Extensive study of HD 25558, a long-period double-lined binary with two SPB components
Á. Sódor, P. De Cat, D. J. Wright +33
We carried out an extensive observational study of the Slowly Pulsating B (SPB) star, HD 25558. The ~2000 spectra obtained at different observatories, the ground-based and MOST sat…
Pulsating red giant stars in eccentric binary systems discovered from Kepler space-based photometry
P. G. Beck, K. Hambleton, J. Vos +30
The unparalleled photometric data obtained by NASA's Kepler space telescope led to an improved understanding of red giant stars and binary stars. Seismology allows us to constrain…
The problematically short superwind of OH/IR stars - Probing the outflow with the 69 μm spectral band of forsterite
B. L. de Vries, J. A. D. L. Blommaert, L. B. F. M. Waters +4
Spectra of OH/IR stars show prominent spectral bands of crystalline olivine (MgFeSiO). To learn more about the timescale of the outflows of OH/IR stars, w…
A search for pulsations in the HgMn star HD 45975 with CoRoT photometry and ground-based spectroscopy
T. Morel, M. Briquet, M. Auvergne +28
The existence of pulsations in HgMn stars is still being debated. To provide the first unambiguous observational detection of pulsations in this class of chemically peculiar object…
Studies of Variability in Proto-Planetary Nebulae: II. Light and Velocity Curve Analyses of Iras 22272+5435 and 22223+4327
Bruce J. Hrivnak, Wenxian Lu, Julius Sperauskas +3
We have carried out a detailed observational study of the light, color, and velocity variations of two bright, carbon-rich proto-planetary nebulae, IRAS 22223+4327 and 22272+5435.…
HERMES at Mercator, competitive high-resolution spectroscopy with a small telescope
Gert Raskin, Hans Van Winckel
HERMES, a fibre-fed high-resolution (R=85000) echelle spectrograph with good stability and excellent throughput, is the work-horse instrument of the 1.2-m Mercator telescope on La…
