Low mass visual binaries in the solar neighbourhood: The case of HD141272
T. Eisenbeiss, A. Seifahrt, M. Mugrauer +3
We search for stellar and substellar companions of young nearby stars to investigate stellar multiplicity and formation of stellar and substellar companions. We detect common prope…
The multiplicity of exoplanet host stars - Spectroscopic confirmation of the companions GJ3021B and HD27442B, one new planet host triple-star system, and global statistics
M. Mugrauer, R. Neuhaeuser, T. Mazeh
We present new results from our ongoing multiplicity study of exoplanet host stars and present a list of 29 confirmed planet host multiple-star systems. Furthermore, we discuss the…
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…
Evidence for a co-moving sub-stellar companion of GQ Lup
R. Neuhaeuser, E. W. Guenther, G. Wuchterl +3
We present a companion of the \le 2 Myr young classical T Tauri star GQ Lup in the Lupus star forming region at 140 \pm 50 pc from imaging, astrometry, and spectroscopy. With direc…
A low-mass stellar companion of the planet host star HD75289
M. Mugrauer, R. Neuhaeuser, T. Mazeh +2
We report on the detection of a new low-mass stellar companion of HD75289, a G0V star that harbors one known radial-velocity planet (Udry et al. 2000). Comparing an image of 2MASS…
