The rich oscillation spectra determined for the two stars, ν Eridani and 12 Lacertae, present an interesting challenge to stellar modelling. The stars are hybrid objects showing not only a number of modes at frequencies typical for β Cep stars but also one mode at frequency typical for SPB stars. We construct seismic models of these stars considering uncertainties in opacity and element distribution. We also present estimate of the interior rotation rate and address the matter of mode… 

Figures and Tables from this paper


Recent progress in the seismic interpretation of field β Cep stars has resulted in improvements of the physical description in the stellar structure and evolution model computations of massive stars.


A method for the asteroseismic analysis of β Cephei stars is presented and applied to the star ν Eridani. The method is based on the analysis of rotational splittings and their asymmetries using

The β Cep/SPB star 12 Lacertae: extended mode identification and complex seismic modelling

Results of mode identification and seismic modelling of the β Cep/SBP star 12 Lacertae are presented. Using data on the multi-colour photometry and radial velocity variations, we determine or

Testing the effects of opacity and the chemical mixture on the excitation of pulsations in B stars

The B-type pulsators known asβ Cephei and Slowly Pulsating B (SPB) stars present pulsations driven by theκ mechanism, which operates thanks to an opacity bump due to the iron group elements. In

New Beta Cephei Stars from the KELT Project

We present the results of a search for Galactic β Cephei stars, which are massive pulsating stars with both pressure modes and mixed modes. Thus, these stars can serve as benchmarks for seismological

Constraints on opacities from complex asteroseismology of B-type pulsators: the β Cephei star θ Ophiuchi

We present results of a comprehensive asteroseismic modelling of the β Cephei variable θ Ophiuchi. We call these studies complex asteroseismology because our goal is to reproduce both pulsational

Opacity Effects on Pulsations of Main-Sequence A-Type Stars

Opacity enhancements for stellar interior conditions have been explored to explain observed pulsation frequencies and to extend the pulsation instability region for B-type main-sequence variable

Interpretation of the BRITE oscillation data of the hybrid pulsator ν Eridani: a call for the modification of stellar opacities

The analysis of the BRITE oscillation spectrum of the main sequence early B-type star $\nu$ Eridani is presented. Only models with the modified mean opacity profile can account for the observed

An asteroseismic study of the O9V star HD 46202 from CoRoT space-based photometry

The O9V star HD46202, which is a member of the young open cluster NGC 2244, was observed by the CoRoT satellite in October/November 2008 during a short run of 34 days. From the very high-precision

Seismic modelling of early B-type pulsators observed by BRITE – I. θ Ophiuchi

We analyse time-series observations from the BRITE-Constellation of the well known $\beta$ Cephei type star $\theta$ Ophiuchi. Seven previously known frequencies were confirmed and nineteen new



Asteroseismology of the β Cephei star ν Eridani: massive exploration of standard and non-standard stellar models to fit the oscillation data

We present the results of a detailed seismic modelling of the Cephei star Eridani with the Li‘ ege evolution and pulsation codes. We selected four clearly detected, well-identified and independent

Asteroseismology of the β Cephei star ν Eridani: interpretation and applications of the oscillation spectrum

The oscillation spectrum of v Eri is the richest known for any variable of the β Cephei type. We interpret the spectrum in terms of normal mode excitation and construct seismic models of the star.
