Discovery of four new EL CVn-type binaries in the Gaia eclipsing binaries [PDF]
, 2023 In this paper, we performed a search for EL CVn-type binaries based on the Gaia and TESS data. Through the combination of the Gaia DR3 eclipsing binary catalogue and the Gaia DR3 spectroscopic binary catalogue, we have identified 13 stars exhibiting EL CVn-like characteristics.

Multiplicity among solar-type stars IV. The CORAVEL radial velocities and the spectroscopic orbits of nearby K dwarfs [PDF]
A&A 619, A81 (2018), 2018 Context. The statistical properties of binary stars are clues for understanding their formation process. A radial velocity survey was carried on amongst nearby G-type stars and the results were published in 1991. Aims. The survey of radial velocity measurements was extended towards K-type stars. Methods.

Low Mass Ratio Contact Binary V410 Aur and V776 Cas - II [PDF]
Journal of Astronomy and Space Sciences, 2005 New BVR CCD light curves of the low mass ratio contact binaries, V410 Aur and V776 Cas, were observed with the 61 cm reflector and a 2K CCD camera at the Sobaeksan Astronomical Observatory.

Orbital Solutions for Two Young, Low-Mass Spectroscopic Binaries in Ophiuchus [PDF]
, 2010 We report the orbital parameters for ROXR1 14 and RX J1622.7-2325Nw, two young, low-mass, and double-lined spectroscopic binaries recently discovered in the Ophiuchus star forming region. Accurate orbital solutions were determined from over a dozen high-resolution spectra taken with the Keck II and Gemini South telescopes.

The Poincaré Pear and Poincaré-Darwin Fission Theory in Astrophysics, 1885-1901
Philosophia Scientiæ, 2023 In the early 1880s, Henri Poincaré discovered an equilibrium figure for uniformly-rotating fluid masses—the pear, or piriform figure—and speculated that in certain circumstances the pear splits into two unequal parts, and provides thereby a model for the

The Value-Added Catalog of ASAS-SN Eclipsing Binaries III: Masses and Radii of Gaia Spectroscopic Binaries [PDF]
, 2022 Masses and radii of stars can be derived by combining eclipsing binary light curves with spectroscopic orbits. In our previous work, we modeled the All-Sky Automated Survey for Supernovae (ASAS-SN) light curves of more than 30,000 detached eclipsing binaries using PHOEBE.

The VLT-FLAMES Tarantula Survey XXII. Multiplicity properties of the B-type stars [PDF]
, 2015 We investigate the multiplicity properties of 408 B-type stars observed in the 30 Doradus region of the Large Magellanic Cloud with multi-epoch spectroscopy from the VLT-FLAMES Tarantula Survey (VFTS).

A Radial Velocity Survey of the Cygnus OB2 Association [PDF]
, 2006 We conducted a radial velocity survey of the Cygnus OB2 Association over a 6 year (1999 - 2005) time interval to search for massive close binaries. During this time we obtained 1139 spectra on 146 OB stars to measure mean systemic radial velocities and ...
