Migration of Ca II H bright points in the internetwork
S. Jafarzadeh, R. H. Cameron, S. K. Solanki +4
The migration of magnetic bright point-like features (MBP) in the lower solar atmosphere reflects the dispersal of magnetic flux as well as the horizontal flows of the atmospheric…
Structure and Dynamics of Isolated Internetwork Ca II H Bright Points Observed by Sunrise
S. Jafarzadeh, S. K. Solanki, A. Feller +5
We aim to improve our picture of the low chromosphere in the quiet-Sun internetwork by investigating the intensity, horizontal velocity, size and lifetime variations of small brigh…
Signature of Differential Rotation in Sun-as-a-Star Ca II K Measurements
Luca Bertello, Alexei A. Pevtsov, A. Pietarila
The characterization of solar surface differential rotation (SDR) from disk-integrated chromospheric measurements has important implications for the study of differential rotation…
Comparison of Ground- and Space-based Longitudinal Magnetograms
A. Pietarila, L. Bertello, J. W. Harvey +1
We compare photospheric line-of-sight magnetograms from the Synoptic Long-term Investigations of the Sun (SOLIS) vector spectromagnetograph (VSM) instrument with observations from…
Instrumental and Observational Artifacts in Quiet Sun Magnetic Flux Cance llation Functions
A. Pietarila, J. Pietarila Graham
Under the assumption that the photospheric quiet-Sun magnetic field is turbulent, the cancellation function has previously been used to estimate the true, resolution-independent me…
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…
