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…
Observational evidence for composite grains in an AGB outflow: MgS in the extreme carbon star LL Peg
R. Lombaert, B. L. de Vries, A. de Koter +5
The broad 30 μm feature in carbon stars is commonly attributed to MgS dust particles. However, reproducing the 30 μm feature with homogeneous MgS grains would require much more sul…
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.…
Herschel images of Fomalhaut. An extrasolar Kuiper Belt at the height of its dynamical activity
B. Acke, M. Min, C. Dominik +33
Fomalhaut is a young, nearby star that is suspected to harbor an infant planetary system, interspersed with one or more belts of dusty debris. We present far-infrared images obtain…
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…
