The AstraLux large M dwarf survey
Felix Hormuth, Wolfgang Brandner, Markus Janson +2
AstraLux is the Lucky Imaging camera for the Calar Alto 2.2-m telescope and the 3.5-m NTT at La Silla. It allows nearly diffraction limited imaging in the SDSS i' and z' bands of o…
A comprehensive examination of the Eps Eri system -- Verification of a 4 micron narrow-band high-contrast imaging approach for planet searches
Markus Janson, Sabine Reffert, Wolfgang Brandner +3
Due to its proximity, youth, and solar-like characteristics with a spectral type of K2V, Eps Eri is one of the most extensively studied systems in an extrasolar planet context. Bas…
Integral field spectroscopy of L 449-1 -- A test case for spectral differential imaging with SINFONI
Markus Janson, Wolfgang Brandner, Thomas Henning
Spectral differential imaging is an increasingly used technique for ground-based direct imaging searches for brown dwarf and planetary mass companions to stars. The technique takes…
A Survey for Massive Giant Planets in Debris Disks with Evacuated Inner Cavities
D. Apai, M. Janson, A. Moro-Martin +9
The commonality of collisionally replenished debris around main sequence stars suggests that minor bodies are frequent around Sun-like stars. Whether or not debris disks in general…
A novel L-band imaging search for giant planets in the Tucana and Beta Pictoris moving groups
Markus Kasper, Daniel Apai, Markus Janson +1
The paper presents results from a small survey of 22 young, nearby stars that was designed to detect substellar companions and ultimately giant extrasolar planets down to Jupiter m…
NACO-SDI direct imaging search for the exoplanet Eps Eri b
Markus Janson, Wolfgang Brandner, Thomas Henning +13
The active K2V star Eri hosts the most nearby known extrasolar planet. With an angular separation of about 1" on average, and an age of a few to several hundred Myrs, Eri b…
