Dimming and pulsation shock of the coalesced star V838 Monocerotis

T. Kamiński, C. E. Woodward, T. Liimets +3

V838 Mon is the remnant of a stellar merger that occurred in 2002. Twenty-four years after the merger, the remnant closely resembles a red supergiant, but its luminosity is sustain…

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…

Anti-Solar Differential Rotation May Have Revived Magnetic Braking in the Subgiant 31 Aquilae

Travis S. Metcalfe, Jennifer L. van Saders, Thomas R. Ayres +16

Recent observations have shown that sufficiently slow rotation disrupts the organization of large-scale magnetic field in older main-sequence stars, leading to weakened magnetic br…

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…
