Spectroscopy of the optical counterpart to Ser X-1
We present William Herschel Telescope (WHT) and Very Large Telescope (VLT) spectroscopy of MM Ser, the optical counterpart to Ser X-1. We deblend the red...
Spectroscopy of the post-AGB star HD 101584 (IRAS 11385-5517)
From an analysis of the spectrum (4000 Ä to 8800 Ä) of HD 101584 it is found that most of the neutral and single ionized metallic lines are in emission. The...
SpectroTranslator: Deep-neural network algorithm for homogenising spectroscopic parameters
Context. In modern Galactic astronomy, stellar spectroscopy plays a pivotal role in complementing large photometric and astrometric surveys and enabling deeper...
Spectrum analysis of bright Kepler late B- to early F-stars
The Kepler satellite mission was designed to search for transiting exoplanets and delivers single band-pass light curves of a huge number of stars observed in...
Spectrum of the cosmic background radiation between 3 MM and 800 microns
The measurements reported were made during a flight to an altitude of 40 km, on Mar. 13, 1974. A polarizing Michelson interferometer cooled, by a liquid helium...
Spectrum radial velocity analyser (SERVAL). High-precision radial velocities and two alternative spectral indicators
Context. The CARMENES survey is a high-precision radial velocity (RV) programme that aims to detect Earth-like planets orbiting low-mass stars. Aims: We develop...
SPECULOOS Northern Observatory: Searching for Red Worlds in the Northern Skies
SPECULOOS is a ground-based transit survey consisting of six identical 1 m robotic telescopes. The immediate goal of the project is to detect temperate...
Spi-OPS: Spitzer and CHEOPS confirm the near-polar orbit of MASCARA-1 b and reveal a hint of dayside reflection
Context. The light curves of tidally locked hot Jupiters transiting fast-rotating, early-type stars are a rich source of information about both the planet and...
SPICA and the Chemical Evolution of Galaxies: The Rise of Metals and Dust
The physical processes driving the chemical evolution of galaxies in the last 11Gyr cannot be understood without directly probing the dust-obscured phase of...
