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…
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…
The impact of asteroseismically calibrated internal mixing on nucleosynthetic wind yields of massive stars
Hannah E. Brinkman, Lorenzo Roberti, Alex Kemp +3
Asteroseismology gives us the opportunity to look inside stars and determine their internal properties. Based on these observations, estimations can be made for the amount of the c…
