The star Alphard (otherwise known as Alpha Hydrae or Cor Hydrae) is a yellow-orange spectral type K3 star that has evolved away from the main sequence onto the giant branch as its core hydrogen fuel supply has become depleted.
Description (Specifications)
- The spectrum of Alphard revelas an excess of barium, which is an element that is normally produced by the s-process of nucleosynthesis. Typically stars with such barium excesses belong to binary systems and the associated anomalies in barium abundances are explained by mass transfer from a companion white dwarf star.
- The Alphard star system lies approximately 55.3pc from Terra, and is located in a Rimward/Rimtrailing direction from Terra at bearing 241.5o Galactic Longitude and +29.0o North Galactic Latitude.
