DESCRIPTION:Speakers: Jadwiga Daszyńska-Daszkiewicz (University of Wrocla
 w)\nModelling blue straggler stars (BSSs) is a challenging task because th
 ey undergo non-single-star formation and evolution. Several formation scen
 arios  have been proposed\, but disentangling which pathway is responsible
  for the formation of a given BSS is not straightforward.\n\nTwo steps cou
 ld significantly improve our understanding of these intriguing objects. Fi
 rstly\, we need observables and methods that can place stringent constrain
 ts on the internal structure and evolutionary history of BSSs. \nThis can 
 be achieved by applying asteroseismology to pulsating BSSs (e.g. SX Phoeni
 cis variables)\, by exploiting oscillation modes that carry information ab
 out otherwise inaccessible regions of stars.\nSecondly\, we need to identi
 fy as many pulsating BSSs as possible from observational data across a wid
 e range of stellar clusters. The multi-colour photometry from the Legacy S
 urvey of Space and Time (LSST) has great potential to advance studies of B
 SSs by providing excellent data for extracting pulsation frequencies and i
 dentifying pulsation modes.\n\nHere\, we present our current results from 
 asteroseismic modelling of BSSs and discuss the prospects for identifying 
 BSSs in various stellar clusters from colour–magnitude diagrams using th
 e LSST passbands.\n\nhttps://events.ncbj.gov.pl/event/502/contributions/22
