Detection of anomalous element distribution in the extremely slowly rotating magnetic O9.7 V star HD 54879
S. P. Järvinen, S. Hubrig., M. Schöller +4
The O9.7 V star HD 54879 is currently the only massive magnetic star whose magnetic field geometry and rotation period are not constrained. Over the last three years, we gathered a…
An absolute calibration of the near-infrared Period-Luminosity Relations of Type II Cepheids in the Milky Way and in the Large Magellanic Cloud
Piotr Wielgórski, Grzegorz Pietrzyński, Bogumił Pilecki +29
We present time-series photometry of 21 nearby Type II Cepheids in the near-infrared J, H and Ks passbands. We use this photometry, together with the Third Gaia Early Data Release…
Localizing flares to understand stellar magnetic fields and space weather in exo-systems
Ekaterina Ilin, Katja Poppenhäger, Julián D. Alvarado-Gómez
Stars are uniform spheres, but only to first order. The way in which stellar rotation and magnetism break this symmetry places important observational constraints on stellar magnet…
Could the Magnetic Star HD 135348 Possess a Rigidly Rotating Magnetosphere?
Rahul Jayaraman, Swetlana Hubrig, Daniel L. Holdsworth +4
We report the detection and characterization of a new magnetospheric star, HD 135348, based on photometric and spectropolarimetric observations. The TESS light curve of this star e…
A detailed understanding of the rotation-activity relationship using the 300 Myr old open cluster NGC 3532
D. J. Fritzewski, S. A. Barnes, D. J. James +2
The coeval stars of young open clusters provide insights into the formation of the rotation-activity relationship that elude studies of multi-age field populations. We measure the…
Rotation periods for cool stars in the open cluster NGC 3532. The transition from fast to slow rotation
D. J. Fritzewski, S. A. Barnes, D. J. James +1
A cluster intermediate in age between the Pleiades (150 Myr) and the Hyades (600 Myr) is needed to probe the rotational evolution, especially the transition between fast and slow r…
