Ron Taam Professor Emeritus

Ronald Taam's primary research interests are in the area of astrophysical hydrodynamics of gas flows, close binary systems, accretion disks, nature of x-ray bursts, and in the area of stellar dynamics as related to the secular evolution of galaxies.  In particular, he studies the ignition and propagation of nuclear burning fronts in stars, the structure and evolution of accretion disks surrounding compact stars (stellar mass and supermassive black holes), the evolution of close double-star systems, and the formation and evolution of structures in galaxies.  Taam's recent research accomplishments in stellar astrophysics have included a systematic study of the three-dimensional hydrodynamic interaction of two stars in a close binary system.  In addition, he has also investigated the nature of the spiral/ring-like structures observed in the circumstellar envelopes of asymptotic giant branch stars. On the extragalactic scale, he has investigated a two component model for the accretion flow onto supermassive black holes in active galactic nuclei and has investigated the formation and evolution of stellar bars in galaxies, important for the gas fueling of active galactic nuclei.
