      We present the Coordinated Synoptic Investigation of NGC 2264, a continuous 30-day multi-wavelength photometric monitoring campaign on more than 1000 young cluster members using 16 telescopes. The unprecedented combination ...

    • Gaia21bty: An EXor light curve exhibiting a FUor spectrum 

      Siwak, Michał; Hillenbrand, Lynne A.; Kóspál, Ágnes; Ábrahám, Péter; Giannini, Teresa; De, Kishalay; Moór, Attila; Szilágyi, Máté; Janík, Jan; Koen, Chris; Park, Sunkyung; Nagy, Zsófia; Miera, Fernando Cruz-Sáenz de; Fiorellino, Eleonora; Marton, Gábor; Kun, Mária; Lucas, Philip W.; Udalski, Andrzej; Szabó, Zsófia Marianna (2023-10-30)
      Gaia21bty, a pre-main sequence star that previously had shown aperiodic dips in its light curve, underwent a considerable Delta G~2.9 mag brightening that occurred over a few months between 2020 October - 2021 February. ...

      Most protostars have luminosities that are fainter than expected from steady accretion over the protostellar lifetime. The solution to this problem may lie in episodic mass accretion -- prolonged periods of very low accretion ...

    • LkH$α$ 225 (V1318 Cyg) South in Outburst 

      Hillenbrand, Lynne A.; Isaacson, Howard; Rodriguez, Antonio C.; Connelley, Michael; Reipurth, Bo; Kuhn, Michael A.; Beck, Tracy; Perez, Diego Rodriguez (2022-03-31)
      Magakian et al. called attention to the current bright state of LkHα 225 South, a well-known highly embedded,intermediate-mass young stellar object that over the past two decades has brightened visually from >20m to <13m.We ...

    • Spectroscopic Confirmation of a Population of Isolated, Intermediate-mass Young Stellar Objects 

      Kuhn, Michael A.; Saber, Ramzi; Povich, Matthew S.; de Souza, Rafael S.; Krone-Martins, Alberto; Ishida, Emille E.~O.; Zucker, Catherine; Benjamin, Robert A.; Hillenbrand, Lynne A.; Castro-Ginard, Alfred; Zhou, Xingyu; Collaboration, COIN (2023-01-31)
      Wide-field searches for young stellar objects (YSOs) can place useful constraints on the prevalence of clustered versus distributed star formation. The Spitzer/IRAC Candidate YSO (SPICY) catalog is one of the largest ...

      Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of the mass accretion rate onto TW Hya, ...
