METIS: The Mid-infrared ELT Imager and Spectrograph
Bernhard Brandl, Felix Bettonvil, Roy van Boekel +13
The Mid-infrared ELT Imager and Spectrograph (METIS) will provide the Extremely Large Telescope (ELT) with a unique window to the thermal- and mid-infrared (3 - 13 microns). Its si…
The Pictoris b Hill sphere transit campaign. Paper I: Photometric limits to dust and rings
M. A. Kenworthy, S. N. Mellon, J. I. Bailey +33
Photometric monitoring of Beta Pictoris in 1981 showed anomalous fluctuations of up to 4% over several days, consistent with foreground material transiting the stellar disk. The su…
Towards a physical understanding of the thermal background in large ground-based telescopes
Leonard Burtscher, Ioannis Politopoulos, Sergio Fernández-Acosta +11
Ground-based thermal-infrared observations have a unique scientific potential, but are also extremely challenging due to the need to accurately subtract the high thermal background…
Using all-sky optical observations for automated orbit determination and prediction for satellites in Low Earth Orbit

Revisiting the pulsational characteristics of the exoplanet host star Pictoris
K. Zwintz, D. R. Reese, C. Neiner +22
Exoplanet properties crucially depend on their host stars' parameters. In case the exoplanet host star shows pulsations, asteroseismology can be used for an improved description of…
