Three-dimensional structure of a sunspot light bridge
T. Felipe, M. Collados, E. Khomenko +26
Active regions are the most prominent manifestations of solar magnetic fields; their generation and dissipation are fundamental problems in solar physics. Light bridges are commonl…
Short-term evolution and coexistence of spots, plages and flare activity on LQ Hydrae
M. Flores Soriano, K. G. Strassmeier
Four months of quasi-simultaneous spectroscopic and photometric observations were used to study the variations of the photometric light curve, the evolution of the chromospheric ac…
Broad-band spectrophotometry of HAT-P-32 b: Search for a scattering signature in the planetary spectrum
M. Mallonn, I. Bernt, E. Herrero +12
Multi-colour broad-band transit observations offer the opportunity to characterise the atmosphere of an extrasolar planet with small- to medium-sized telescopes. One of the most fa…
Transmission spectroscopy of HAT-P-32b with the LBT: confirmation of clouds/hazes in the planetary atmosphere
Matthias Mallonn, Klaus G. Strassmeier
Spectroscopic observations of a transit event of an extrasolar planet offer the opportunity to study the composition of the planetary atmosphere. We observed a transit of the infla…
Rotation periods for cool stars in the 4 Gyr-old open cluster M67, the solar-stellar connection, and the applicability of gyrochronology to at least solar age
Sydney A. Barnes, Joerg Weingrill, Dario Fritzewski +1
We report rotation periods for 20 cool (FGK) main sequence member stars of the 4 Gyr-old open cluster M 67 (= NGC 2682), obtained by analysing data from Campaign 5 of the K2 missio…
The LOFAR Solar Imaging Pipeline and the LOFAR Solar Data Center
Frank Breitling, Gottfried Mann, Christian Vocks +2
LOFAR is a new and sensitive radio interferometer that can be used for dynamic high-resolution imaging spectroscopy at low radio frequencies from 10 to 90 and 110 to 250 MHz. Here…
