FM stars: A Fourier view of pulsating binary stars, a new technique for measuring radial velocities photometrically [PDF]
, 2012 Some pulsating stars are good clocks. When they are found in binary stars, the frequencies of their luminosity variations are modulated by the Doppler effect caused by orbital motion.

Precise Age for the Binary Star System 12 Com in the Coma Berenices Cluster
The Astronomical Journal, 2023 We present measurements of the interferometrically resolved binary star system 12 Com and the single giant star 31 Com in the cluster Coma Berenices. 12 Com is a double-lined spectroscopic binary system consisting of a G7 giant and an A3 dwarf at the ...

Bayesian analysis of exoplanet and binary orbits
, 2012 We introduce BASE (Bayesian astrometric and spectroscopic exoplanet detection and characterisation tool), a novel program for the combined or separate Bayesian analysis of astrometric and radial-velocity measurements of potential exoplanet hosts and ...

Evolved Eclipsing Binaries and the Age of the Open Cluster NGC 752
The Astronomical Journal, 2022 We present analyses of improved photometric and spectroscopic observations for two detached eclipsing binaries at the turnoff of the open cluster NGC 752: the 1.01 days binary DS And and the 15.53 days BD +37 410. For DS And, we find M _1 = 1.692 ± 0.004

The role of binarity in Wolf-Rayet central stars of planetary nebulae
, 2015 Over a hundred planetary nebulae (PNe) are known to have H-deficient central stars that mimic the spectroscopic appearance of massive Wolf-Rayet stars. The formation of these low-mass Wolf-Rayet stars, denoted [WR] stars, remains poorly understood. While

THREE SPECTROSCOPIC BINARIES IN THE BRIGHT STAR CATALOG SUPPLEMENT [PDF]
Revista Mexicana de Astronomía y Astrofísica, 2019 This paper presents spectroscopic orbits of three binaries, HD 121212, HD 148434 and HD 148912, with evolved primaries and periods of order a year, found in a survey of late-type stars listed in the Supplement to the Yale Bright Star Catalog. All the orbits were determined from observations made with the DAO 1.2-m telescope and coudé spectrograph ...

Binary Fraction in Galactic Star Clusters: FSR 866, NGC 1960, and STOCK 2
The Astronomical JournalThe study of binary stars in different astronomical environments offers insights into the dynamical state of the hosting stellar systems. The binary fraction in fact plays a crucial role in the dynamical evolution of stellar systems, regulating processes
