Astrophysical: Exoplanet dynamics

  • Publication
    Asteroseismology of iota Draconis and Discovery of an Additional Long-period Companion
    Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted...
