Splinter meeting HOT
Magnetic fields in hot stars
Conveners: Swetlana Hubrig, Klaus Reinsch
The study of
stellar magnetic fields and their role in stellar
evolution is of special astrophysical significance,
because their presence is related to phenomena with temporal coverage
from the re-ionization of the early
universe to the final stages of stars.
It is widely recognized that magnetic fields influence the evolution
of stars, and determine their fate in the form
of magnetized white dwarfs or neutron stars, depending on the initial
stellar mass. The aim of the proposed splinter meeting is to greatly
establish a firm basis of our observational knowledge of stellar
surface magnetic fields with the emphasis on
magnetic fields in hot stars, including upper main sequence stars and
the end products: white dwarfs, neutron stars, and magnetars.
The results of the pioneering work done during the last decade with
significant new discoveries has greatly inspired the design and
construction of sensitive instrumentation, in the form of low and
high-resolution spectro-polarimeters mounted on large aperture
telescopes. This new generation of instruments is about to be
available, and will allow a major improvement in our knowledge of
surface stellar magnetic fields.
