VizieR Online Data Catalog: Pan-Pacific Planet Search (PPPS) I. 7 CMa (Wittenmyer+, 2011)
Abstract
The "Pan-Pacific Planet Search" (PPPS) originated as a Southern Hemisphere extension of the established Lick & Keck Observatory survey for planets orbiting Northern "retired A stars" (Johnson et al. 2006ApJ...652.1724J, 2007ApJ...665..785J, 2010PASP..122..905J). This program is using the 3.9m Anglo-Australian Telescope (AAT) to observe a metal-rich sample of Southern Hemisphere subgiants. Observations for the PPPS began at the AAT in 2009 February. Observing time is scheduled such that each target should receive 4-6 observations per year. PPPS Doppler measurements are made with the UCLES echelle spectrograph (at the 3.9m AAT) which achieves a resolution of 45000 with a 1 arcsec slit.
We have observed 7 CMa on 21 epochs, and an iodine-free template observation was obtained on 2010 January 30. Since 7 CMa is an extremely bright star, exposure times ranged from 100 to 500s, with a resulting S/N of ~200-300/pixel each epoch. The data span a total of 917 days and have a mean internal velocity uncertainty of 6.5m/s. (2 data files).- Publication:
