Abstract:
We present new BVI photometry containing 40,000 stars of the Galactic
globular cluster M15 (NGC 7078), covering a 25'x25' area
centered on the cluster with a magnitude range from the tip of the red
giant branch to 3 mag below the main sequence turnoff. Using
α-enhanced Dartmouth Stellar Evolution Program models, we find
an age of 13.0±1.0Gyr and distance modulus of (m-M)V=15.4±0.1
through isochrone fitting. Unlike previous works, we find good
agreement between the observed completeness-corrected stellar
luminosity function and models.
Description:
M15 was observed during three observing runs in 2002 November, 2003
September, and 2004 September using the Hiltner 2.4m telescope at the
MDM Observatory at Kitt Peak, AZ. All frames were taken using the
Echelle camera, a 2048x2048 pixel camera with a field of view of
approximately 9'x9'.
