# Arctowski Medal

The Arctowski Medal is awarded by the U.S. National Academy of Sciences "for studies in solar physics and solar-terrestrial relationships." Named in honor of Henryk Arctowski, it was first awarded in 1969.

* Michelle F. Thomsen (2019) - For her fundamental contributions to our understanding of the relationships between the sun and its planetary bodies, with a particular emphasis on the physics of collisionless shocks and the dynamics of the planetary magnetospheres of Earth, Jupiter, and Saturn.
* Mats Carlsson and Viggo Hansteen (2017) - For their investigations in radiative transfer, magneto-hydro-dynamics, and plasma physics that has resulted in major advances in chromospheric diagnostics and our understanding of the physical mechanisms that drive chromospheric and coronal dynamics and energetics through the development and use of the Bifrost numerical model of the sun's atmosphere.
* Alexander J. Dessler (2015) - For his notable imagination in framing many of space science's most basic conceptions about the solar wind and interplanetary magnetic field and their interactions with the magnetospheres of Earth and other planets at the beginning of the Space Age.
* John T. Gosling (2013) - For elucidating fundamental issues in the physics of the solar atmosphere and solar wind, including revealing the "Solar Flare Myth", discovering bi-directional solar-electron streaming and, in the last decade, finding reconnection events in the solar wind.
* John W. Harvey (2011) - For major contributions to understanding the sun's magnetic fields and its interior structure, and for developing the instrumentation that has made these discoveries possible.
* Marcia Neugebauer (2010) - For definitively establishing the existence of the solar wind, critical to understanding the physics of the heliosphere, and for elucidating many of its key properties.
* Leonard F. Burlaga (2008) - For pioneering studies of the magnetized solar wind plasma from 0.3 to 102 AU, including the recent crossings of the Voyagers of the heliospheric termination shock and their entry in the heliosheath.
* Edward J. Smith (2005) - For his pioneering studies of the solar and heliospheric magnetic fields in deep space and planetary magnetic fields and their interaction with the solar wind.
* Roger K. Ulrich (2002) - For recognizing the solar five-minute oscillations as acoustic modes in the solar interior and systematically developing both the theory and the observations to establish today's precise standard model of the solar interior.
