Flares and rotation periods of CARMENES M dwarfs from TESS data
CARMENES is a spectrograph built for the 3.5 m telescope at the Calar Alto Observatory. The main aim is to detect low mass planets around M dwarfs. In order to...
Flat-spectrum symmetric radio sources (Augusto+, 2006)
The radio sources listed below were selected from the Jodrell-VLA Astrometric Survey and the Cosmic-Lens All-Sky Survey (part 1) and constitute a (non-complete)...
Flexible design of high-speed readout electronics for astronomical detectors
Hardware design based on 20 MHz transputers, 120 ns first-in, first-out (FIFO) memory, and a 20 MHz counter is discussed. The two transputers are used to...
Flight control software for the wave-front sensor of SUNRISE 1m balloon telescope
This paper describes the flight control software of the wave-front correction system that flew on the 2009 science flight of the Sunrise balloon telescope. The...
Flows along arch filaments observed in the GRIS `very fast spectroscopic mode'
A new generation of solar instruments provides improved spectral, spatial, and temporal resolution, thus facilitating a better understanding of dynamic...
Flows in and around Active Region NOAA12118 Observed with the GREGOR Solar Telescope and SDO/HMI
Accurate measurements of magnetic and velocity fields in and around solar active regions are key to unlocking the mysteries of the formation and the decay of...
Fluctuations in the Activity Curve of the 2002 Leonids
We present observations of the 2002 Leonid meteor shower taken with four intensified video cameras from Teide Observatory (Tenerife Spain) on November 19 2002...
Flux Cancellation in a Decaying Active Region Flux cancellation is observed in many regions on the Sun as internetwork, network and active regions fields. It...
