    Even more-massive stars are born directly onto the Henyey track. The end (leftmost point) of every track is labeled with the star's mass in solar masses (M ☉), and represents its position on the main sequence. The red curves labeled in years are isochrones at the given ages.

    An accurate determination of the distance to the Galactic Center as established from variable stars (e.g. RR Lyrae variables) or standard candles (e.g. red-clump stars) is hindered by numerous effects, which include: an ambiguous reddening law; a bias for smaller values of the distance to the Galactic Center because of a preferential sampling ...
