Ultraviolet spectroscopy reveals a hot and luminous companion to the Be star+black hole candidate MWC 656
Johanna Müller-Horn, Varsha Ramachandran, Kareem El-Badry +11
The Galactic Be star binary MWC 656 was long considered the only known Be star+black hole (BH) system, making it a critical benchmark for models of massive binary evolution and for…
A Decade of Solar High-Fidelity Spectroscopy and Precise Radial Velocities from HARPS-N
X. Dumusque, K. Al Moulla, M. Cretignier +53
We recently released 10 years of HARPS-N solar telescope and the goal of this manuscript is to present the different optimisations made to the data reduction, to describe data cura…
Metallicities from High-Resolution TRES Spectra with uberMS: Performance Benchmarks and Literature Comparison
Emily K. Pass, Phillip A. Cargile, Victoria DiTomasso +7
As the field of exoplanetary astronomy has matured, demand has grown for precise stellar abundances to probe subtle correlations between stellar compositions and planetary demograp…
HIP 15429: A newborn Be star on an eccentric binary orbit
Johanna Müller-Horn, Kareem El-Badry, Hans-Walter Rix +9
We identified a new post-interaction binary, HIP 15429, consisting of a stripped star and a recently formed, rapidly rotating Be star companion ( km/s) sharin…
A population of neutron star candidates in wide orbits from Gaia astrometry
Kareem El-Badry, Hans-Walter Rix, David W. Latham +10
We report discovery and spectroscopic follow-up of 21 astrometric binaries containing solar-type stars and dark companions with masses near 1.4 . The simplest interpreta…
A neutron star candidate in a 2-year orbit
Kareem El-Badry, Joshua D. Simon, Henrique Reggiani +10
We report discovery and characterization of a main-sequence G star orbiting a dark object with mass . The system was discovered via Gaia astrometry and has…
