Localizing flares to understand stellar magnetic fields and space weather in exo‐systems
Astronomische Nachrichten, Volume 343, Issue 4, May 2022., 2022 Abstract Stars are uniform spheres, but only to first order. The way in which stellar rotation and magnetism break this symmetry places important observational constraints on stellar magnetic fields, and factors in the assessment of the impact of stellar activity on exoplanet atmospheres.

Asteroseismology and interferometry [PDF]
The Astronomy and Astrophysics Review, 2007 Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies of solar-like pulsators, have boosted the impact of this field of research within Astrophysics and have led to a significant increase in the size of the research community ...

Detection and Optimization of Traffic Networks Based on Voronoi Diagram
Discrete Dynamics in Nature and Society, Volume 2021, Issue 1, 2021., 2021 Traffic peak is an important parameter of modern transport systems. It can be used to calculate the indices of road congestion, which has become a common problem worldwide. With accurate information about traffic peaks, transportation administrators can make better decisions to optimize the traffic networks and therefore enhance the performance of ...

The potential of Shannon entropy to find the large separation of δ Scuti stars: The entropy spectrum
Frontiers in Astronomy and Space Sciences, 2022 This study explores the use of Shannon entropy to find periodic patterns in the oscillation spectra of δ Scuti stars. We have developed a new diagnostic tool for detecting potential patterns that scans for minimal entropic states in the well-known ...

White-dwarf asteroseismology: an update [PDF]
, 2020 The vast majority of stars that populate the Universe will end their evolution as white-dwarf stars. Applications of white dwarfs include cosmochronology, evolution of planetary systems, and also as laboratories to study non-standard physics and ...

On the Detectability of Large-Scale Flows by Asteroseismology
Frontiers in Astronomy and Space Sciences, 2020 Large-scale convective motions are an integral part of stellar interior dynamics and might play a relevant role in stellar dynamo processes. However, they are difficult to detect or characterize.
