61 Virginis is a yellow - orange
main sequence dwarf
of spectral and luminosity
type G5 - 6 V, with about 92 to 96 percent
of Sol's mass (95 percent using the isochrone mass estimate
of Valenti and Fischer, 2005; and NASA Star and Exoplanet Database, based on David F. Gray, 1992), 94 to 98 percent
of its diameter (96 percent for Valenti and Fischer, 2005; Johnson and Wright, 1983, page 677; and NASA Star and Exoplanet Database, derived from the exponential
formula of Kenneth R. Lang, 1980), and around 78 percent
of its visual luminosity and nearly 81 percent
of its theoretical bolometric luminosity, with infrared radiation (Sousa et al, 2008; Valenti and Fischer, 2005; NASA Star and Exoplanet Database, based on Kenneth R. Lang, 1980).
That basic
formula makes cash back credit cards the easiest to understand
of the three
main types of rewards credit cards, and the
type that delivers the most flexible
of perks — since nothing is more universal than cash.
While we didn't want to eliminate every single
formula that had any
type of meal anywhere (this would've left only a small number
of extremely pricey
formulas), we did feel that a truly high - quality dog food shouldn't take shortcuts on its
main ingredient.
