DESCRIPTION:Speakers: INDU KALPA DIHINGIA (Ningbo University)\nJWST's litt
 le red dots (LRDs) are unexpectedly non-variable. We present a semi-analyt
 ic framework for variability in super-Eddington slim disks with winds\, co
 mbining photon trapping\, photospheric averaging\, and diffusion filtering
 \, calibrated on ordinary quasars. Forward-modeling the TWINKLE non-detect
 ions of 18 LRDs\, we derive a lower limit ṁ ≳ 60 (95% confidence) for 
 10⁷ M⊙ black holes\, excluding sub-Eddington interpretations\, and pre
 dict mass-segregated variability and suppressed X-ray variability that are
  testable with future observatories.\n\nhttps://indico.itp.ac.cn/event/417
