On-sky Fibre-Target-Alignment of the 4MOST instrument: calibration and performance
Roland Winkler, Weijia Sun, Daniel Sablowski +9
The 4-metre Multi-Object Spectroscopic Telescope (4MOST) is a new wide-field, fibre-fed spectroscopic survey facility for the VISTA telescope at ESOs Paranal Observatory. The instr…
VPNEP: Detailed characterization of TESS targets around the Northern Ecliptic Pole
K. G. Strassmeier, M. Weber, D. Gruner +13
We embarked on a high-resolution optical spectroscopic survey of bright Transiting Exoplanet Survey Satellite (TESS) stars around the Northern Ecliptic Pole (NEP), dubbed the Vatic…
The various accretion modes of AM Herculis: Clues from multi-wavelength observations in high accretion states
A. D. Schwope, H. Worpel, I. Traulsen +1
We report on XMM-Newton and NuSTAR X-ray observations of the prototypical polar, AM Herculis, supported by ground-based photometry and spectroscopy, all obtained in high accretion…
An extensive spectroscopic time series of three Wolf-Rayet stars -- II. A search for wind asymmetries in the dust-forming WC7 binary WR137
N. St-Louis, C. Piaulet, N. D. Richardson +39
We present the results of a four-month, spectroscopic campaign of the Wolf-Rayet dust-making binary, WR137. We detect only small-amplitude, random variability in the CIII5696 emiss…
The Wolf-Rayet binaries of the nitrogen sequence in the Large Magellanic Cloud: spectroscopy, orbital analysis, formation, and evolution
T. Shenar, D. P. Sablowski, R. Hainich +11
Massive Wolf-Rayet (WR) stars dominate the radiative and mechanical energy budget of galaxies and probe a critical phase in the evolution of massive stars prior to core-collapse. I…
Carbon 12C/13C isotope ratio of alpha Aurigae revised
Daniel P. Sablowski, Silva Järvinen, Ilya Ilyin +1
Context. Capella (α Aur) is one of the few binaries in the sky with two cool giant stars. With spectral types of G8III and G0III, the two components appear at different but distinc…
