Asteroseismology has grown from its beginnings three decades ago to a mature field
teeming with discoveries and applications. This phenomenal growth has been enabled by …

Binary stars are crucial laboratories for stellar physics, so have been photometric targets for
space missions beginning with the very first orbiting telescope (OAO-2) launched in 1968 …

Hot subluminous stars of spectral type B and O are core helium-burning stars at the blue end
of the horizontal branch or have evolved even beyond that stage. Most hot subdwarf stars …

Aims. The complex physics of close binary stars is made even more challenging by the
proximity effects that affect it. Understanding the influence of these proximity effects is one of …

The precision of photometric and spectroscopic observations has been systematically
improved in the last decade, mostly thanks to space-borne photometric missions and ground …

We present a comprehensive analysis of planetary phase variations, including possible
planetary light offsets, using eighteen quarters of data from the Kepler space telescope. Our …

We have discovered a class of eccentric binary systems within the Kepler data archive that
have dynamic tidal distortions and tidally induced pulsations. Each has a uniquely shaped …

In light of substantial new discoveries of hot subdwarfs by ongoing spectroscopic surveys
and the availability of the Gaia mission Early Data Release 3 (EDR3), we compiled new …

Context. Very high quality light curves are now available for thousands of detached eclipsing
binary stars and transiting exoplanet systems as a result of surveys for transiting exoplanets …

Context. About a third of the hot subdwarfs of spectral type B (sdBs), which are mostly core-
helium-burning objects on the extreme horizontal branch, are found in close binaries with …
