Red giant masses and ages derived from carbon and nitrogen abundances, Spectroscopic determination of masses for red giants, Young alpha-enriched giant stars in the solar neighborhood, and Dynamical heating across the Milky Way disc.
Prof. Marc Pinsonneault is a theorist on the structure and evolution of stars at Ohio State University. His research interests range from the microphysics of stellar models, including composition, energy, and angular momentum transport mechanisms, to the observed properties of stars. An element of his current research is the use of astroseismological data from the Kepler space mission, in combination with APOGEE and other spectroscopic surveys, to obtain novel constraints on stellar physics, stellar populations, and the chemical evolution of the Milky Way.
