AAS Honors Distinguished Astronomers with 2012 Prizes


At its 219th semiannual meeting last week in Austin, Texas, the American Astronomical Society (AAS) named the recipients of its 2012 prizes for achievements in research, instrument development, education, and writing.

The Society’s prestigious Henry Norris Russell Lectureship goes to W. David Arnett (University of Arizona) “for a lifetime of seminal contributions to the fields of stellar explosions, nuclear astrophysics, and hydrodynamics.” Arnett has been a leader in developing our understanding of core-collapse processes and the fusion of new elements in massive stars. He has also done pioneering work on thermonuclear burning in white-dwarf stars and on the origin of Type Ia supernovae, which are at the center of contemporary observational cosmology.

The Newton Lacy Pierce Prize for outstanding achievement in observational research by an early-career astronomer goes to John A. Johnson (Caltech) “for major contributions to understanding fundamental relationships between extrasolar planets and their parent stars.” Johnson has found that planetary orbits can be tipped at a wide variety of angles with respect to their host stars’ spin axes. His work has also elucidated possible correlations between planet frequency and stellar mass and composition.
