Since a star’s mass determines how hot it burns (as well as how strong its gravity pull is), the star’s classification actually helps extrapolate the kinds of planets that might be in that star’s system.

... V37. The period 0.237 d, listed in Clement (2002), does not produce a smooth light curve but a rather dispersed cloud of points. Although our estimate of a 0.28775 d period phases the observations reasonably well, the light curve is noisy (see Fig. 5) due to the proximity of the star to the central ...
