I'm seeing conflicting sources. Some call it Helios, and others call it Delta-Pavonis. I'm also curious if we know what position from the sun Dawn is located at.
Delta Pavonis is the name of the sun and the system used before the human colonization, Helios is the name of both sun and system used by the Ariadnan society. Dawn is the 4th planet from its sun. Source : Infinity the role game, https://en.m.wikipedia.org/wiki/Delta_Pavonis Cheers
Delta Pavonis is also the star around which another famous SF planet orbits. The Planet Caladan, from Frank Herbert's Dune novels.
Look at this , so cool ... https://en.m.wikipedia.org/wiki/Stars_and_planetary_systems_in_fiction#Delta_Pavonis
