Trends in Space Astronomy and Cosmic Vision 2015-2025
Catherine Turon, Chris Done, Andreas Quirrenbach +14
As a short introduction to the astronomy session, the response of the community to the Call for Themes issued by ESA and the specific themes selected by the Astronomy Working Group…
Radial Velocity Variations in K Giants: Planets or Pulsations?
Saskia Hekker, Sabine Reffert, Andreas Quirrenbach
Radial velocity observations of K giants have revealed periodic variations for some of the stars. The periods range from approximately 180 to 1000 or more days with velocity amplit…
Report by the ESA-ESO Working Group on Extra-Solar Planets
M. Perryman, O. Hainaut, D. Dravins +14
Various techniques are being used to search for extra-solar planetary signatures, including accurate measurement of radial velocity and positional (astrometric) displacements, grav…
A dearth of planetary transits in the direction of NGC 6940
Ben Hood, Andrew Collier Cameron, Stephen R. Kane +10
We present results of our survey for planetary transits in the field of NGC 6940. We think nearly all of our observed stars are field stars. We have obtained high precision (3-10 m…
A Survey for Planetary Transits in the Field of NGC 7789
D. M. Bramich, Keith Horne, I. A. Bond +12
We present results from 30 nights of observations of the open cluster NGC 7789 with the WFC camera on the INT telescope in La Palma. From ~900 epochs, we obtained lightcurves and S…
