Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse
Morgan MacLeod, Sarah Blunt, Robert J. De Rosa +10
We examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion t…
The Great Dimming of Betelgeuse: the photosphere as revealed by tomography over the past 15 years
Daniel Jadlovský, Thomas Granzer, Michael Weber +6
Betelgeuse, a red supergiant star of semi-regular variability, reached a historical minimum brightness in February 2020, known as the Great Dimming. Even though the brightness has…
HIRES, the high-resolution spectrograph for the ELT
Alessandro Marconi, Manuel Abreu, Vardan Adibekyan +99
HIRES will be the high-resolution spectrograph of the European Extremely Large Telescope at optical and near-infrared wavelengths. It consists of three fibre-fed spectrographs prov…
High-resolution spectroscopy and spectropolarimetry of the total lunar eclipse January 2019
K. G. Strassmeier, I. Ilyin, E. Keles +5
Observations of the Earthshine off the Moon allow for the unique opportunity to measure the large-scale Earth atmosphere. Another opportunity is realized during a total lunar eclip…
PEPSI deep spectra. II. Gaia benchmark stars and other M-K standards
K. G. Strassmeier, I. Ilyin, M. Weber
We provide a homogeneous library of high-resolution, high-S/N spectra for 48 bright AFGKM stars, some of them approaching the quality of solar-flux spectra. Our sample includes the…
