名词 n.
  1. A star that is dimmer than a main-sequence star of same temperature; located below the main sequence on the Hertzsprung-Russell diagram.
    — Data from the Keck Observatory’s Near-Infrared Echellette Spectrograph suggested the star was an L subdwarf, or a star with a much lower mass and cooler temperature than the sun. Cool subdwarfs are the oldest stars in the galaxy. […] Kremer carried out simulations and discovered that three-body interactions can knock a low-mass subdwarf star from a cluster and put it on a trajectory that is similar to that of J1249+36.
