Populations of tidal and pulsating variables in eclipsing binaries
Alex Kemp, Jasmine Vrancken, Joey S. G. Mombarg +4
In this work, we seek to characterise a large sample of 14377 main sequence eclipsing binaries in terms of their stellar, asteroseismic, and orbital properties. We conduct manual v…
KIC 4150611: A quadruply eclipsing heptuple star system with a g-mode period-spacing pattern Asteroseismic modelling of the g-mode period-spacing pattern
Alex Kemp, Dario J Fritzewski, Timothy Van Reeth +7
In this work, we aim to estimate the stellar parameters of the primary (Aa) by performing asteroseismic analysis on its period-spacing pattern. We use the C-3PO neural network to p…
Statistical view of orbital circularisation with 14 000 characterised TESS eclipsing binaries
L. W. IJspeert, A. Tkachenko, C. Johnston +1
Eclipsing binaries are crucial for understanding stellar physics, allowing detailed studies of stellar masses, radii, and orbital dynamics. Recent space missions like the Transitin…
KIC 4150611: A quadruply eclipsing heptuple star system with a g-mode period-spacing pattern Eclipse modelling of the triple and spectroscopic analysis
Alex Kemp, Andrew Tkachenko, Guillermo Torres +8
KIC 4150611 is a high-order multiple composed of a triple system composed of the F1V primary (Aa), which is eclipsed on a 94.2d period by a tight 1.52d binary composed of two dim K…
The ESO UVES/FEROS Large Programs of TESS OB pulsators. I. Global stellar parameters from high-resolution spectroscopy
Nadya Serebriakova, Andrew Tkachenko, Sarah Gebruers +7
Modern stellar structure and evolution theory experiences a lack of observational calibrations for the interior physics of intermediate- and high-mass stars. This leads to discrepa…
Identifying and characterising the population of hot sub-luminous stars with multi-colour MeerLICHT data
P. Ranaivomanana, C. Johnston, P. J. Groot +9
Colour-magnitude diagrams reveal a population of blue (hot) sub-luminous objects with respect to the main sequence. These hot sub-luminous stars are the result of evolutionary proc…
Analysis of high-resolution FEROS spectroscopy for a sample of variable B-type stars assembled from TESS photometry
Sarah Gebruers, Andrew Tkachenko, Dominic M. Bowman +8
Spectroscopic data are necessary to break degeneracies in asteroseismic modelling of the interior structure in high- and intermediate-mass stars. We derive precise photospheric ste…
Detection of period-spacing patterns due to the gravity modes of rotating dwarfs in the TESS southern continuous viewing zone
S. Garcia, T. Van Reeth, J. De Ridder +3
Context: the theory of stellar evolution presents shortcomings when confronted with asteroseismic probes of interior physical properties. The differences between observations and t…
TESS Eclipsing Binary Stars. I. Short cadence observations of 4584 eclipsing binaries in Sectors 1-26
Andrej Prsa, Angela Kochoska, Kyle E. Conroy +44
In this paper we present a catalog of 4584 eclipsing binaries observed during the first two years (26 sectors) of the TESS survey. We discuss selection criteria for eclipsing binar…
An all-sky sample of intermediate- to high-mass OBA-type eclipsing binaries observed by TESS
Luc W. IJspeert, Andrew Tkachenko, Cole Johnston +4
Context. Intermediate- to high-mass stars are the least numerous types of stars and they are less well understood than their more numerous low-mass counterparts in terms of their i…
