(spectral class of star a bit hotter than then Sun)
An F-type star is a star within the F-class, a
spectral class indicating stars with neutral hydrogenlines
a yellow-white color,
and a surface temperature in the range of 6200-7200 K,
a bit hotter than the Sun,
with a spectral energy distribution (SED) peaking within the visible range.
Main sequence stars of this class are on the order of
1.5 solar masses, 1.5 times solar radius, and a bit brighter than the Sun.
Such main sequence stars burn their hydrogen in a few billion years.
Characteristics of F-type main sequence stars:
F-type main sequence stars are somewhat Sun-like and
a number are within 10 parsecs, making them
of interest in checking for extra-solar planets
