 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

SUMMARY:BHTOM telescope network for LSST time-domain follow-up

DESCRIPTION:Speakers: Lukasz Wyrzykowski (National Centre for Nuclear Rese
 arch/University of Warsaw Astronomical Observatory)\nThe Rubin's LSST will
  transform time-domain astronomy while creating an unprecedented demand fo
 r rapid and sustained follow-up observations. BHTOM.space —the Black Hol
 e Target and Observation Manager—coordinates a global network of nearly 
 200 professional and amateur telescopes and provides automated processing\
 , calibration\, and standardisation of heterogeneous photometric data. Ori
 ginally developed to support Gaia Science Alerts\, BHTOM now covers a broa
 d range of transient and variable phenomena\, including microlensing event
 s\, supernovae\, stellar variability\, quasars\, and Solar System objects.
  In this talk\, I will present the network’s capabilities\, recent scien
 ce applications\, preparations for Rubin/LSST alert-driven observing and t
 he connections to LSST brokers. I will also discuss how BHTOM can connect 
 LSST discoveries with distributed follow-up resources\, turning observatio
 ns from diverse instruments into consistent\, science-ready light curves a
 nd enabling coordinated participation by the Polish and international smal
 l-telescope communities.\n\nhttps://events.ncbj.gov.pl/event/502/contribut

DESCRIPTION:Speakers: Wojciech Szewczuk (University of Wrocław)\nAs LSST 
 will probe faint and distant stellar populations\, it offers an unpreceden
 ted opportunity to study pulsating blue stragglers\, particularly SX Phoen
 icis stars in stellar clusters. Mode identification is a crucial step in a
 steroseismic modelling\, which can provide constraints on the internal str
 ucture and evolutionary history these stars. Photometric method of mode id
 entification exploits the fact that the wavelength dependence of pulsation
  amplitudes and phases varies with the mode geometry. We present various d
 iagnostic diagrams for the models of blue stragglers\nin the LSST passband
 s and assess their potential for mode identification.\n\nhttps://events.nc
