Office Hours: I will typically be around Queen's on the day
of the class at QUB, and available at Armagh Observatory at least two
or three days most weeks. Feel free to talk with me any time you see me, or e-mail
me to make an appointment.
This course will provide an overview of some of what is now known
about the presence of magnetic fields in stars. It will cover both
observational and theoretical aspects of the subject, including
spectropolarimetric methods of detecting stellar fields,
chariacteristics of stars in which magnetic fields are found, the
use of the Stokes vector as a description of polarisation signals,
spectrum synthesis and modelling as methods of analysing
observations, and a discussion of the significance of magnetic
fields in stellar evolution. You may download
a more detailed outline
here.
Exercises: I think that doing a number of exercises and problems
is a really essential part of understanding a subject. It will make
the hours you are putting into coming to lectures and reading far
more valuable, and greatly increase your understanding of the
subject. I have provided a large number of small (and hopefully
fairly easy) practice problems that are closely linked to the
material of the lectures. If you can do them easily, you understand
the material pretty well. If you find them hard, it is particulalry
important for you to tackle them, or much of your time attending
will have been wasted. We can discuss any of the problems after
classes or individually, as people prefer.
Download these exercises here. Note that the problem material is
not finished; it will be updated from time to time.
