Multiplicity-Study of Exoplanet Host Stars
M. Mugrauer, R. Neuhäuser, T. Mazeh +1
We carry out a systematic search campaign for wide companions of exoplanet host stars to study their multiplicity and its influence on the long-term stability and the orbital param…
The low-mass companion of GQ Lup
E. W. Guenther, R. Neuhaeuser, G. Wuchterl +3
Using NACO on the VLT in the imaging mode we have detected an object at a distance of only 0.7 arcsec from GQ Lup. The object turns out to be co-moving. We have taken two K-band sp…
New brown dwarf companions to dM(e) stars
Andreas Seifahrt, Markus Mugrauer, Manuela Wiese +2
We present new astrometric and spectroscopic data to confirm two new M/L dwarf systems, G124-62 and LHS5166, and discuss the nature of a third system (LP261-75). Age and thus mass…
Four new wide binaries among exoplanet host stars
M. Mugrauer, R. Neuhaeuser, A. Seifahrt +2
In our ongoing survey for wide (sub)stellar companions of exoplanet host stars we have found 4 new co-moving stellar companions of the stars HD114729, HD16141, HD196050 and HD21324…
Gl86B: a white dwarf orbits an exoplanet host star
M. Mugrauer, R. Neuhaeuser
In this letter we present our first high contrast NACO/SDI observations of the exoplanet host star Gl86 and results from NACO spectroscopy. Els et al. (2001) found a faint co-movin…
