Full orbital solution and dynamical masses for a new shell-Be + sdOB binary AN Col

R. Klement, Th. Rivinius, A. C. Carciofi +4

AN~Col is a shell Be star that has shown transient spectral features caused by a hot, evolved companion on a months-long orbit. If confirmed, this would place it among the growing…

Circini: A massive hierarchical triple system with an eclipsing binary

J. Švrčková, P. Harmanec, R. Klement +6

Circini is known to be a massive multiple system containing a 3.9 d inner eclipsing binary in a slightly elliptical orbit exhibiting slow apsidal motion and a distant tertiary…

Discovery of the binary nature of the magnetospheric B-type star Oph A

M. E. Shultz, I. Berry, D. Bohlender +11

The nearby B-type star Oph A was recently identified as a rapidly rotating magnetic B-type star with variable radio and X-ray emission consistent with a magnetospheric origin.…

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…

The birth of Be star disks I. From localized ejection to circularization

J. Labadie-Bartz, A. C. Carciofi, A. C. Rubio +35

Classical Be stars are well known to eject mass, but the details governing the initial distribution and evolution of this matter into a disk are poorly constrained by observations.…

Newborn Be star systems observed shortly after mass transfer

Th. Rivinius, R. Klement, S. D. Chojnowski +24

Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been discovere…
