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…
