T h o m a s R i m m e l e Site Director National Solar Observatory, Sacramento Peak
My name is Thomas Rimmele and I am the Site Director at NSO's Sacramento Peak
Observatory. My scientific work is focused on understanding the basic physics of
astrophysical processes that can be studied in a unique way on the Sun. Examples are:
How does stellar convection work and how are magnetic fields generated by convective
motions? How does a sunspot work? How are solar oscillations generated? What sets off a
flare? Why is the solar corona as hot as it is (a few million degrees K)? There is a lot
of advanced physics involved in all of this and if I didn't know it back then I now
understand what the broad physics and math training I received at high school and at the
University was good for.
To find the answers to these questions we need to observe the Sun at very high
resolution. Building the instruments that allow us to obtain high resolution observations
is quite a challenge. I love to work on challenging projects so I spend a lot of time on
developing new instrumentation like adaptive optics.
Being able to observe, for example, a sunspot at a resolution that has never been
achieved before is a very exciting experience.
I am also involved in the Solar-B mission (the Japanese-US spacecraft which will
follow up on Yohkoh), which will be launched in 2004.
