Waves and oscillations have been observed in the Sun's atmosphere for over half a century.
While such phenomena have readily been observed across the entire electromagnetic …

The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool
photosphere and the intensely heated transition region and corona. Compressible and …

A magnetic field modifies the properties of waves in a complex way. Significant advances
have been made recently in our understanding of the physics of sunspot waves with the help …

Oscillatory phenomena observed in sunspot umbrae and penumbrae are reviewed and
critically discussed. A natural interplay between the thermal atmospheric stratification and …

We use images of high spatial and temporal resolution, obtained using both ground-and
space-based instrumentation, to investigate the role magnetic field inclination angles play in …

We seek to clarify the nature of running penumbral (RP) waves: are they chromospheric
trans-sunspot waves or a visual pattern of upward-propagating waves? Full Stokes …

Exploiting high-resolution observations made by the Solar Optical Telescope on board
Hinode, we investigate the spatial distribution of the power spectral density of the oscillatory …

Sunspots are intense collections of magnetic fields that pierce through the Sun's
photosphere, with their signatures extending upwards into the outermost extremities of the …

We present simultaneous, high-resolution, multi-temperature observations of running waves
and umbral flashes in a sunspot with the Interface Region Imaging Spectrograph. We …

Context. An analysis of the oscillations above sunspots was carried out using simultaneous
ground-based and Solar Dynamics Observatory (SDO) observations (Si i 10827 Å, He i …
