Magnetic activity in cool stars: manifestations and relevance to exoplanets
E. IÅık, A. Valio, A. Strugarek +10
Understanding stellar magnetic activity is central to exoplanet science in two ways: it sets the dynamic astrospheric boundary condition governing planetary space environments, and…
Star Planet Interactions
Arghyadeep Paul, Kristina Kislyakova, Manuel Güdel +13
Star-planet interactions (SPIs) describe the continuous exchange of energy, momentum, and mass between exoplanets and their host stars through radiative, tidal, magnetic, and parti…
Star-Planet Interactions: The Instrumentation Perspective
H. Korhonen, P. Figueira, B. Montet +4
Star-Planet Interactions (SPIs) produce observable phenomena across the electromagnetic spectrum, from X-ray and ultraviolet emission tracing magnetic activity and atmospheric esca…
Detection of a large-scale organized 2 kG order magnetic field in the Herbig Ae star HD179218
S. P. Järvinen, S. Hubrig, M. Schöller +5
While about two dozen Herbig Ae/Be stars have been reported to be magnetic, only two of them, HD101412 and HD190073, have had their magnetic field geometries studied in the past. T…
The magnetic fields in Be stars are stronger than previously suggested
S. Hubrig, S. P. Järvinen, M. Schöller +1
Recent observational studies suggest that Be stars most likely are formed through the process of mass transfer in binary systems. In view of the wide consensus that the origin of t…
Magnetic field detections in massive systems at different stages of interaction
S. Hubrig, M. Abdul-Masih, S. P. Jarvinen +4
Despite the importance of magnetic fields in massive stars, their origin is widely debated and still not well understood. With the mounting evidence for the importance of studying…
