Lennart Lindegren & Jackie Faherty Awarded Prizes for Dynamical Astronomy
The American Astronomical Society (AAS) Division on Dynamical Astronomy (DDA) is pleased to announce the recipients of its 2020 Dirk Brouwer Career Award and 2020 Vera Rubin Early Career Prize.
2020 Dirk Brouwer Career Award to Lennart Lindegren
The Dirk Brouwer Career Award (https://dda.aas.org/awards/br
Professor Lindegren has made a profound impact on the fields of astrometry and celestial mechanics. In a career spent working as part of large collaborations, his personal contributions have been significant and far-reaching, not only pioneering new observational techniques but also solving extraordinarily complicated data-reduction and analysis challenges. He established the innovative methodology by which a map of the sky can be synthesized from telemetry from a scanning satellite, and he was central to the production of the Hipparcos, Gaia DR1, and Gaia DR2 catalogs, which have provided unprecedented sources of discovery and new understanding.
Having obtained his PhD at Lund University in 1980, Professor Lindegren went on to spend most of his professional life at Lund, where he was a much-appreciated member of the teaching staff and famous for explaining complex problems. He served as Director of Lund Observatory for six years and mentored numerous PhD students, many of whom have gone on to successful careers of their own.
Last, but by no means least, Professor Lindegren has devoted his career to the success of the Hipparcos and Gaia missions. The breadth and depth of his contributions are evidenced in the hundreds of technical notes written for the development, definition and optimization of these missions; his work is meticulous, rigorous, clear, and insightful. Most notably, he played a key role in ensuring the success of Hipparcos after it was left in an unsuitable orbit, and he has been a driving force behind Gaia from its inception to the present day. His work has changed our understanding of the universe at a fundamental level.
The Brouwer Award is given to Professor Lindegren to recognize and celebrate his outstanding contributions to the field of dynamical astronomy. The enduring legacy of his work is such that future generations of astronomers may owe their success, and even careers, to his remarkable contributions.
2020 Vera Rubin Early Career Prize to Jacqueline Faherty
The Vera Rubin Early Career Prize (https://dda.aas.org/awards/ru
The award is made in recognition of Dr. Faherty’s work on the kinematics of very faint stars in the Milky Way as well as her leadership in developing unique ways to engage the public and professional science teams with the astronomical field fundamental to the study of dynamics: astrometry, the precise measurement of celestial objects’ positions and motions on the sky.
Dr. Faherty earned her PhD from Stony Brook University in 2011 under the direction of Adam Burgasser, Michael Shara, and Frederick Walter. There she initiated the Brown Dwarf Kinematics Project, which measured and compiled the 6D positions and velocities of all known brown dwarfs within 20 parsecs (about 65 light-years) of the Sun — a legacy data set for the astronomical community. She has used astrometric measurements to study a wide range of phenomena related to the kinematics and dynamics of young brown dwarfs and exoplanets.
Dr. Faherty has also advanced and supported dynamical astronomy by engaging scientists, students, and the general public at the American Museum of Natural History with dramatic visualizations of results from the Gaia space observatory. She has contributed to forming numerous essential collaborations, including the influential “BDNYC” research group and Backyard Worlds, a citizen-science project that engages members of the public to help discover previously missed brown dwarfs near the Sun.
Both Professor Lindegren and Dr. Faherty will be invited to give lectures at the 52nd annual meeting of the AAS Division on Dynamical Astronomy, to be held virtually 17-21 May 2021.

The object of the American Astronomical Society Division on Dynamical Astronomy (DDA, https://dda.aas.org), established in 1969, is the advancement of all aspects of dynamical astronomy — including celestial mechanics, solar system dynamics, stellar dynamics, the dynamics of the interstellar medium, and galactic dynamics — and the coordination of such research with other branches of science.
The American Astronomical Society (AAS, https://aas.org), established in 1899, is the major organization of professional astronomers in North America. Its membership (approx. 8,000) also includes physicists, mathematicians, geologists, engineers, and others whose research interests lie within the broad spectrum of subjects now comprising the astronomical sciences. The mission of the AAS is to enhance and share humanity’s scientific understanding of the universe, which it achieves through publishing, meeting organization, policy advocacy, education and outreach, and training and professional development.
