THE AGE AND STELLAR PARAMETERS OF THE PROCYON BINARY SYSTEM
@article{Liebert2013THEAA, title={THE AGE AND STELLAR PARAMETERS OF THE PROCYON BINARY SYSTEM}, author={James William Liebert and Gilles Fontaine and Patrick A. Young and Kurtis A. Williams and David C. Arnett}, journal={The Astrophysical Journal}, year={2013}, volume={769}, pages={7} }
The Procyon AB binary system (orbital period 40.838 yr, a newly refined determination) is near and bright enough that the component radii, effective temperatures, and luminosities are very well determined, although more than one possible solution to the masses has limited the claimed accuracy. Preliminary mass determinations for each component are available from Hubble Space Telescope imaging, supported by ground-based astrometry and an excellent Hipparcos parallax; we use these for our…
