Author: Tiago CampanteNew insights on stellar evolution and stellar interiors physics are being made possible by asteroseismology. Throughout the course of the Kepler mission, asteroseismology has also played an important role in the characterization o ... more
Author: Meetu VermaActive region NOAA 12597 emerged on 22 September 2016 in southern hemisphere.
The region was observed two days later on 24 September 2016 with GREGOR, VTT,
NST, and Hinode during a campaign organized as part of the SOLARNET in ... more
Author: Rudolf KommWe study the solar-cycle variation of the zonal and meridional flow in the near-surface layers of the solar convection zone from the surface to a depth of about 16 Mm. We have analyzed Dopplergrams obtained with the Michelson Dop ... more
Author: Jörn WarneckeThe magnetic field in the Sun undergoes a cyclic modulation with a reversal typically every 11 years due to a dynamo operating under the surface. We simulate a solar-type star, where the interplay between convection and rotation ... more
Author: Daniel ReeseOne of the greatest challenges in interpreting the pulsations of rapidly rotating stars is mode identification, i.e. correctly matching theoretical modes to observed pulsation frequencies. Indeed, the latest observations as well ... more
Author: Vincent BöningIn this study, we present first inversion results for deep meridional flow using spherical Born approximation kernels and time-distance helioseismology.
The computation of Born approximation kernels for flows has only recently be ... more
