Isochrone-cloud fitting and asteroseismology of the Kepler open cluster NGC6866
Haotian Wang, Gang Li, Dario J. Fritzewski +2
We investigate how isochrones computed with different input physics and initial conditions affect the age dating of the open cluster NGC 6866, and compare the results with asterose…
Evolution of the near-core rotation frequency of 2,497 intermediate-mass stars from their dominant gravito-inertial mode
Conny Aerts, Timothy Van Reeth, Joey S. G. Mombarg +1
We combined Gaia DR3 and TESS photometric light curves to estimate the internal physical properties of 2,497 gravity-mode pulsators. We relied on asteroseismic properties of Kepler…
MOCKA -- A PLATO mock asteroseismic catalogue: Simulations for gravity-mode oscillators
N. Jannsen, A. Tkachenko, P. Royer +14
With ESA's PLATO space mission set for launch in December 2026, a new photometric legacy and a future of new scientific discoveries await. In this work we investigate PLATO's poten…
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…
Photometric detection of internal gravity waves in upper main-sequence stars. IV. Comparable stochastic low-frequency variability in SMC, LMC, and Galactic massive stars
Dominic M. Bowman, Pieterjan Van Daele, Mathias Michielsen +1
Massive main-sequence stars have convective cores and radiative envelopes, but also sub-surface convection zones caused by partial ionisation. However, the convective properties de…
Estimates of (convective core) masses, radii, and relative ages for 14,000 Gaia-discovered gravity-mode pulsators monitored by TESS
Joey S. G. Mombarg, Conny Aerts, Timothy Van Reeth +1
Gravito-inertial asteroseismology saw its birth from the 4-years long light curves of rotating main-sequence stars assembled by the Kepler space telescope. High-precision measureme…
