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…
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…
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…
TESS detections of pulsations in Of?p stars in the Magellanic Clouds
S. Hubrig, R. Jayaraman, S. P. Järvinen
We used TESS observations to search for pulsations in six known Of?p stars in the Magellanic Clouds. We find evidence for pulsational variability in three Of?p stars: UCAC4 115-008…
Magnetic field of the roAp star KIC~10685175: observations versus theory
Fangfei Shi, Huawei Zhang, Swetlana Hubrig +5
KIC 10685175 is a roAp star whose polar magnetic field is predicted to be 6 kG through a non-adiabatic axisymmetric pulsation theoretical model. In this work, we aim to measure the…
Magnetic Fields
Markus Schöller, Swetlana Hubrig
In this chapter, we give a brief introduction into the use of the Zeeman effect in astronomy and the general detection of magnetic fields in stars, concentrating on the use of FORS…
