INT survey of local dwarf gal. VIII. LPV stars
Listed in IVOA Registry (Virtual Observatory)
We present a comprehensive catalog, in the Sloan i and Harris V filters, of long-period variable (LPV) stars in the spheroidal dwarf satellites of the Andromeda galaxy based on a dedicated survey for variable stars in Local Group dwarf systems.
Description
Using photometric time-series data obtained with the Wide Field Camera on the 2.5m Isaac Newton Telescope, we identify approximately 2800 LPV candidates across 17 Andromeda satellites, spanning a broad range in luminosity and variability amplitude.
This study is accompanied by a public data release that includes two comprehensive catalogs, a catalog of the complete stellar populations for each galaxy, and a separate catalog listing all identified LPV candidates. Both are available through CDS/VizieR and provide a valuable resource for investigating quenching timescales, stellar mass distributions, and the effects of mass loss and dust production in dwarf galaxies.

We derive updated structural parameters, including newly measured half-light radii, and determine distance moduli using the tip of the red giant branch method with Sobel filter edge detection, yielding values between 23.38{\pm}0.06 and 25.35{\pm}0.06mag.
