Near-IR integral-field spectroscopy of the companion to GQ Lup
Andreas Seifahrt, Ralph Neuhaeuser, Peter H. Hauschildt +1
The first substellar companion of possibly planetary mass around a normal star, GQ Lup, has been directly imaged (Neuhaeuser et al., 2005). Besides the unknown formation history, t…
Direct detection of exoplanet host star companion gamma Cep B and revised masses for both stars and the sub-stellar object
Ralph Neuhaeuser, Markus Mugrauer, Misato Fukagawa +2
The star gamma Cep is known as a single-lined spectroscopic triple system at a distance of 13.8 pc, composed of a K1 III-IV primary star with V = 3.2 mag, a stellar-mass companion…
On the nature of clumps in debris disks
Alexander V. Krivov, Martina Queck, Torsten Löhne +1
The azimuthal substructure observed in some debris disks, as exemplified by epsilon Eridani, is usually attributed to resonances with embedded planets. In a standard scenario, the…
Detectability of planets in wide binaries by ground-based relative astrometry with AO
Ralph Neuhaeuser, Andreas Seifahrt, Tristan Roell +2
Many planet candidates have been detected by radial velocity variations of the primary star; they are planet candidates, because of the unknown orbit inclination. Detection of the…
Multiplicity Study of exoplanet host stars: The HD3651AB system
M. Mugrauer, A. Seifahrt, R. Neuhaeuser +2
We report on new results of our multiplicity study and present our follow-up observations of the recently detected faint companion HD3651B, the first directly imaged T dwarf compan…
The 10 m infrared band of silicate dust: A laboratory study comparing the aerosol and KBr pellet techniques
A. Tamanai, H. Mutschke, J. Blum +1
The profile of the silicate 10 m IR band contains important information about the evolutional stage of dust in circumstellar environments and the possible ongoing process of pla…
