The European Solar Telescope
C. Quintero Noda, R. Schlichenmaier, L. R. Bellot Rubio +14
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design…
Spectropolarimetric Observations of an Arch Filament System with GREGOR
H. Balthasar, P. Gömöry, S. J. González Manrique +16
We observed an arch filament system (AFS) in a sunspot group with the GREGOR Infrared Spectrograph attached to the GREGOR solar telescope. The AFS was located between the leading s…
Flows in and around active region NOAA12118 observed with the GREGOR solar telescope and SDO/HMI
M. Verma, C. Denker, H. Balthasar +28
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 sunspots. High spatial…
The GREGOR solar telescope on Tenerife
Wolfgang Schmidt, Oskar von der Lühe, Reiner Volkmer +14
2011 was a successful year for the GREGOR project. The telescope was finally completed in May with the installation of the 1.5-meter primary mirror. The installation of the first-l…
Optical configuration and analysis of the AMBER/VLTI instrument
S. Robbe-Dubois, S. Lagarde, R. G. Petrov +23
This paper describes the design goals and engineering efforts that led to the realization of AMBER (Astronomical Multi BEam combineR) and to the achievement of its present performa…
An asymmetry detected in the disk of Kappa CMa with the AMBER/VLTI
Anthony Meilland, Florentin Millour, Philippe Stee +7
Aims. We study the geometry and kinematics of the circumstellar environment of the Be star Kappa CMa in the Br gamma emission line and its nearby continuum. Methods. We use the VLT…
