Observational mapping of the mass discrepancy in eclipsing binaries. A new self-contained framework for concurrent analysis of photometric and spectroscopic time series
Nadya Serebriakova, Andrew Tkachenko, Cole Johnston +2
The mass discrepancy problem, observed in high-mass stars within eclipsing binaries, highlights systematic differences between dynamical and evolutionary mass estimates, challengin…

The ESO UVES/FEROS Large Programs of TESS OB pulsators. II. On the physical origin of macroturbulence
Nadya Serebriakova, Andrew Tkachenko, Conny Aerts
Spectral lines of hot massive stars are known to exhibit large excess broadening in addition to rotational broadening. This excess broadening is often attributed to macroturbulence…

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…
