A Bcool magnetic snapshot survey of solar-type stars
S. C. Marsden, P. Petit, S. V. Jeffers +20
Stellar magnetic field measurements obtained from spectropolarimetry offer key data for activity and dynamo studies, and we present the results of a major high-resolution spectropo…
Starspots on Young Solar-Type Stars
Carolyn Brown, Brad Carter, Stephen Marsden +1
Doppler Imaging of starspots on young solar analogues is a way to investigate the early history of solar magnetic activity by proxy. Doppler images of young G-dwarfs have yielded t…
A Bcool spectropolarimetric survey of over 150 solar-type stars
Stephen Marsden, Pascal Petit, Sandra Jeffers +3
As part of the Bcool project, over 150 solar-type stars chosen mainly from planet search databases have been observed between 2006 and 2013 using the NARVAL and ESPaDOnS spectropol…
Forever alone? Testing single eccentric planetary systems for multiple companions
Robert A. Wittenmyer, Songhu Wang, Jonathan Horner +9
Determining the orbital eccentricity of an extrasolar planet is critically important for understanding the system's dynamical environment and history. However, eccentricity is ofte…
