Evolution of stellar magnetic activity: probing planet engulfment by red giants

Charlotte Gehan

The fraction of low-mass (LM) stars (M <= 1.5 Msun) showing photospheric activity in their light curve is larger on the horizontal branch (HB) than during the previous red giant br…

Enhanced magnetic activity in rapidly rotating binary stars

Jie Yu, Charlotte Gehan, Saskia Hekker +12

Stellar activity is fundamental to stellar evolution and the formation and habitability of exoplanets. The interaction between convective motions and rotation in cool stars results…

The PLATO Mission

Heike Rauer, Conny Aerts, Juan Cabrera +842

PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…

Mode Mixing and Rotational Splittings: II. Reconciling Different Approaches to Mode Coupling

J. M. Joel Ong, Charlotte Gehan

In the mixed-mode asteroseismology of subgiants and red giants, the coupling between the p- and g-mode cavities must be understood well in order to derive localised estimates of in…

A 20-Second Cadence View of Solar-Type Stars and Their Planets with TESS: Asteroseismology of Solar Analogs and a Re-characterization of pi Men c

Daniel Huber, Timothy R. White, Travis S. Metcalfe +50

We present an analysis of the first 20-second cadence light curves obtained by the TESS space telescope during its extended mission. We find a precision improvement of 20-second da…
