On the origin of sinusoidal brightness variations in F to O-type stars through radial velocities
E. Šipková, M. Skarka, M. Vaňko +3
Stellar variability may originate from various phenomena such as binarity, pulsations, or rotation. These mechanisms can induce flux variations of similar magnitudes, shapes, and p…

Magnetic field generation in mergers of massive main-sequence stars
Sebastian T. Ohlmann, Fabian R. N. Schneider, Friedrich K. Roepke +3
Magnetic fields are found in many astrophysical objects, ranging from galaxy clusters to the interstellar medium of galaxies and neutron stars. Strong surface magnetic fields are a…

B Shridharan, P Manoj, Vinod Chandra Pathak +10
We present a comprehensive study of mid-infrared neutral hydrogen (H~\textsc{i}) emission lines in 79 nearby (d 200 ) young stars using JWST/MIRI. We aim to identify mid-in…
Circini: A massive hierarchical triple system with an eclipsing binary
J. Švrčková, P. Harmanec, R. Klement +6
Circini is known to be a massive multiple system containing a 3.9 d inner eclipsing binary in a slightly elliptical orbit exhibiting slow apsidal motion and a distant tertiary…
Resonance locking and tidal evolution in rotating γ-Doradus binaries
L. Fellay, M. -A. Dupret, P. A. Kołaczek-Szymański
In binary systems, studying tidal interactions is key to understanding the evolution of binary populations. The primary dissipation process occurring in stars with radiative envelo…
Radio Burst from a Stellar Coronal Mass Ejection
J. R. Callingham, C. Tasse, R. Keers +15
Coronal mass ejections (CMEs) are massive expulsions of magnetised plasma from a star, and are the largest contributors to space weather in the Solar System. CMEs are theorized to…
The complex inner disk of the Herbig Ae star HD 100453 with VLTI/MATISSE
L. N. A. van Haastere, J. Varga, M. R. Hogerheijde +35
The inner regions of planet-forming disks hold invaluable insights for our understanding of planet formation. The disk around the Herbig star HD 100453 presents one such environmen…
Rethinking mass transfer: a unified semianalytical framework for circular and eccentric binaries. II. Orbital evolution due to nonconservative mass transfer
A. Parkosidis, S. Toonen, E. Laplace +1
Although mass transfer (MT) has been studied primarily in circular binaries, observations show that it also occurs in eccentric systems. We investigate orbital evolution during non…
Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features
