Evolution of Stellar Magnetic Fields [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractStellar magnetic fields can reliably be characterized by several magnetic activity indicators, such as X-ray or radio luminosity. Physical processes leading to such emission provide important information on dynamic processes in stellar atmospheres and magnetic structuring.

Magnetic Field Generation in Stars [PDF]

, 2015
Enormous progress has been made on observing stellar magnetism in stars from the main sequence through to compact objects. Recent data have thrown into sharper relief the vexed question of the origin of stellar magnetic fields, which remains one of the ...

Predicting Epileptogenic Tubers in Patients With Tuberous Sclerosis Complex Using a Fusion Model Integrating Lesion Network Mapping and Machine Learning

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate localization of epileptogenic tubers (ETs) in patients with tuberous sclerosis complex (TSC) is essential but challenging, as these tubers lack distinct pathological or genetic markers to differentiate them from other cortical tubers.

Starspot Area Coverage: Correlation with Age and Spectral Type in FGK and M Stars

The Astrophysical Journal Letters
Starspots, analogous to sunspots, are surface manifestations of stellar magnetic activity. Their study provides crucial insights into stellar dynamo processes and the evolution of magnetic phenomena.

Many Aspects of Magnetic Fields in Neutron Stars

Universe, 2018
In this work, we explore different aspects in which strong magnetic fields play a role in the composition, structure and evolution of neutron stars. More specifically, we discuss (i) how strong magnetic fields change the equation of state of dense matter,

Stellar dynamics: Rotation, convection, and magnetic fields [PDF]

, 2015
Stars are changing entities in a constant evolution during their lives. At non-secular time scales (from seconds to years) the effect of dynamical processes such as convection, rotation, and magnetic fields can modify the stellar oscillations. Convection excites acoustic modes in solar-like stars, while rotation and magnetic fields can perturb the ...

ALS With and Without Upper Motor Neuron Signs: A Comparative Study Supporting the Gold Coast Criteria

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The Gold Coast criteria permit diagnosis of amyotrophic lateral sclerosis (ALS) even without upper motor neuron (UMN) signs. However, whether ALS patients with UMN signs (ALSwUMN) and those without (ALSwoUMN) share similar characteristics and prognoses remains unclear.

Characterising the magnetospheric accretion process of DF Tauri’s primary

Astronomy & Astrophysics
Context. The accretion process in young stellar objects (YSOs) is fundamental to the formation of stellar systems. This process governs the star’s mass assembly, the transfer of angular momentum, and the shaping of the protoplanetary disc, thereby ...

HD 158450: A MAGNETIC CHEMICALLY PECULIAR STAR IN A YOUNG STELLAR GROUP

Odessa Astronomical Publications, 2008
We report on the discovery of the Zeeman resolved spectral lines, corresponding to the very large magnetic field modulus [H] = 11.1 kG, in the spectrum of the chemically peculiar star HD 158450 belonging to the recently discovered Mamajek 2 stellar group.
