of Physics Aileen A. O'Donoghue is among the scientists who have been
at work on an extensive survey of stellar activity in nearby solar-type
stars, the results of which were reported at the recent meeting of
the American Astronomical Society. This report is of special interest,
as it may provide information about the behavior of the sun in both
the past and the future.
Also listed as a researcher in the survey is
2003 physics graduate Emily R. Knox, of Fairport, New York.
of astronomers has been engaged in a NASA/Jet Propulsion Laboratory
at the California Institute of Technology-funded three-year project
obtaining spectroscopic data for the nearly 3,600 sun-like stars within
130 light-years of the sun. The purposes of thes project are to provide
new, precise classifications of these stars; to derive the basic physical
characteristics of these stars, such as temperatures, evolutionary
states and overall elemental abundances; and to provide a "snapshot" of
the stellar activity of these stars.
The report states that the team
is "more than halfway to our goal of measuring
the stellar activity in our 3,600-star sample."
O'Donoghue recently was named
Colorado Mountain College Alumnus of the Year. She earned her associate's
degree from Colorado Mountain College in 1978, and has been a member
of the St. Lawrence faculty since 1988. O'Donoghue is also a graduate
of Fort Lewis College, with a master's degree and Ph.D. from the New
Mexico Institute of Mining and Technology.
