Comet-like mineralogy of olivine crystals in an extrasolar proto-Kuiper belt
B. L. de Vries, B. Acke, J. A. D. L. Blommaert +20
Some planetary systems harbour debris disks containing planetesimals such as asteroids and comets. Collisions between such bodies produce small dust particles, the spectral feature…
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…
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…
A background galaxy in the field of the beta Pic debris disk
S. Regibo, B. Vandenbussche, C. Waelkens +9
Herschel images in six photometric bands show the thermal emission of the debris disk surrounding beta Pic. In the three PACS bands at 70 micron, 100 micron and 160 micron and in t…
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…
The dynamic atmospheres of Mira stars: comparing the CODEX models to PTI time series of TU And
M. Hillen, T. Verhoelst, P. Degroote +2
Our comprehension of stellar evolution on the AGB still faces many difficulties. To improve on this, a quantified understanding of large-amplitude pulsator atmospheres and interpre…
