Dynamos, the drivers of solar and stellar activity
Following Cowling's anti-dynamo theorem of 1933, there was a long period during which the very existence of dynamos was unclear. Even with the emergence of...

PublicationExtracting rotation rates on 27-d TESS-like light curves downgrading Kepler data
Evolution of surface magnetic features in the star, such as stellar spots or faculae, can leave a signature in the lightcurves. These features allow us to study...

TalkFinding extra-solar planets in the presence of stellar jitter
The RV method is responsible for discovering the majority of planets that orbit stars other than our Sun. However, one problem with this technique is that...

PublicationGiant white-light flares on fully convective stars occur at high latitudes
In a systematic analysis of fully convective stars observed with TESS, we detected four stars that displayed giant flares that were...

TalkIAU G5 -- The GALAH survey: science goals and highlights to date
The field of Galactic archaeology has been very active in recent years, with a major influx of data from the Gaia satellite and large spectroscopic surveys. The...

TalkIAU G5 Talk: Winds of Magnetic Massive Stars
Massive stars (at least eight times as massive as the Sun) possess strong stellar winds driven by radiation. With the advent of the so called MiMeS...

TalkIAU G5: "Extreme Precision Stellar Spectroscopy"
The new generation of spectrometers designed for extreme precision radial velocities enable correspondingly precise stellar spectroscopy. It is now fruitful to...

PublicationInvestigating magnetic activity of F stars with the Kepler mission
The dynamo process is believed to drive the magnetic activity of stars like the Sun that have an outer convection zone. Large spectroscopic surveys showed that...
