Spectral and orbital characterisation of the directly imaged giant planet HIP 65426 b
A. C. Cheetham, M. Samland, S. S. Brems +38
HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new and observations of the planet from the NACO instr…
The VLTI/MIDI survey of massive young stellar objects - Sounding the inner regions around intermediate- and high-mass young stars using mid-infrared interferometry
Paul A. Boley, Hendrik Linz, Roy van Boekel +10
We aim to characterize the distribution and composition of circumstellar material around young massive stars, and to investigate exactly which physical structures in these objects…
Improved radial velocity orbit of the young binary brown dwarf candidate ChaHa8
V. Joergens, A. Mueller, S. Reffert
The very young brown dwarf candidate ChaHa8 was recently discovered to have a close (~1AU) companion by means of radial velocity monitoring. We present additional radial velocity d…
Discovery of 18 Jupiter mass RV companion orbiting the brown dwarf candidate ChaHa8
Viki Joergens, Andre Mueller
We report the discovery of a 16-20 Jupiter mass radial velocity companion around the very young (3 Myr) brown dwarf candidate ChaHa8. Based on high-resolution echelle spectra of Ch…
Non-monotonic orbital velocity profiles around rapidly rotating Kerr-(anti-)de Sitter black holes
Andreas Mueller, Bernd Aschenbach
It has been recently demonstrated that the orbital velocity profile around Kerr black holes in the equatorial plane as observed in the locally non-rotating frame exhibits a non-mon…
The onset of General Relativity: Gravitationally redshifted emission lines
Andreas Mueller
We study and quantify gravitational redshift by means of relativistic ray tracing simulations of emission lines. The emitter model is based on thin, Keplerian rotating rings in the…
