Orbital and Physical Properties of the Pleiades Binary 27 Tau (Atlas)
G. Torres, A. Tkachenko, K. Pavlovski +12
We report new spectroscopic and interferometric observations of the Pleiades binary star Atlas, which played an important role nearly three decades ago in settling the debate over…
Precise Age For The Binary HD 21278 In The Young Alpha Persei Cluster
Christopher A. Danner, Eric L. Sandquist, Gail H. Schaefer +14
We present a study of the double-lined spectroscopic binary HD 21278 that contains one of the brightest main sequence stars in the young Persei open cluster. We analyzed new sp…
Spatially resolved centrifugal magnetosphere caught in motion around the secondary component of Oph A
R. Klement, M. E. Shultz, Th. Rivinius
The recently discovered spectroscopic binary Oph A is a rare magnetic hot binary system composed of two early B-type stars, comprising a non-magnetic primary (Aa) and a slightl…
Binary stars take what they get: Evidence for Efficient Mass Transfer from Stripped Stars with Rapidly Rotating Companions
Thibault Lechien, Selma E. de Mink, Ruggero Valli +5
Binary stars and their interactions shape the formation of compact binaries, supernovae, and gravitational wave sources. The efficiency of mass transfer - the fraction of mass reta…
VLTI/GRAVITY enables the determination of the first dynamical masses of a classical Be + stripped and bloated pre-subdwarf binary
R. Klement, Th. Rivinius, D. Baade +7
HR~6819 is the first post-mass transfer binary system composed of a classical Be star and a bloated pre-subdwarf stripped star directly confirmed by interferometry. While the Be st…
