Discovery of a binary-origin classical Cepheid in a binary system with a 59-day orbital period
Bogumił Pilecki, Ian B. Thompson, Felipe Espinoza-Arancibia +8
We report the discovery of a surprising binary configuration of the double-mode Cepheid OGLE-LMC-CEP-1347 pulsating in the first (P_1=0.690d) and second overtone (P_2=0.556d) modes…
Cepheids with giant companions. I. Revealing a numerous population of double-lined binary Cepheids
Bogumił Pilecki, Grzegorz Pietrzyński, Richard I. Anderson +5
Masses of classical Cepheids of 3 to 11 M are predicted by theory but those measured, clump between 3.6 and 5 M. As a result, their mass-luminosity relation is poorly…
TOI 694 b and TIC 220568520 b: Two Low-Mass Companions Near the Hydrogen Burning Mass Limit Orbiting Sun-like Stars
Ismael Mireles, Avi Shporer, Nolan Grieves +40
We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exo…
X-ray Observations of the Peculiar Cepheid V473 Lyr Identify A Low-Mass Companion
Nancy Remage Evans, Ignazio Pillitteri, Laszlo Molnar +17
V473 Lyr is a classical Cepheid which is unique in having substantial amplitude variations with a period of approximately 3.3 years, thought to be similar to the Blazhko variations…
The EBLM Project VI. The mass and radius of five low-mass stars in F+M binaries discovered by the WASP survey
S. Gill, P. F. L. Maxted, J. A. Evans +27
Some M-dwarfs around F-/G-type stars have been measured to be hotter and larger than predicted by stellar evolution models. Inconsistencies between observations and models need add…
Are the orbital poles of binary stars in the solar neighbourhood anisotropically distributed?
J-L. Agati, D. Bonneau, A. Jorissen +4
We test whether or not the orbital poles of the systems in the solar neighbourhood are isotropically distributed on the celestial sphere. The problem is plagued by the ambiguity on…
