Due to its proximity, youth, and solar-like characteristics with a spectral type of K2V, � Eri is one of the most extensively studied systems in an extrasolar planet context. Based on radial velocity, astrometry, and studies of the structure of its circumstellar debris disk, at least two planetary companion candidates toEri have been inferred in the literature (� Eri b, � Eri c). Some of these methods also hint at additional companions residing in the system. Here we present a new adaptive…

High-contrast imaging of ϵ Eridani with ground-based instruments
epsilon Eridani is one of the nearest solar-type stars. Its proximity and relatively young age allow high-contrast imaging observations to achieve sensitivities to planets at narrow separations down
Imaging Extrasolar Giant Planets
High-contrast adaptive optics (AO) imaging is a powerful technique to probe the architectures of planetary systems from the outside-in and survey the atmospheres of self-luminous giant planets.

Astrometric monitoring of the Sirius binary system over the past century has yielded several predictions for an unseen third system component, the most recent one suggesting a ≲50 MJup object in a
Constraints on the nearby exoplanet ϵ Indi Ab from deep near- and mid-infrared imaging limits
The past decade has seen increasing efforts in detecting and characterising exoplanets using high-contrast imaging in the near- and mid-infrared, which is the optimal wavelength domain for studying

Infrared Non-detection of Fomalhaut b: Implications for the Planet Interpretation
The nearby A4-type star Fomalhaut hosts a debris belt in the form of an eccentric ring, which is thought to be caused by dynamical influence from a giant planet companion. In 2008, a detection of a
Imaging search for the unseen companion to ε Ind A - Improving the detection limits with 4 μm observations
∈ Ind A is one of the nearest Sun-like stars, located only 3.6 pc away. It is known to host a binary brown dwarf companion, ∈ Ind Ba/Bb, at a large projected separation of 6.7 arcmin, but radial
SPITZER/INFRARED ARRAY CAMERA LIMITS TO PLANETARY COMPANIONS OF FOMALHAUT AND ϵ ERIDANI
Fomalhaut and ϵ Eridani are two young, nearby stars that possess extended debris disks whose structures suggest the presence of perturbing planetary objects. With its high sensitivity and stable
