Magnetic activity in cool stars: manifestations and relevance to exoplanets
E. Işık, 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

Magnetic activity on the young Sun: a case study of EK Draconis
A. Görgei, L. Kriskovics, K. Vida +8
Context. Young, solar analogue stars provide key insights into the early stages of stellar evolution, particularly in terms of magnetic activity and rotation. Their rapid rotation,…
The incidence of magnetism in blue and yellow straggler stars
S. Hubrig, S. P. Järvinen, I. Ilyin +1
Our understanding of the generation of magnetic fields in intermediate-mass and massive OBA stars remains limited. Some theories have proposed that their magnetic fields could be a…
A magnetic tertiary in the most massive compact triple-star system
S. Hubrig, A. Vigna-Gómez, S. P. Järvinen +2
The system TIC 470710327 is comprised of three main-sequence OB stars, with an inner compact 1.10 d eclipsing binary and a non-eclipsing tertiary on a 52.04 d orbit. With the terti…
A search for Maunder-minimum candidate stars
S. P. Järvinen, K. G. Strassmeier
Stars with very low levels of magnetic activity provide an opportunity for a more quantitative comparison with the Sun during its Maunder minimum. We employ spectra from the RAVE s…
The enigmatic magnetic field of the planet hosting Herbig Ae/Be star HD169142
S. Hubrig, S. P. Jarvinen, I. Ilyin +1
Recent observations of the accretion disk around the Herbig Ae/Be star HD169142 revealed its complex and asymmetric morphology indicating the presence of planets. The knowledge of…
First snapshot of a magnetosphere around a Herbig Ae/Be star
S. P. Järvinen, S. Hubrig, M. Küker +6
The Herbig Ae/Be star HD190073 is one of the very few magnetic Herbig Ae/Be stars for which close low-mass companions have been reported. Previously published magnetic field measur…
Detection of extragalactic magnetic massive stars
S. Hubrig, M. Schöller, S. P. Jarvinen +4
Studies of the magnetic characteristics of massive stars have recently received significant attention because they are progenitors of highly magnetised compact objects. Stars initi…
Extreme Magnetic Field Modulus Variability of the Bp star HD 57372
S. Hubrig, S. D. Chojnowski, S. P. Jarvinen +2
Context. In chemically peculiar Ap/Bp stars with large-scale organised magnetic fields with a simple centred dipole configuration, the ratio between the maximum and the minimum of…
Characterizing the dynamical magnetosphere of the extremely slowly rotating magnetic O9.7 V star HD 54879 using rotational modulation of the H profile
Manfred Küker, Silva Järvinen, Swetlana Hubrig +2
The magnetic field in the O9.7 V star HD54879 has been monitored for almost a decade. Spectropolarimetric observations reveal a rather strong mean longitudinal magnetic field that…
Are magnetic fields universal in O-type multiple systems?
S. Hubrig, S. P. Jarvinen, I. Ilyin +2
Although significant progress has been achieved in recent surveys of the magnetism in massive stars, the origin of the detected magnetic fields remains to be the least understood t…
