Tomography of Galactic star-forming regions and spiral arms with the Square Kilometer Array
Laurent Loinard, Mark Thompson, Melvin Hoare +12
Very Long Baseline Interferometry (VLBI) at radio wavelengths can provide astrometry accurate to 10 micro-arcseconds or better (i.e. better than the target GAIA accuracy) without b…
The Magnetic Fields at the Surface of Active Single G-K Giants
M. Aurière, R. Konstantinova-Antova, C. Charbonnel +15
We investigate the magnetic field at the surface of 48 red giants selected as promising for detection of Stokes V Zeeman signatures in their spectral lines. We use the spectropolar…
A Chandra Observation of the Eclipsing Wolf-Rayet Binary CQ Cep
S. L. Skinner, S. A. Zhekov, M. Guedel +1
The short-period (1.64 d) near-contact eclipsing WN6+O9 binary system CQ Cep provides an ideal laboratory for testing the predictions of X-ray colliding wind shock theory at close…
Observations of Cepheids with the MOST satellite: Contrast between Pulsation Modes
N. R. Evans, R. Szabó, A. Derekas +10
The quantity and quality of satellite photometric data strings is revealing details in Cepheid variation at very low levels. Specifically, we observed a Cepheid pulsating in the fu…
Period -- mass-loss rate relation of Miras with and without technetium
Stefan Uttenthaler
We present the discovery that Mira variables separate in two distinct sequences in a near- to mid-IR color versus pulsation period diagram, if a distinction is made with respect to…
The role of turbulent pressure as a coherent pulsational driving mechanism: the case of the delta Scuti star HD 187547
V. Antoci, M. Cunha, G. Houdek +6
HD 187547 was the first candidate that led to the suggestion that solar-like oscillations are present in delta Scuti stars. Longer observations, however, show that the modes interp…
