The magnetic field of evolved hot stars
C. Neiner, A. Martin, G. Wade +1
About 10% of hot stars host a fossil magnetic field on the pre-main sequence and main sequence. However, the first magnetic evolved hot stars have been discovered only recently. An…
Magnetic characterization and variability study of the magnetic SPB star o Lup
B. Buysschaert, C. Neiner, A. J. Martin +5
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…
Detection of magnetic fields in chemically peculiar stars observed with the K2 space mission
B. Buysschaert, C. Neiner, A. J. Martin +4
We report the results of an observational study aimed at searching for magnetic pulsating hot stars suitable for magneto-asteroseismology. A sample of sixteen chemically peculiar s…
The evolution of magnetic fields from the main-sequence to very late stages
A. J. Martin
Magnetic fields have been detected in most if not all types of stars across the Hertzsprung-Russell diagram. Where present, these fields have the potential to significantly impact…
Discovery of an extremely weak magnetic field in the white dwarf LTT 16093 = WD2047+372
J. D. Landstreet, S. Bagnulo, A. Martin +1
Magnetic fields have been detected in several hundred white dwarfs, with strengths ranging from a few kG to several hundred MG. Only a few of the known fields have a mean magnetic…
Search for a Scalar Axion-like Particle at 34 GHz
P. L. Slocum, O. K. Baker, J. L. Hirshfield +8
Light axion-like particles (ALPs) that couple to two photons are allowed in a number of proposed extensions to the Standard Model of elementary particles. Of particular interest fr…
