Spectrum of the secondary component and new orbital elements of the massive triple star Delta Ori A
A. Oplištilová, P. Mayer, P. Harmanec +13
Orionis is the closest massive multiple stellar system and one of the brightest members of the Orion OB association. The primary (Aa1) is a unique evolved O star. In this work,…
Analysis of eight magnetic chemically peculiar stars with rotational modulation
O. Kobzar, V. Khalack, D. Bohlender +9
Since the end of 2018, the Transiting Exoplanet Survey Satellite (TESS) has provided stellar photometry to the astronomical community. We have used TESS data to study rotational mo…
Using Computational Models to Uncover the Parameters of Three Kepler Binaries: KIC 5957123, KIC 8314879, and KIC 10727668
Padraic Odesse, Catherine Lovekin
Theories of stellar convective core overshoot can be examined through analysis of pulsating stars. Better accuracy can be achieved by obtaining external constraints such as those p…
The Effects of Metallicity on Convective Overshoot Behaviour in Models of delta Scuti Variable Stars
V. Dornan, C. C. Lovekin
delta Scuti variables are stars which exhibit periodic changes in their luminosity through radial and non-radial pulsations. Internally, these stars have relatively small convectiv…
Five years of BRITE-Constellation photometry of the luminous blue variable P Cygni: properties of the stochastic low-frequency variability
Ashley Elliott, Noel D. Richardson, Herbert Pablo +9
Luminous Blue Variables (LBVs) are massive stars that are likely to be a transitionary phase between O stars and hydrogen-free classical Wolf-Rayet stars. The variability of these…
Space Photometry with BRITE-Constellation
Weiss W. W, Zwintz K., Kuschnig R. +16
BRITE-Constellation is devoted to high-precision optical photometric monitoring of bright stars, distributed all over the Milky Way, in red and/or blue passbands. Photometry from s…
TESS Cycle 1 observations of roAp stars with 2-min cadence data
D. L. Holdsworth, M. S. Cunha, D. W. Kurtz +41
We present the results of a systematic search for new rapidly oscillating Ap (roAp) stars using the 2-min cadence data collected by the Transiting Exoplanet Survey Satellite (TESS)…
Transport of angular momentum by stochastically excited waves as an explanation for the outburst of the rapidly rotating Be star HD49330
C. Neiner, U. Lee, S. Mathis +3
HD49330 is a Be star that underwent an outburst during its five-month observation with the CoRoT satellite. An analysis of its light curve revealed several independent p and g puls…
Rotational and pulsational variability in the TESS light curve of HD27463
V. Khalack, C. Lovekin, D. M. Bowman +8
The new photometric data on pulsating Ap star HD~27463 obtained recently with the Transiting Exoplanet Survey Satellite (\textit{TESS}) are analysed to search for variability. Our…
The first view of Scuti and Doradus stars with the TESS mission
V. Antoci, M. S. Cunha, D. M. Bowman +63
We present the first asteroseismic results for Scuti and Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilise the 2-min cadence TESS data for a sample…
Magnetic OB[A] Stars with TESS: probing their Evolutionary and Rotational properties (MOBSTER) - I. First-light observations of known magnetic B and A stars
A. David-Uraz, C. Neiner, J. Sikora +21
In this paper we introduce the MOBSTER collaboration and lay out its scientific goals. We present first results based on the analysis of nineteen previously known magnetic O, B and…
Diverse Variability of O and B Stars Revealed from 2-minute Cadence Light Curves in Sectors 1 and 2 of the TESS Mission: Selection of an Asteroseismic Sample
May G. Pedersen, Sowgata Chowdhury, Cole Johnston +18
Uncertainties in stellar structure and evolution theory are largest for stars undergoing core convection on the main sequence. A powerful way to calibrate the free parameters used…
Convection and Overshoot in models of gamma Doradus and delta Scuti stars
C. C. Lovekin, J. A. Guzik
We investigate the pulsation properties of stellar models representative of Scuti and Doradus variables. We have calculated a grid of stellar models from 1.2 to 2.2 M$_{\od…
2-D and 3-D Models of Convective Turbulence and Oscillations in Intermediate-Mass Main-Sequence Stars
Joyce A. Guzik, T. H. Morgan, N. J. Nelson +5
We present multidimensional modeling of convection and oscillations in main-sequence stars somewhat more massive than the Sun, using three separate approaches: 1) Using the 3-D pla…
Behaviour of Pulsations in Hydrodynamic Models of Massive Stars
C. C. Lovekin, J. A. Guzik
We have calculated the pulsations of massive stars using a nonlinear hydrodynamic code including time-dependent convection. The basic structure models are based on a standard grid…
Pulsations as a Driver for LBV Variability
C. Lovekin, J. Guzik
Among the most spectacular variable stars are the Luminous Blue Variables (LBVs), which can show three types of variability. The LBV phase of evolution is poorly understood, and th…
