A multi-site campaign to measure solar-like oscillations in Procyon. I. Observations, Data Reduction and Slow Variations (2008)

Arentoft, Torben, Kjeldsen, Hans, Bedding, Timothy R., Bazot, Michael, Christensen-Dalsgaard, Joergen, Dall, Thomas H., ...

We have carried out a multi-site campaign to measure oscillations in the F5 star Procyon A. We obtained high-precision velocity observations over more than three weeks with eleven telescopes, with...

On the Nature of the Radial Velocity Variability of Aldebaran: A Search for Spectral Line Bisector Variations (2007)

Artie Hatzes, William D. Cochran

The shape of the Ti I 6303.8 A spectral line of Aldebaran as measured by the line bisector was investigated using high signal-to-noise, high resolution data. The goal of this study was to understand...

NACO-SDI direct imaging search for the exoplanet Eps Eri b (2007)

Janson, Markus, Brandner, Wolfgang, Henning, Thomas, Lenzen, Rainer, McArthur, Barbara, Benedict, G. Fritz, ...

The active K2V star $\epsilon$ Eri hosts the most nearby known extrasolar planet. With an angular separation of about 1" on average, and an age of a few to several hundred Myrs, $\epsilon$ Eri b is...

NACO-SDI direct imaging search for the exoplanet e Eri b (2007)

Janson, Markus, Brandner, Wolfgang, Henning, Thomas, Lenzen, Rainer, McArthur, Barbara, Benedict, G. Fritz, ...

The active K2 V star ɛ Eri hosts the nearest known extrasolar planet. With an angular separation of about 1" on average, and an age of a few to several hundred megayears, ɛ Eri b is one of the...

Interplay between diffusion, accretion and nuclear reactions in the atmospheres of Sirius and Przybylski's star (2006)

Yushchenko, Alexander, Gopka, Vera, Goriely, Stephane, Shavrina, Angelina, Kang, Young Woon, Rostopchin, Sergey, ...

The abundance anomalies in chemically peculiar B-F stars are usually explained by diffusion of chemical elements in the stable atmospheres of these stars. But it is well known that Cp stars with...

The Extrasolar Planet epsilon Eridani b - Orbit and Mass (2006)

Benedict, G. Fritz, McArthur, Barbara E., Gatewood, George, Nelan, Edmund, Cochran, William D., Hatzes, Artie, ...

Hubble Space Telescope observations of the nearby (3.22 pc), K2 V star epsilon Eridani have been combined with ground-based astrometric and radial velocity data to determine the mass of its known...
