Binary central stars of planetary nebulae with long orbits: the radial velocity orbit of BD+33.2642 (PN G052.7+50.7) and the orbital motion of HD112313 (PN LoTr5)
Hans Van Winckel, Alain Jorissen, Katrina Exter +4
We study the impact of binary interaction processes on the evolution of low- and intermediate-mass stars using long-term monitoring of their radial velocity. Here we report on our…
Modelling the asymmetric wind of the luminous blue variable binary MWC 314
A. Lobel, J. H. Groh, C. Martayan +12
We present a spectroscopic analysis of MWC 314, a luminous blue variable (LBV) candidate with an extended bipolar nebula. The detailed spectroscopic variability is investigated to…
Chemical surface inhomogeneities in late B-type stars with Hg and Mn peculiarity I Spot evolution in HD 11753 on short and long time scales
H. Korhonen, J. F. Gonzalez, M. Briquet +7
Aims: Time series of high-resolution spectra of the late B-type star HD 11753 exhibiting HgMn chemical peculiarity are used to study the surface distribution of different chemical…
Time resolved spectroscopy of BD+46 442: gas streams and jet creation in a newly discovered evolved binary with a disk
N. Gorlova, H. Van Winckel, C. Gielen +9
Previous studies have shown that many post-AGB stars with dusty disks are associated with single-lined binary stars. To verify the binarity hypothesis on a larger sample, we starte…
Mass ratio from Doppler beaming and Rømer delay versus ellipsoidal modulation in the Kepler data of KOI-74
S. Bloemen, T. R. Marsh, P. Degroote +18
We present a light curve analysis and radial velocity study of KOI-74, an eclipsing A star + white dwarf binary with a 5.2 day orbit. Aside from new spectroscopy covering the orbit…
Modeling the Asymmetric Wind of Massive LBV Binary MWC 314
A. Lobel, J. Groh, K. Torres Dozinel +13
Spectroscopic monitoring with Mercator-HERMES over the past two years reveals that MWC 314 is a massive binary system composed of an early B-type primary LBV star and a less-lumino…
The evolutionary state of Miras with changing pulsation periods
Stefan Uttenthaler, Koen Van Stiphout, Kevin Voet +12
Context: Miras are long-period variables thought to be in the asymptotic giant branch (AGB) phase of evolution. In about one percent of known Miras, the pulsation period is changin…
