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…
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…
The rapidly oscillating Ap star gamma Equ: linear polarization as an enhanced pulsation diagnostic?
S. Hubrig, S. P. Jarvinen, I. Ilyin +2
We present the first short time scale observations of the roAp star gamma Equ in linear polarized light obtained with the PEPSI polarimeter installed at the LBT. These observations…
Giant white-light flares on fully convective stars occur at high latitudes
Ekaterina Ilin, Katja Poppenhaeger, Sarah J. Schmidt +7
White-light flares are magnetically driven localized brightenings on the surfaces of stars. Their temporal, spectral, and statistical properties present a treasury of physical info…
Magnetic field geometry and magnetospheric environment of the strongly magnetic Of?p star NGC 1624-2
S. P. Järvinen, S. Hubrig, M. Schöller +3
NGC 1624-2 is an O7f?p star with a reported probable polar magnetic field strength 20 kG, which is the strongest magnetic field ever measured in an O-type star. We study the…
