    • The 2022–2023 accretion outburst of the young star V1741 Sgr 

      Kuhn, Michael; Hillenbrand, Lynnee A.; Connelley, Michael S.; Rich, R. Michael; Staels, Bart; Carvalho, Adolfo S.; Lucas, Philip; Fremling, Christoffer; Karambelkar, Viraj R.; Lee, Ellen; Ahumada, Tomás; Ishida, Emille E.~O.; De, Kishalay; de Souza, Rafael S.; Kasliwal, Mansi M. (2024-04-01)
      V1741 Sgr (= SPICY 71482/Gaia22dtk) is a Classical T Tauri star on the outskirts of the Lagoon Nebula. After at least a decade of stability, in mid-2022, the optical source brightened by ∼3 mag over 2 months, remained ...

    • A graph-based spectral classification of Type II supernovae 

      de Souza, Rafael S.; Thorp, Stephen; Galbany, Lluis; Ishida, Emille E.~O.; González-Gaitán, Santiago; Schmitz, Morgan A.; Krone-Martins, Alberto; Peters, Christina (2023-06-06)
      Given the ever-increasing number of time-domain astronomical surveys, employing robust, interpretative, and automated data-driven classification schemes is pivotal. Based on graph theory, we present new data-driven ...

    • 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 ...
