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…
GQ Lup and its common proper motion companion
M. Mugrauer, R. Neuhaeuser
Recently, Neuhaeuser et al. (2005) presented evidence for a sub-stellar, common proper motion companion to GQ Lup. With two theoretical mass estimates, both below the Deuterium bur…
Direct detection of exo-planets: GQ Lupi
Ralph Neuhaeuser, Eike Guenther, Peter Hauschildt
We present a comparison of our VLT/NACO K-band spectrum of the GQ Lupi companion with the new GAIA-dusty model atmosphere grid for T=2000 and 2900 K and log g from 0 to 4. Then, we…
