The MODEST catalog of depth-dependent spatially coupled inversions of sunspots observed by Hinode/SOT-SP
J. S. Castellanos Durán, N. Milanovic, A. Korpi-Lagg +3
We present a catalog that we named MODEST containing depth-dependent information on the atmospheric conditions inside sunspot groups of all types. The catalog is currently composed…
Similarities of magnetoconvection in the umbra and in the penumbra of sunspots
B. Löptien, A. Lagg, M. van Noort +1
Context. It is unclear why there is a rather sharp boundary in sunspots between the umbra and the penumbra. Both regions exhibit magnetoconvection, manifesting in penumbral filamen…
Evolution of solar surface inflows around emerging active regions
N. Gottschling, H. Schunker, A. C. Birch +2
Solar active regions are associated with Evershed outflows in sunspot penumbrae, moat outflows surrounding sunspots, and extended inflows surrounding active regions. The latter hav…
No universal connection between the vertical magnetic field and the umbra-penumbra boundary in sunspots
B. Löptien, A. Lagg, M. van Noort +1
Context. It has been reported that the boundary between the umbra and the penumbra of sunspots occurs at a canonical value of the strength of the vertical magnetic field, independe…
A low upper limit on the subsurface rise speed of solar active regions
Aaron C. Birch, Hannah Schunker, Douglas C. Braun +4
Magnetic field emerges at the surface of the Sun as sunspots and active regions. This process generates a poloidal magnetic field from a rising toroidal flux tube, it is a crucial…
The shrinking Sun: a systematic error in local correlation tracking of solar granulation
B. Löptien, A. C. Birch, T. L. Duvall +2
Context. Local correlation tracking of granulation (LCT) is an important method for measuring horizontal flows in the photosphere. This method exhibits a systematic error that look…
