Polarimetric asteroseismology of beta Crucis
Here we report the detection of polarization variations due to nonradial modes in the {beta} Cephei star {beta} Crucis. In so doing we confirm 40- year-old predictions of... -
B stars UBV and SpType catalogue
The present work represents a catalogue of spectral classification and photometric data of 2047 B type stars using the {Delta}Q method. Cone search capability for table... -
Search for variable subdwarf B stars in TESS I
We report the results of our search for pulsating subdwarf B stars in full frame images, sampled at 30 min cadence and collected during Year 1 of the TESS mission. Year 1 covers... -
Longitudinal magnetic field of 6 B stars
Rapidly rotating early-type stars with strong magnetic fields frequently show H{alpha} emission originating in centrifugal magnetospheres (CMs), circumstellar structures in... -
Mode identification in 3 pulsating hot subdwarfs
We report on the detection of pulsations of three pulsating subdwarf B stars observed by the Transiting Exoplanet Survey Satellite (TESS) satellite and our results of mode... -
Luminosities of 34 slowly pulsating B stars
We provide three statistical model prescriptions for the bolometric corrections appropriate for B-type stars as a function of (i) T_eff_, (ii) T_eff_ and logg, and (iii) T_eff_,... -
TESS A and B stars and the Maia variables
Classification of over 50000 TESS stars in sectors 1-18 has resulted in the detection of 766 pulsating main-sequence B stars as well as over 5000 {delta} Scuti, 2300 {gamma}... -
Rotational modulation in TESS B stars
Light curves and periodograms of 160 B stars observed by the Transiting Exoplanet Survey Satellite (TESS) space mission and 29 main-sequence B stars from Kepler and K2 were used... -
p-mode-dominated subdwarf B pulsators in binaries
This paper presents spectroscopic and seismic analyses of two rare hybrid pulsating subdwarf B (sdB) stars, PG 0048+091 and PG 1315-123, which are dominated by pressure (p)-mode... -
Nitrogen abundances for Be and B stars
Photospheric nitrogen abundances for a sample of 26 Be stars and 16 normal B stars were found using high-resolution spectra from the Magnetism in Massive Stars (MiMeS)... -
MiMeS survey of magnetism in massive stars
The MiMeS (Magnetism in Massive Stars) project is a large-scale, high-resolution, sensitive spectropolarimetric investigation of the magnetic properties of O- and early B-type... -
Bayesian statistics for massive stars
Spectral analysis is a powerful tool to investigate stellar properties and it has been widely used for decades now. However, the methods considered to perform this kind of... -
KIC 10670103 frequency spectrum
We analyse 2.75yr of Kepler spacecraft observations of the pulsating subdwarf B star KIC 10670103. These 1.4 million measurements have an impressive duty cycle of 93.8 per cent,... -
EC 01541-1409 pulsations frequencies
We present follow-up observations of the pulsating subdwarf B (sdB) star EC 01541-1409 as part of our efforts to resolve pulsation spectra for use in asteroseismological... -
Variables in Cygnus OB2
We present the results of the photometric CCD search for B-type variables in the central region of the Cygnus OB2 association. We discover 29 new variables including two Beta... -
Slowly pulsating B stars from TESS, LAMOST & Gaia DR3
This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have... -
OB-type pulsating stars with TESS, LAMOST & Gaia
O- and B-type (OB-type) pulsating stars are important objects for studying the structure and evolution of massive stars through asteroseismology. A large amount of data from... -
Far-UV spectroscopic atlas of B stars
We have constructed a detailed spectral atlas covering the wavelength region 930-1225{AA} for 10 sharp-lined B0-B9 stars near the main sequence. Most of the spectra we assembled... -
Rotation signature of TESS B-type stars
Stellar rotation is a fundamental observable that drives different aspects of stellar and planetary evolution. In this work, we present an unprecedented manifold analysis of 160... -
RSGs in the LMC & sp. follow-up for LMC & SMC
The binary fraction of unevolved massive stars is thought to be 70%-100% but there are few observational constraints on the binary fraction of the evolved version of a subset of...
