Asteroseismic rotation rates of hot subdwarf B stars hint at transient accretion from leftover common envelope matter
Facundo D. Moyano, Hongwei Ge, Zhanwen Han +6
Asteroseismology enabled measuring the rotation rate in the deep stellar interiors of stars across several evolutionary phases, advancing the theory of angular momentum transport i…
BlackGEM observations of compact pulsating stars: Mode identification for the DOV PG 1159-035 using multi-colour photometry
P. Ranaivomanana, C. Johnston, M. Uzundag +10
While space-based telescopes offer unparalleled precision for asteroseismology, ground-based observations remain crucial for identifying compact pulsator candidates and enabling th…
Unsupervised learning for variability detection with Gaia DR3 photometry. The main sequence-white dwarf valley
P. Ranaivomanana, C. Johnston, G. Iorio +4
The unprecedented volume and quality of data from space- and ground-based telescopes present an opportunity for machine learning to identify new classes of variable stars and pecul…
Variability in hot sub-luminous stars and binaries: Machine-learning analysis of Gaia DR3 multi-epoch photometry
P. Ranaivomanana, M. Uzundag, C. Johnston +3
Hot sub-luminous stars represent a population of stripped and evolved red giants that is located on the extreme horizontal branch. Since they exhibit a wide range of variability du…
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…
