The first hours and days of the 2021 explosion of the recurrent symbiotic nova RS Ophiuchii
Augustin Skopal, Martin Vrašťák, Francois Teyssier +4
The accretion of matter on a massive white dwarf (WD) can lead to repeated nuclear explosions on its surface over a timescale of years to decades. The seventh explosion of the recu…
The Be star omicron Cas is indeed the primary of a triple system
Petr Harmanec, Stephenson Yang, Miroslav Slechta +3
Analysis of radial velocities of two narrow absorption components in the Mg II 4481 A line demonstrated that the secondary of the Be star omicron Cas is indeed a close binary syste…
Disentangling the stellar atmosphere and the focused wind in different accretion states of Cygnus X-1
M. Brigitte, P. Hadrava, B. Kubátová +8
In high-mass X-ray binaries (HMXBs), the compact object accretes the strong stellar wind of an O-B supergiant companion star. X-ray flux variations alter the stellar wind's ionizat…
An IXPE-Led X-ray Spectro-Polarimetric Campaign on the Soft State of Cygnus X-1: X-ray Polarimetric Evidence for Strong Gravitational Lensing
James F. Steiner, Edward Nathan, Kun Hu +134
We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwav…
First detection of a magnetic field in low-luminosity B[e] stars: New scenarios for the nature and evolutionary stages of FS CMa stars
D. Korcakova, F. Sestito, N. Manset +8
We report the first detection of the magnetic field in a star of FS CMa type, a subgroup of objects characterized by the B[e] phenomenon. The split of magnetically sensitive lines…
Long-term, orbital, and rapid variations of the Be star V923 Aql = HD 183656
M. Wolf, P. Harmanec, H. Božić +9
We present the latest results of a long-term observational project aimed at observing, collecting from the literature, and homogenising the light, colour, and spectral variations o…
