The orbits of subdwarf B + main-sequence binaries. I: The sdB+G0 system PG 1104+243
J. Vos, R. H. Östensen, P. Degroote +18
The predicted orbital period histogram of an sdB population is bimodal with a peak at short (< 10 days) and long (> 250 days) periods. Observationally, there are many short-period…
Discovery of a TiO emission band in the infrared spectrum of the S star NP Aurigae
K. Smolders, T. Verhoelst, P. Neyskens +10
We report on the discovery of an infrared emission band in the Spitzer spectrum of the S-type AGB star NP Aurigae that is caused by TiO molecules in the circumstellar environment.…
Detection of gravity modes in the massive binary V380 Cyg from Kepler spacebased photometry and high-resolution spectroscopy
A. Tkachenko, C. Aerts, K. Pavlovski +17
We report the discovery of low-amplitude gravity-mode oscillations in the massive binary star V380 Cyg, from 180 d of Kepler custom-aperture space photometry and 5 months of high-r…
The Spitzer Spectroscopic Survey of S-type Stars
K. Smolders, P. Neyskens, J. A. D. L. Blommaert +28
S-type AGB stars are thought to be in the transitional phase between M-type and C-type AGB stars. Because of their peculiar chemical composition, one may expect a strong influence…
