Stellar structure and evolution
Bruce Carney
Chris Clemens
Bruce Carney studies the Galaxy's oldest stars, including
binary orbits and what they reveal about the stars' ages
and evolution, the chemical abundance patterns and what
they reveal about the earliest stages of nucleosynthesis
in the Galaxy, and on pulsating stars that are often
used as "standard candles" to determine distances to
star clusters and other galaxies.
Chris Clemens primarily studies the self-excited resonant oscillations of
stars or "starquakes". Through high precision monitoring of a star's
brightness and surface velocities, he studies the interior properties using
methods analogous to terrestrial seismology. His work in this area has
focused on the compact stellar remnants known as white dwarf stars.
He also studies low mass binary stars, both interacting and non-interacting,
to measure basic stellar properties with high precision.
