DESCRIPTION:Speakers: Seokhoon Yun (Department of Physics\, Kyungpook Nati
 onal University (KNU))\n\nAbstract:Dark matters can be captured and keep l
 osing energy\, leading to ingress into a stellar medium. Such captured dar
 k matters can form a black hole if the thermalized dark matter density exc
 eeds the stellar core density. The fate of such a tiny mass black hole rel
 ies on its initial mass. During evolution\, the mini black hole generates 
 an energy injection into the surrounding medium. I will discuss possible e
 ffect of this heat-up effect on red-giant medium\, which can induce a prem
 ature helium flash\, leading to a stringent constraint.Bio:Prof. Seokhoon 
 Yun is an Assistant Professor in the Department of Physics at Kyungpook Na
 tional University\, Republic of Korea. He received his Ph.D. from KAIST in
  2018 and\, before joining KNU in 2026\, held research positions at KIAS\,
  the University of Padova\, and the IBS Center for Theoretical Physics of 
 the Universe. He is a particle phenomenologist whose research focuses on p
 hysics beyond the Standard Model\, with an emphasis on particle cosmology 
 and astroparticle physics.\nAlternative online link: https://meeting.tence
