HD 60435: The star that stopped pulsating
Donald W. Kurtz, Gerald Handler, Daniel L. Holdsworth +10
HD 60435 is a well-known rapidly oscillating (roAp) Ap star with a series of alternating even and odd degree modes, making it a prime asteroseismic target. It is also an oblique pu…
Rotation and pulsation in Ap stars: first light results from TESS sectors 1 and 2
M. S. Cunha, V. Antoci, D. L. Holdsworth +36
We present the first results from the Transiting Exoplanet Survey Satellite (TESS) on the rotational and pulsational variability of magnetic chemically peculiar A-type stars. We an…
Triple system HD 201433 with a SPB star component seen by BRITE-Constellation: Pulsation, differential rotation, and angular momentum transfer
T. Kallinger, W. W. Weiss, P. G. Beck +17
Stellar rotation affects the transport of chemical elements and angular momentum and is therefore a key process during stellar evolution, which is still not fully understood. This…
The BRITE-Constellation Nanosatellite Space Mission And Its First Scientific Results
G. Handler, A. Pigulski, W. W. Weiss +15
The BRIght Target Explorer (BRITE) Constellation is the first nanosatellite mission applied to astrophysical research. Five satellites in low-Earth orbits perform precise optical t…
Massive pulsating stars observed by BRITE-Constellation. I. The triple system Beta Centauri (Agena)
A. Pigulski, H. Cugier, A. Popowicz +16
This paper aims to precisely determine the masses and detect pulsation modes in the two massive components of Beta Cen with BRITE-Constellation photometry. In addition, seismic mod…
Stellar modelling of Spica, a high-mass spectroscopic binary with a beta Cep variable primary component
A. Tkachenko, J. M. Matthews, C. Aerts +16
Binary stars provide a valuable test of stellar structure and evolution, because the masses of the individual stellar components can be derived with high accuracy and in a model-in…
