PublicationPeriod, epoch, and prediction errors of ephemerides from continuous sets of timing measurements
Space missions such as Kepler and CoRoT have led to large numbers of eclipse or transit measurements in nearly continuous time series. This paper shows how to...

PublicationPeriodic mass-loss episodes due to an oscillation mode with variable amplitude in the hot supergiant HD 50064
Aims: We aim to interpret the photometric and spectroscopic variability of the luminous blue variable supergiant HD 50064 (V = 8.21). Methods: CoRoT space...

PublicationPersistent magnetic vortex flow at a supergranular vertex
Context. Photospheric vortex flows are thought to play a key role in the evolution of magnetic fields. Recent studies show that these swirling motions are...

PublicationPG 1618+563B: A new bright pulsating sdB star
The results of two runs of time-series photometry made at the Nordic Optical Telescope clearly show that the sdB star PG 1618+563B is a new member of the EC...

PublicationPG 1657+416: a new fast pulsating sdB star. Photometric observations and theoretical model comparison
Context: Since the discovery in 1997 of stellar oscillations in some B-type hot subdwarfs (sdBs), much effort is being made both observationally and...

PublicationPhase diversity restoration of sunspot images. I. Relations between penumbral and photospheric features
We investigate the dynamics of and the relations between small-scale penumbral and photospheric features near the outer penumbral boundary: penumbral grains...
