Comparing modal noise and FRD of circular and non-circular cross- section fibres
D. P. Sablowski, D. Plüschke, M. Weber +2
Modal noise is a common source of noise introduced to the measurements by optical fibres and is particularly important for fibre-fed spectroscopic instruments, especially for high-…
Broad-band spectrophotometry of the hot Jupiter HAT-P-12b from the near-UV to the near-IR
M. Mallonn, V. Nascimbeni, J. Weingrill +13
The detection of trends or gradients in the transmission spectrum of extrasolar planets is possible with observations at very low spectral resolution. Transit measurements of suffi…
Transmission spectroscopy of the inflated exo-Saturn HAT-P-19b
M. Mallonn, C . von Essen, J. Weingrill +7
We observed the Saturn-mass and Jupiter-sized exoplanet HAT-P-19b to refine its transit parameters and ephemeris as well as to shed first light on its transmission spectrum. We mon…
PEPSI: The high-resolution echelle spectrograph and polarimeter for the Large Binocular Telescope
K. G. Strassmeier, I. Ilyin, A. Järvinen +26
PEPSI is the bench-mounted, two-arm, fibre-fed and stabilized Potsdam Echelle Polarimetric and Spectroscopic Instrument for the 2x8.4 m Large Binocular Telescope (LBT). Three spect…
Large Binocular Telescope view of the atmosphere of GJ1214b
V. Nascimbeni, M. Mallonn, G. Scandariato +8
The atmospheric composition and vertical structure of the super-Earth GJ1214b has been a subject of debate since its discovery in 2009. Recent studies have indicated that high-alti…
Spot evolution on the red giant star XX Triangulum. A starspot-decay analysis based on time-series Doppler imaging
A. Künstler, T. A. Carroll, K. G. Strassmeier
Solar spots appear to decay linearly proportional to their size. The decay rate of solar spots is directly related to magnetic diffusivity, which itself is a key quantity for the l…
