Shape parameters of Galactic open clusters
N. V. Kharchenko, P. Berczik, M. I. Petrov +4
(abridged) In this paper we derive observed and modelled shape parameters (apparent ellipticity and orientation of the ellipse) of 650 Galactic open clusters identified in the ASCC…
Discovery of very low amplitude 9-minute multiperiodic pulsations in the magnetic Ap star HD 75445
O. Kochukhov, S. Bagnulo, G. Lo Curto +1
We present our discovery of pulsational radial-velocity variations in the cool Ap star HD 75445, an object spectroscopically similar to the bright, rapidly-oscillating Ap (roAp) st…
MOST photometry of the enigmatic PMS pulsator HD 142666
K. Zwintz, T. Kallinger, D. B. Guenther +11
We present precise photometry of the pulsating Herbig Ae star HD 142666 obtained in two consecutive years with the MOST (Microvariability & Oscilations of STars) satellite. Previou…
On the morphology of the compact dust shell in the symbiotic system HM Sagittae
Stéphane Sacuto, Olivier Chesneau
The symbiotic system HM Sagittae consists of a Mira star and a secondary White Dwarf component. The dust content of the system was severely affected by the nova outburst in 1975, w…
Toward mode selection in Delta Scuti stars: Regularities in observed and theoretical frequency spectra
M. Breger, P. Lenz, A. A. Pamyatnykh
Only a fraction of the theoretically predicted nonradial pulsation modes have so far been observed in Delta Scuti stars. Nevertheless, the large number of frequencies detected in r…
Modeling the Local Warm/Hot Bubble
Dieter Breitschwerdt, Miguel A. de Avillez, Verena Baumgartner
In this paper we review the modeling of the Local Bubble (LB) with special emphasis on the progress we have made since the last major conference "The Local Bubble and Beyond (I)" h…
