First Announcement of the IAU Symposium 354 “Solar and Stellar Magnetic Fields: Origins and Manifestations”, that will be held from June 30 to July 6, 2019 in the city of Copiapó, Chile.
We cordially invite you to participate in the conference and at the same time kindly ask you to share this information with your colleagues and students.
The main goal of the Symposium is to bring together solar and stellar astronomers to discuss common problems related to the origin of solar and stellar magnetic fields, their atmospheric/coronal effects, their impact on planetary atmospheres, and their role on stellar formation and evolution. Solar magnetic fields and their effects have been studied with high resolution and motivated detailed theoretical modeling. Traditionally, the results and concepts of solar research are applied to other stars. However, observations of stellar magnetic fields and activity have substantially expanded the framework of solar studies, and created new challenges that need to be addressed. For example, the discovery of superflares on solar-type stars raised questions about the structure and dynamics of magnetic fields that can be substantially different from the case of solar flares. Investigations of stellar cycles have shown that the solar dynamo may be in a transition region between periods of high and low activity. Investigation of relationships between solar and stellar magnetism has become critically important for both fields. Therefore, it is very timely to overview the current state of solar and stellar magnetism studies, exchange recent results and ideas, and discuss needs and plans for further investigations.
The IAU Symposium will provide an ideal venue for such interdisciplinary discussion. The Symposium will bring together experts from various fields of solar physics and astrophysics, including observers, theorists and modelers, to discuss recent advances, exchange ideas, make future plans, and develop new collaborations.
The Symposium will include an open public session on solar eclipses and planetary transits. The goal of this session is to discuss how the eclipses and transits provide new information about solar and stellar magnetic fields. In addition, this session will present a broad historical overview of solar eclipses, planetary transits, their role in astronomy, as well as a general talk on habitability of exoplanets.
The city of Copiapó is close to but outside the path of the total solar eclipse. A bus tour to watch the total eclipse near the totality strip (July 2nd) will be organized.
