| Abstract: |
For many decades the determination of accurate fundamental parameters
for stars (masses, radii, temperatures, luminosities, etc.) has mostly
been the domain of eclipsing binary systems. That has begun to change
as long-baseline interferometric techniques have improved
significantly, and powerful new instruments have come online. This
paper will review the status of the field, and in particular how the
knowledge of precise stellar properties helps us understand stars.
Main-sequence stars similar to the Sun are by far the best studied,
but much remains to be done for other kinds of objects such as
early-type as well as late-type stars including brown dwarfs, evolved
stars, metal-poor stars, and pre-main-sequence stars. Progress is
illustrated with several examples of how interferometry has
contributed significantly in some of these areas. |
