A Tale of Two Stars: Interferometric Studies of Post-AGB Binaries
M. Hillen, J. Menu, B. de Vries +7
Binaries with circumbinary disks are commonly found among optically bright post-AGB stars. Although clearly linked to binary interaction processes, the formation, evolution and fat…
Detection of solar-like oscillations in the bright red giant stars Psc and Tau from a 190-day high-precision spectroscopic multisite campaign
P. G. Beck, E. Kambe, M. Hillen +35
Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were t…
An interferometric study of the post-AGB binary 89 Herculis. II Radiative transfer models of the circumbinary disk
M. Hillen, J. Menu, H. Van Winckel +6
The presence of disks and outflows is widespread among post-AGB binaries. In the first paper of this series, a surprisingly large fraction of optical light was found to be resolved…
A PIONIER View on Mass-Transferring Red Giants
Henri M. J. Boffin, Nicolas Blind, Michel Hillen +3
Symbiotic stars display absorption lines of a cool red giant together with emission lines of a nebula ionized by a hotter star, indicative of an active binary star system in which…
Roche-lobe filling factor of mass-transferring red giants - the PIONIER view
Henri M. J. Boffin, M. Hillen, J. P. Berger +5
Using the PIONIER visitor instrument that combines the light of the four Auxiliary Telescopes of ESO's Very Large Telescope Interferometer, we measure precisely the diameters of se…
