Taeil Bai

Biography

Taeil Bai was born in Korea on July 16, 1945. Bai received his B.S. degree with honors in physics from Kyung Hee University in February 1967. He served in the Korean army as a lieutenant from 1967 through 1969, and worked as a Teaching Assistant at Kyung Hee University from 1970 to 1972.

Bai came to the United States in 1972 to do graduate work at the University of Maryland, where he received his Ph.D. in May 1977. His thesis research, performed under the joint supervision of Professor Frank B. McDonald and Dr. Reuven Ramaty, was on high-energy phenomena of solar flares.

From 1977 to 1978, Dr. Bai worked at Goddard Space Flight Center, primarily with Dr. Ramaty. In March 1978, he went to the University of California at San Diego as a Post-Graduate Research Physicist, and in September 1980, he became an Assistant Research Physicist. At UCSD, he worked mainly with Dr. Hugh S. Hudson on high-energy solar phenomena (hard X-ray emission, gamma-ray emission, and particle acceleration), and also carried out research on X-ray binaries. Dr. Bai received the first Donald E. Billings Award of the University of Colorado in 1978.

In September 1982, Dr. Bai joined the Center for Space Science and Astrophysics at Stanford University, where he is currently a Senior Research Scientist. Analyzing MDI data, he has been studying plasma flows in active regions.

Dr. Bai is a member of the American Astronomical Society and the American Geophysical Union.

Jørgen Christensen-Dalsgaard

Biographical sketch:

Christensen-Dalsgaard received his M.Sc. degree from Aarhus University, Denmark, in 1975, and his Ph.D. in astrophysics from Cambridge University in 1978. After postdoctoral periods at Institut d'Astrophysique, Liege, National Center for Atmospheric Research, Boulder, and NORDITA, Copenhagen, he returned to the Institute of Physics and Astronomy, Aarhus University, where he has been since 1984, from 1996 as Research Professor in Helio- and Asteroseismology. Since 1994 he has in addition been associate director of the Theoretical Astrophysics Center under the Danish National Research Foundation. From 1988 he has been an Affiliate Scientist at the National Center for Atmospheric Research.

Main areas of research:

Christensen-Dalsgaard's research activities have been concerned with various aspects of the structure of solar and stellar interiors, and of helioseismic and asteroseismic investigations of the properties of the Sun and other stars. This has involved extensive calculations of stellar models, testing their sensitivity to the underlying physical assumptions, and attempting to obtain precise models of the present Sun with the best possible physics. Furthermore, Christensen-Dalsgaard has taken part in the development and testing of methods for helioseismic inversion and has applied these methods to infer the structure and rotation of the solar interior.

Other professional activities:

Christensen-Dalsgaard is a member of the Danish Natural Science Research Council, vice chairman of the Danish Space Board, and member of the Board of the Nordic Optical Telescope. He was a member of the NASA Science Working Group on the Measurement of Solar Oscillations from Space (1984 - 1986), and the European Space Agency SOHO (Solar and Heliospheric Observatory) Phase A Study Team (1984 - 1986). He was a member of the European Southern Observatory Scientific and Technical Committee (1988 - 1992). Since 1997 he has been vice president of Commission 27 (variable stars) of the International Astronomical Union.

Michael J. Thompson

Biographical sketch

Thompson received his B.A. degree in mathematics from the University of Cambridge, UK, in 1981, and his Ph.D. in astrophysics (also from Cambridge) in 1988. Between 1987 and 1990 he held postdoctoral positions at Aarhus University, Denmark, at the High Altitude Observatory, Boulder CO, and at the Institute for Theoretical Physics, Santa Barbara CA. Since 1990 he has been in the Astronomy Unit, Queen Mary & Westfield College, University of London, UK, as a Lecturer and more recently as Reader in Mathematics and Astronomy.

Main areas of research

Thompson's main research interests are in the structure and dynamics of the interior of the Sun and other stars, and in helio- and asteroseismology. His early work was on the effect of rotation and magnetic fields on stellar oscillations, and this continues to be a major interest, together with using oscillation data to constrain the rotation and magnetic fields of stellar interiors. Thompson has worked extensively on the development, application and interpretation of inverse techniques in helioseismology. Major applications have been to studying the hydrostatic structure of the Sun and its internal rotation.

Other professional activities

Thompson is an Associate Investigator on SOI-MDI on the SOHO satellite, and co-leader with J. Toomre of the Internal Rotation team in that project. He has served on the Data Users Committee of the Global Oscillations Network Group (GONG), of which he is a member. He is on the editorial board of Astronomical \& Astrophysical Transactions; a member of the International Astronomical Union and of the European Astronomical Society; and a Fellow of the Royal Astronomical Society. He is currently, with D. Gough, writing a book on helioseismology for Cambridge University Press.

Juri Toomre

Biographical Sketch:

Toomre received B.Sc. and M.Sc. degrees from the Massachusetts Institute of Technology in aeronautics and astronautics in 1963, and then went to England as a Marshall Scholar to receive a Ph.D. from Trinity College, University of Cambridge in applied mathematics in 1967. Since 1975 Toomre has been a professor of astrophysics in the Department of Astrophysical and Planetary Sciences, and a fellow of the Joint Institute for Laboratory Astrophysics (JILA), University of Colorado, Boulder.

Main Research Areas:

Toomre's research and teaching centers on astrophysical fluid dynamics (AFD), with particular emphasis on nonlinear theories for compressible convection in stars, and in studying nonlinear dynamical systems exhibiting multiple bifurcations and chaos. Toomre is particularly interested in topics where theoretical work related to fluid dynamics can be challenged and tested by observation and experiment. He is active in turbulence theory and simulation, with extensive experience in the use of vector supercomputers, massively parallel machines, high-speed networks, archival storage systems, and major visualization systems. Toomre has sustained interests in helioseismology, using observations of the frequency-splitting of five-minute oscillations of the sun to search for subphotospheric flows, large-scale structures and differential rotation in the convection zone; inverse theory has been developed to interpret the data. Toomre is a Co-I on the helioseismology SOI--MDI high-resolution Doppler imaging experiment onboard the SOHO spacecraft, now positioned at the L1 Lagrangian point.

Professional Activities:

Toomre has been on the board of directors of AURA (Association of Universities for Research in Astronomy, operating the National Optical Astronomy Observatories). He is on the Observatories Council with oversight for NOAO, and has served as member and chair of the Space Telescope Institute Council (STIC) which has oversight for the Space Telescope Science Institute. Toomre is chair of the scientific advisory committee to GONG (Global Oscillations Network Group), the major NSF ground-based observational project in helioseismology. He is co-leader of the dynamics and inversion team of GONG, and co-leader of the rotation inversion team on SOI--MDI.
