Welcome to the
9th Meeting on Hot Subdwarfs and Related Objects

This meeting is the 9th edition of a series of biennal conferences started in 2003. These conferences provide experts from around the world the opportunity to regularly discuss results and thoughts relative to hot subdwarf stars and other related objects. The main topics discussed are

  • Progenitors, progenies, origin and evolution of hot subdwarf stars : standard and alternative pathways
  • Hot subdwarfs in the field, clusters, and galaxies
  • Impact of large surveys and hot subdwarf population studies
  • Atmospheric properties of hot subdwarf stars
  • Hot subdwarfs in binary systems
  • Pulsating hot subdwarfs and asteroseismology
  • Hot subdwarfs as laboratories for stellar physics : convection, diffusion, atomic data, tides, mergers, common envelopes
  • Links to extremely low mass white dwarfs and other related objects

The conference is organised by the Institut de Recherche en Astrophysique et Planétologie (IRAP) and will take place from June 23 – 28 at Azureva Hendaye, near Biarritz, France.
