Detecting non-uniform period spacings in the Kepler photometry of gamma Doradus stars: methodology and case studies
T. Van Reeth, A. Tkachenko, C. Aerts +9
Context. The analysis of stellar oscillations is one of the most reliable ways to probe stellar interiors. Recent space missions such as Kepler have provided us with an opportunity…
On the Raman O VI and related lines in classical novae
Steven N. Shore, Ivan De Gennaro Aquino, Simone Scaringi +1
We critically examine the recent claimed detection of Raman scattered O VI at around 6830Å in the iron curtain stage spectra of the classical CO nova V339 Del. The observed line va…
IP Eri: A surprising long-period binary system hosting a He white dwarf
T. Merle, A. Jorissen, T. Masseron +3
We determine the orbital elements for the K0 IV + white dwarf (WD) system IP Eri, which appears to have a surprisingly long period of 1071 d and a significant eccentricity of 0.25.…
Herschel/PACS observations of the 69 band of crystalline olivine around evolved stars
J. A. D. L. Blommaert, B. L. de Vries, L. B. F. M. Waters +15
We present 48 Herschel/PACS spectra of evolved stars in the wavelength range of 67-72 m. This wavelength range covers the 69 m band of crystalline olivine ($\text{Mg}_{2-2x}\…
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…
Monitoring evolved stars for binarity with the HERMES spectrograph
N. Gorlova, H. Van Winckel, J. Vos +4
Binarity is often invoked to explain peculiarities that can not be explained by the standard theory of stellar evolution. Detecting orbital motion via the Doppler effect is the bes…
