Space Science Reviews, ISSN 0038-6308, 12/2016, Volume 204, Issue 1, pp. 49 - 82
Journal Article
Astronomy and Astrophysics, ISSN 0004-6361, 12/2018, Volume 620, p. A104
Context. In a recent statistical study of sunspots in 79 active regions, the vertical magnetic field component Bver averaged along the umbral boundary is found to be independent of sunspot size...
