Searching for a link between the magnetic nature and other observed properties of Herbig Ae/Be stars

TL;DR

This study investigates magnetic fields in Herbig Ae/Be and debris disk stars to identify correlations with stellar properties, accretion, disk features, companions, age, and X-ray emission, aiming to understand their magnetic nature.

Contribution

It provides new magnetic field survey data for Herbig Ae/Be and debris disk stars and explores potential correlations with various stellar and disk properties.

Findings

No clear correlation between magnetic fields and disk inclination.

Magnetic properties show no strong link with age or X-ray emission.

Results suggest magnetic fields may not be directly related to accretion or disk features.

Abstract

We present the results of a new magnetic field survey of Herbig Ae/Be and A debris disk stars. They are used to determine whether magnetic field properties in these stars are correlated with the mass-accretion rate, disk inclinations, companion(s), Silicates, PAHs, or show a more general correlation with age and X-ray emission as expected for the decay of a remnant dynamo.
