Hot Stars

The international conference “Hot Stars. Life with Circumstellar Matter” will take place on October 14−19, 2024, in the city of Almaty, Kazakhstan, on campus of the Al-Farabi Kazakh National University. We intend to hold the conference live in a beautiful place located in the foothills of the Tien-Shan mountains that reach heights up to 5000 meters in the vicinity of the city. It is an astronomical site featuring the Fesenkov Astrophysical Institute, Tien-Shan and Assy-Turgen Astronomical Observatories.

The conference will focus on stellar objects at any evolutionary stage that include early-type stars with signs of circumstellar gaseous and dusty material. This definition includes such classes of object as Herbig Ae/Be, classical Be, Vega-type, Wolf-Rayet stars, Proto-Planetary Nebulae, Luminous Blue Variables, other objects with the B[e] phenomenon, and more. Exploration of the evolutionary connections between the mentioned classes leads to better understand the interaction between stellar systems and circumstellar matter and, ultimately, long-term evolution of galaxies. We encourage a broad community of scientists at all stages of their careers to share recent ideas, results, and discoveries and to communicate with each other in a relaxed and friendly atmosphere of a modern and vibrant city.

The Scientific Organizing Committee contains experienced researchers, who help organized conferences focused on topics around hot stars, mass loss, circumstellar material, and stellar evolution. Invited talks will cover such topics as:

Massive stars (theory and modeling)

• Stan Owocki (U. Delaware, USA) “Wind and eruptive Mass-Loss near the Eddington limit”
• Claus Leitherer (Space Telescope Science Inst.) “Integrated Properties of Massive Stellar Populations with the Latest Generation of Atmosphere and Evolution Model
• Richard Ignace (East Tennessee State U., USA) “Spectropolarimetry for Discerning Geometry and Structure in Circumstellar Media.”
• Andreas Sander (U. Heidelberg, Germany) “Studying hot stars and their winds with detailed stellar atmosphere models.”
• Yu-Qing Lou (Tsinghua U., China) “Magnetized Supermassive Stars”

 Binary and Multiple Star systems with gaseous and dusty disks

• Hans Van Winckel (Katholieke U. Leuven, Belgium) “Post-AGB binaries and their dusty discs”
• Anatoly Miroshnichenko (U. North Carolina Greensboro, USA) “Searching for Binaries among Objects with the Be and B[e] Phenomenon”
• Daniela Korčáková (Charles U., Czech Republic) “Intermediate-Mass Mergers: A new scenario for several FS CMa stars”
• Marcelo Borges Fernandes (Obs. Nacional, Brazil) “The B[e] phenomenon and LBVs”
• Alex Lobel (Royal Obs. Belgium) “Multiplicity of Luminous Blue Variable Stars”
