We used extensive ground-based multisite and archival spectroscopy to derive observational constraints for a seismic modelling of the magnetic β Cep star V2052 Ophiuchi. The line-profile variability is dominated by a radial mode (f1 = 7.148 46 d−1) and by rotational modulation (Prot = 3.638 833 d). Two non-radial low-amplitude modes (f2 = 7.756 03 d−1 and f3 = 6.823 08 d−1) are also detected. The four periodicities that we found are the same as the ones discovered from a companion multisite…

This paper aims to precisely determine the masses and detect pulsation modes in the two massive components of Beta Cen with BRITE-Constellation photometry. In addition, seismic models for the
Forward seismic modeling of the pulsating magnetic B-type star HD 43317
The large-scale magnetic fields detected at the surface of about 10% of hot stars extend into the stellar interior, where they may alter the structure. Deep inner regions of stars are only observable
MOBSTER – V. Discovery of a magnetic companion star to the magnetic β Cep pulsator HD 156424
HD 156424 (B2 V) is a little-studied magnetic hot star in the Sco OB4 association, previously noted to display both high-frequency radial velocity (RV) variability and magnetospheric H α emission.
Discovery of a magnetic field in the CoRoT hybrid B-type pulsator HD 43317
Context. A promising way of testing the impact of a magnetic field on internal mixing (core overshooting, internal rotation) in mainsequence B-type stars is to perform asteroseismic studies of a

Magnetic characterization of the SPB/$\mathbf{\beta}$ Cep hybrid pulsator HD 43317
Large-scale magnetic fields at the surface of massive stars do not only influence the outer-most layers of the star, but also have consequences for the deep interior, only observationally accessible
On the first δ Sct–roAp hybrid pulsator and the stability of p and g modes in chemically peculiar A/F stars
Abstract Strong magnetic fields in chemically peculiar A-type (Ap) stars typically suppress low-overtone pressure modes (p modes) but allow high-overtone p modes to be driven. KIC 11296437 is the
Magnetic characterization and variability study of the magnetic SPB star o Lupi
Thanks to large dedicated surveys, large-scale magnetic fields have been detected for about 10% of early-type stars. We aim to precisely characterize the large-scale magnetic field of the magnetic
