Convectively driven vortex flows in the Sun
J. A. Bonet, I. Marquez, J. Sanchez Almeida +2
We have discovered small whirlpools in the Sun, with a size similar to the terrestrial hurricanes (<~0.5 Mm). The theory of solar convection predicts them, but they had remained el…
Moat flow in the vicinity of sunspots for various penumbral configurations
S. Vargas Dominguez, L. Rouppe van der Voort, J. A. Bonet +3
High-resolution time series of sunspots have been obtained with the Swedish 1m Solar Telescope between 2003 and 2006 at different locations on the solar disc. Proper motions in sev…
Evidence of an association between the presence of penumbrae and strong radial outflows in sunspots
S. Vargas Domínguez, J. A. Bonet, V. Martinez Pillet +1
Time series of high-resolution images of the complex active region NOAA 10786 are studied. The observations were performed in G-band (430.5 nm) and in the nearby continuum (463.3 n…
The Evershed effect observed with 0.2 arsec angular resolution
J. Sanchez Almeida, I. Marquez, J. A. Bonet +1
We present an analysis of the Evershed effect observed with a resolution of 0.2 arcsec. Using the new Swedish 1-m Solar Telescope and its Littrow spectrograph, we scan a significan…
Simulation and analysis of VIM measurements: feedback on design parameters
D. Orozco Suarez, L. R. Bellot Rubio, S. Vargas Dominguez +3
The Visible-light Imager and Magnetograph (VIM) proposed for the ESA Solar Orbiter mission will observe a photospheric spectral line at high spatial resolution. Here we simulate an…
Phase diversity restoration of sunspot images I. Relations between penumbral and photospheric features
J. A. Bonet, I. Marquez, R. Muller +2
We investigate the dynamics of and the relations between small-scale penumbral and photospheric features near the outer penumbral boundary: penumbral grains (PGs), dark penumbral f…
