Time-distance helioseismology: A new averaging scheme for measuring flow vorticity
Jan Langfellner, Laurent Gizon, Aaron C. Birch
Time-distance helioseismology provides information about vector flows in the near-surface layers of the Sun by measuring wave travel times between points on the solar surface. Spec…

Amplitude variation and multiplet structures: Is PG1605+072 a slow rotator?
Jan Langfellner, Sonja Schuh, the MSST +1
The subdwarf B star PG1605+072, with an unusually low log g ~ 5.3, shows a high number of non-radial pulsation modes, making it a promising candidate for asteroseismology. This cou…
