More than 120 [[BR]]astronomers and engineers worldwide are about to change this. [[BR]]They are working on ANDES the !ArmazoNes high Dispersion [[BR]]Echelle Spectrograph for the E-ELT, which will cover the [[BR]]wavelength range from the U-band to the near infrared providing precision data to understand exoplanet atmospheres in detail or measure the evolution of fundamental constants (Feinstrukturkonstante) back to the beginning of the universe.[[BR]][[BR]]The ANDES instrument will consist of a front end including an [[BR]]adaptive optics system, which is picking up the light in the focal [[BR]]plane. Some fiber feed to three spectrographs - UBV, RI, YJH [[BR]]band - and an optional fourth spectrograph for K-band, where our institute with the APEx-department is most interested in. [[BR]]Therefore, we lead a Phase B study of this K-band spectrograph. Transmission spectroscopy is defining the requirements of the[[BR]] K-band spectrograph for us. Other important constraints are [[BR]]the size (volume) and mass, and the highest possible optical throughput. The decision on whether or not to proceed with [[BR]]the K-band spectrograph will happen after the completion of [[BR]]the current Phase B study of the ANDES instrument sometime[[BR]] in 2024. Hopefully it will not end like in Monty Pythons 'Meaning[[BR]] of life' after just one more mint.[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/WikiStart/att_andes_20220307.pdf Slides: English][[BR]]Questions: German, English || || 14.03.2022 || -- || -- || || '''21.03.2022''' || '''Markus Feldt''' || '''SPHERE+[[BR]][[BR]]'''Since 2015, SPHERE has been providing regular data and has not only enabled the consortium of manufacturers to produce well over 100 publications, but has also actually delivered transformative discoveries in the field of exoplanets and planet-forming disks. In one respect, however, its success has been limited: The instrument, which was conceived as a "planet hunter", has found planets, but the ultimate success has - foreseeably - failed to materialise, despite an enormous amount of observation time. However, 6 years of experience provided valuable information about the limiting factors, which have now been reliably identified, as well as possible remedies. This gave rise to the idea of a "SPHERE+" upgrade - an improvement in spectral resolution, as well as an upgrade of the XAO system with a second stage.[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/WikiStart/att-sphere_plus.pdf Slides: English][[BR]]Questions: German, English || || 28.03.2022 || -- || -- || || '''04.04.2022''' || '''Andreas Bichler (!OptoSigma)''' || '''!OptoSigma - From University partner to space explorer'''[[BR]][[BR]]!OptoSigma (jap.: !SigmaKoki) is a global leader in developing and manufacturing high-quality photonic components.
