This design, while previously state-of-the art, leads to systematic errors which is beginning to limit our ability to study some of the most challenging, and consequently most interesting planetary systems. In the era of adaptive optics at large telescope facilities worldwide, it is now possible to inject a diffraction-limited input into single-mode optical fibres to feed next generation RV spectrographs. These have a reduced instrument volume, a stable input source, and can offer improved overall stability and precision for RV over their multi-mode fed counterparts.[[BR]][[BR]]iLocater is a next-generation precision RV spectrograph under development for the Large Binocular Telescope (LBT). It is one of the first astronomical spectrographs to use single-mode fibres for precision radial velocity measurement and will provide high resolution (R~150,000-240,000) NIR spectra in a stable environment. Jonathan Crass will present an overview of the instrument, its current status and novel science programs.[[BR]][[BR]]Presentation: English[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2019S2/2019-10-11_iLocator.pdf Slides: English] [[BR]]Questions: German, English || || 18.10.2019 || || || || '''25.10.2019[[BR]](Time TBD, Room TBD)''' || '''Michael Boehm [[BR]](ISYS Stuttgart)''' || '''Active adjustment of supporting structures for buildings and telescopes[[BR]]'''[[BR]]Abstract[[BR]][[BR]]Presentation: German[[BR]]Slides: English [[BR]]Questions: German, English || || 01.11.2019 || -- || All Saints || || 08.11.2019 || || || || 15.11.2019 || || || || '''22.11.2019[[BR]](Time TBD, Room TBD)''' || ''' Prof. Dr. Andreas Heinrich (Aalen University)''' || '''Additive Manufacturing of Active and Passive Optical Components[[BR]]'''[[BR]]Abstract[[BR]][[BR]]Presentation: German[[BR]] Slides: English [[BR]]Questions: German, English || || 29.11.2019 || || || || '''06.12.2019 [[BR]](Time TBD, Room TBD)''' || '''Zoltan Hubert [[BR]](University of Grenoble)''' || '''MAORY after the redesign[[BR]][[BR]]'''Abstract[[BR]][[BR]]Presentation: German[[BR]] Slides: English [[BR]]Questions: German, English || || 13.12.2019 || || || || 20.12.2019 || || Last talk before Christmas Break || || 27.12.2019 || -- || Christmas Break || '''Preview:''' DD.MM.YYYY - Speaker: Title '''Postview:''' [wiki:OldPresentations2014S2 Presentations from 12.09. - 31.12.2014] [wiki:OldPresentations2015S1 Presentations from 01.01. - 31.07.2015] [wiki:OldPresentations2015S2 Presentations from 01.08. - 31.12.2015] [wiki:OldPresentations2016S1 Presentations from 01.01. - 31.07.2016] [wiki:OldPresentations2016S2 Presentations from 01.08. - 31.12.2016] [wiki:OldPresentations2017S1 Presentations from 01.01. - 31.07.2017] [wiki:OldPresentations2017S2 Presentations from 01.08. - 31.12.2017] [wiki:OldPresentations2018S1 Presentations from 01.01. - 31.07.2018] [wiki:OldPresentations2018S2 Presentations from 01.08. - 31.12.2018] [wiki:OldPresentations2019S1 Presentations from 01.01. - 31.07.2019] [wiki:OldPresentations2019S2 Presentations 2019S2]
