Solar magnetism eXplorer (SolmeX)

H. Peter, L. Abbo, V. Andretta +36

The magnetic field plays a pivotal role in many fields of Astrophysics. This is especially true for the physics of the solar atmosphere. Measuring the magnetic field in the upper s…

EUV jets, type III radio bursts and sunspot waves investigated using SDO/AIA observations

D. E. Innes, R. H. Cameron, S. K. Solanki

Images from the Solar Dynamics Observatory (SDO) at 211A are used to identify the solar source of the type III radio bursts seen in WIND/WAVES dynamic spectra. We analyse a 2.5 hou…

Convective Nature of Sunspot Penumbral Filaments: Discovery of Downflows in the Deep Photosphere

Jayant Joshi, A. Pietarila, J. Hirzberger +3

We study the velocity structure of penumbral filaments in the deep photosphere to obtain direct evidence for the convective nature of sunspot penumbrae. A sunspot was observed at h…

Solar irradiance variability: A six-year comparison between SORCE observations and the SATIRE model

Will T. Ball, Yvonne C. Unruh, Natalie A. Krivova +2

Aims: We investigate how well modeled solar irradiances agree with measurements from the SORCE satellite, both for total solar irradiance and broken down into spectral regions on t…

Solar total irradiance in cycle 23

N. A. Krivova, S. K. Solanki, W. Schmutz

The apparently unusual behaviour of the TSI during the most recent minimum of solar activity has been interpreted as evidence against solar surface magnetism as the main driver of…
