The Arctowski Medal is presented every two years to recognize outstanding contributions to the study of solar physics and solar terrestrial relationships. The Medal is now presented with an award of $100,000, plus $100,000 to support research in solar physics and solar terrestrial relationships at an institution of the recipient's choice. The Arctowski Medal was established in 1958 by the bequest of Jane Arctowska in honor of her husband, Henryk Arctowski.
Mats Carlsson and Viggo Hansteen, will receive the 2017 Arctowski Medal. Working in collaboration, Carlsson and Hansteen led the development of the Bifrost numerical model of the solar atmosphere, a complex, three-dimensional “magnetohydrodynamics” model that has vastly improved our understanding of the physics of the sun, including its dynamic and constantly changing chromosphere, transition region, and corona.
Carlsson and Hansteen’s multifaceted approach, which combines both modeling and observations, allowed Bifrost to solve decades-old mysteries of the chromosphere, such as the physical mechanisms that drive chromospheric and coronal dynamics and energetics. It has also provided key insights into solar features such as the short-lived bursts of gases known as spicules, the micro solar flares known as Ellerman bombs, chromospheric surges, and coronal flares.
Among its many applications, the constantly evolving Bifrost code has played a central role in NASA’s Interface Region Imaging Spectrograph (IRIS) satellite project, which is exploring how the solar atmosphere is energized. Read more about their work
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.
