The surface magnetic field and chemical abundance distributions of the B2V helium-strong star HD184927
I. Yakunin, G. Wade, D. Bohlender +8
A new time series of high-resolution Stokes I and V spectra of the magnetic B2V star HD 184927 has been obtained in the context of the Magnetism in Massive Stars (MiMeS) Large Prog…
An In-Depth Spectroscopic Analysis of RR Lyr Variations over the Pulsation Cycle
L. Fossati, K. Kolenberg, D. V. Shulyak +5
The stellar parameters of RR Lyrae stars vary considerably over a pulsation cycle, and their determination is crucial for stellar modelling. We present a detailed spectroscopic ana…
The analysis of lithium in HD166473
A. V. Shavrina, V. Khalack, Y. Glagolevskij +4
The analysis of Li I 6708A line was performed for 6 rotational phases distributed over the whole rotational period (9.5 years) of HD166473. The magnetic field model was constructed…
Isospectrality for graph Laplacians under the change of coupling at graph vertices: necessary and sufficient conditions
Yulia Ershova, Irina I. Karpenko, Alexander V. Kiselev
Laplace operators on finite compact metric graphs are considered under the assumption that matching conditions at graph vertices are of and types. Assuming rational indepe…
The eccentric massive binary V380 Cyg: revised orbital elements and interpretation of the intrinsic variability of the primary component
A. Tkachenko, P. Degroote, C. Aerts +8
We present a detailed analysis and interpretation of the high-mass binary V380 Cyg, based on high-precision space photometry gathered with the Kepler space mission as well as high-…
Magnetic Doppler Imaging of He-strong star HD 184927
I. Yakunin, G. Wade, D. Bohlender +3
We have employed an extensive new timeseries of Stokes I and V spectra obtained with the ESPaDOnS spectropolarimeter at the 3.6-m Canada-France-Hawaii Telescope to investigate the…
