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…
First results from the LIFE project: discovery of two magnetic hot evolved stars
A. J. Martin, C. Neiner, M. E. Oksala +6
We present the initial results of the Large Impact of magnetic Fields on the Evolution of hot stars (LIFE) project. The focus of this project is the search for magnetic fields in e…
A spectroscopic study of the open cluster NGC 6250
A. J. Martin, M. J. Stift, L. Fossati +4
We present the chemical abundance analysis of 19 upper main-sequence stars of the young open cluster NGC 6250 (log t ~ 7.42 yr). This work is part of a project aimed at setting obs…
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…
A novel and sensitive method for measuring very weak magnetic fields of DA white dwarfs: A search for a magnetic field at the 250 G level in 40 Eri B
J. D. Landstreet, S. Bagnulo, G. G. Valyavin +4
Searches for magnetic fields in white dwarfs have clarified both the frequency of occurrence and the global structure of the fields found down to field strengths of the order of 50…
