KEPLER'S FIRST ROCKY PLANET: KEPLER-10b*
NASA's Kepler Mission uses transit photometry to determine the frequency of Earth-size planets in or near the habitable zone of Sun-like stars. The mission reached a milestone toward meeting thatExpand

SUNRISE/IMaX OBSERVATIONS OF CONVECTIVELY DRIVEN VORTEX FLOWS IN THE SUN
We characterize the observational properties of the convectively driven vortex flows recently discovered on the quiet Sun, using magnetograms, Dopplergrams, and images obtained with the 1 mExpand

PERSISTENT MAGNETIC WREATHS IN A RAPIDLY ROTATING SUN
When our Sun was young it rotated much more rapidly than now. Observations of young, rapidly rotating stars indicate that many possess substantial magnetic activity and strong axisymmetric magneticExpand

Magnetic cycles in a convective dynamo simulation of a young solar-type star
Young solar-type stars rotate rapidly and many are magnetically active. Some appear to undergo magnetic cycles similar to the 22 yr solar activity cycle. We conduct simulations of dynamo action inExpand

Magnetic field strength of active region filaments
Aims. We study the vector magnetic field of a filament observed over a compact active region neutral line. Methods. Spectropolarimetric data acquired with TIP-II (VTT, Tenerife, Spain) of the 10 830Expand

MAGNETO-THERMOHALINE MIXING IN RED GIANTS
We revise a magnetic buoyancy model that has recently been proposed as a mechanism for extra mixing in the radiative zones of low-mass red giants. The most important revision is our accounting of theExpand

An active region filament studied simultaneously in the chromosphere and photosphere - I. Magnetic structure
Aims. A thorough multiwavelength, multiheight study of the vector magnetic field in a compact active region filament (NOAA 10781) on 2005 July 3 and 5 is presented. We suggest an evolutionaryExpand

An active region filament studied simultaneously in the chromosphere and photosphere - II. Doppler velocities
Context. Paper I presents the magnetic structure, inferred for the photosphere and the chromosphere, of a filament that developed in active region (AR) NOAA 10781, observed on 2005 July 3 and July 5.Expand

Strong Dynamo Action in Rapidly Rotating Suns
Stellar dynamos are driven by complex couplings between rotation and turbulent convection, which drive global‐scale flows and build and rebuild stellar magnetic fields. When stars like our sun areExpand

Rapid rotation, active nests of convection and global-scale flows in solar-likestars
In the solar convection zone, rotation couples with intensely turbulent convection to build global-scale flows of differential rotation and meridional circulation. Our sun must have rotated moreExpand
