Astrophysical Journal
Type Ia supernovae arise from thermonuclear explosions of white dwarfs accreting from a binary companion. Following the explosion, the surviving donor star leaves at roughly its orbital velocity.
