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…
Unified approach to QED in arbitrary linear media
Christian Raabe, Stefan Scheel, Dirk-Gunnar Welsch
We give a unified approach to macroscopic QED in arbitrary linearly responding media, based on the quite general, nonlocal form of the conductivity tensor as it can be introduced w…
Local-field correction to one- and two-atom van der Waals interactions
Agnes Sambale, Stefan Yoshi Buhmann, Dirk-Gunnar Welsch +1
Based on macroscopic quantum electrodynamics in linearly and causally responding media, we study the local-field corrected van der Waals potentials and forces for unpolarized groun…
Nonperturbative corrections to 4D string theory effective actions from SL(2,Z) duality and supersymmetry
Daniel Robles-Llana, Martin Rocek, Frank Saueressig +2
We find the D(-1) and D1-brane instanton contributions to the hypermultiplet moduli space of type IIB string compactifications on Calabi-Yau threefolds. These combine with known pe…
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…
