Determination of the position angle of stellar spin axes
Anna-Lea Lesage, Guenter Wiedemann
Measuring the stellar position angle provides valuable information on binary stellar formation or stellar spin axis evolution. We aim to develop a method for determining the absolu…
Solar Hidden Photon Search
Matthias Schwarz, Axel Lindner, Javier Redondo +2
The Solar Hidden Photon Search (SHIPS) is a joint astroparticle project of the Hamburger Sternwarte and DESY. The main target is to detect the solar emission of a new species of pa…
The CRIRES Search for Planets Around the Lowest-Mass Stars. II. The Proposed Giant Planet Orbiting VB10 Does Not Exist
Jacob L. Bean, Andreas Seifahrt, Henrik Hartman +5
We present high-precision relative radial velocities of the very low-mass star VB10 that were obtained over a time span of 0.61 yr as part of an ongoing search for planets around s…
CARMENES: Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph
A. Quirrenbach, P. J. Amado, H. Mandel +55
CARMENES, Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph, is a study for a next-generation instrument for the 3.5m Calar A…
The CRIRES Search for Planets Around the Lowest-Mass Stars. I. High-Precision Near-Infrared Radial Velocities with an Ammonia Gas Cell
Jacob L. Bean, Andreas Seifahrt, Henrik Hartman +5
Radial velocities measured from near-infrared spectra are a potentially powerful tool to search for planets around cool stars and sub-stellar objects. However, no technique current…
Production and Detection of Axion-Like Particles in a HERA Dipole Magnet - Letter-of-Intent for the ALPS experiment -
Klaus Ehret, Maik Frede, Ernst-Axel Knabbe +6
Recently, the PVLAS collaboration has reported evidence for an anomalous rotation of the polarization of light in vacuum in the presence of a transverse magnetic field. This may be…
