Scaling relations
How reliable are the asteroseismic scaling relations for deriving stellar mass and radius? Novel constraints using features natually formed in stellar populations.
Near-surface effect
A homogenous and self-consistent approach to correct surface-induced frequency offset in stellar models.
Very low-mass and underluminous stars
The discovery of stars that should not exist, unless they have undergone binary interactions
Mode (de-)coupling
A new techinque (stretched frequency) recovers pure p mode oscillations in red giants.
Giant oscillations
Extractions of stellar oscillation parameters for >5000 subgiants and red giants.
K-dwarf oscillations
Filling the gap of space photometry: asteroseismology of K dwarfs with Keck/KPF and VLT/ESPRESSO.
Activity-age relations
Calibrations using stellar kinematics as field-star isochrones
