GlobULeS-V. UVIT/<i>AstroSat</i> studies of stellar populations in NGC 362: Detection of blue lurkers in a globular cluster

We report the discovery of four blue lurkers with low and extremely low-mass white dwarf (ELM WDs) companions in Galactic globular cluster NGC 362 using AstroSat Ultra Violet Imaging Telescope (UVIT). analyzed multi-wavelength spectral energy distribution (SED) FUV-bright MS stars data from UVIT, UVOT, GAIA EDR3, 2.2m ESO/MPI telescopes. Two each WDs ELM are found as for by fitting two-component SED models. The effective temperatures, radii, luminosities, masses two (35000, 23000) K, (0.04, 0.05) Rsun , (1.45, 0.22) Lsun (0.2, 0.2) Msun, while (14750, 14750) (0.09, 0.10) Rsun, (0.34, 0.40) Lsun, (0.18, 0.18) Msun. position within shows that they originated via Case A/B mass-transfer mechanism a low-density environment. This is first detection cluster. companion cooling age less than 4 Myr, which suggests were just recently formed. These binary systems might have due to recent core collapse.
