It will provide medium resolution optical/NIR spectroscopy and imaging in a rapid response mode to catch transient astronomical phenomena as fast as possible. The consortium building the instrument is led by the Niels Bohr Institute in Copenhagen who have asked MPIA to provide NTE with our in-house read-out electronics (ROE) for its NIR cameras, i.e. two systems for the imaging and spectroscopic channels plus one spare unit. For us, this is a unique opportunity to bring our ROE to a new facility and continue contributing our special expertise in this field. [[BR]]'''[[BR]](2) CARMENES finds Super-Earth at Barnard's Star - after all''' [[BR]]Up until the 1990s astronomical textbooks claimed that two Jupiter-like planets were orbiting Barnard's star, the closest single star to the Sun. This claim was based on astrometric measurements, which determine the reflex motion of a star caused by the gravitional pull of its planets. More precise observations demonstrated later that these planets do not exist and that the apparent motion of the star had been caused by uncorrected instrumental effects. Actually, until today, the astrometric technique has not found a single exoplanet. Recently though, the well-established radial velocity method has led to a new exoplanet claim around Barnard's star, a cold Super-Earth, the first of its type near the snow line of its system. This difficult discovery was made possible by combining data from seven instruments among which CARMENES was a key player. It will require independent confirmation, expected to come after 2021 from the most precise astrometric measurements ever to be provided by the final release of data from the GAIA satellite.[[BR]][[BR]] Presentation: German[[BR]] [https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2019S1/2019-01-25_NTEBarnard.pdf Slides: English][[BR]]Questions: German, English || |
