    • An Hα nuclear spiral structure in the E0 active galaxy Arp 102B 

      Fathi, Kambiz; Axon, David J.; Storchi-Bergmann, Thaisa; Kharb, Preeti; Robinson, Andrew; Marconi, A.; Maciejewski, Witold B.; Capetti, A. (2011) [Journal article]
      We report the discovery of a two-armed mini-spiral structure within the inner kiloparsec of the E0 LINER/Seyfert 1 galaxy Arp 102B. The arms are observed in Hα emission and located east and west of the nucleus, extending ...

    • Discovery of two embedded clusters with WISE in the high Galactic latitude cloud HRK 81.4−77.8 

      Camargo, Denilso da Silva; Bica, Eduardo Luiz Damiani; Bonatto, Charles Jose; Salerno, Gustavo Malta (2015) [Journal article]
      Molecular clouds at very high latitude (b > 60°) away from the Galactic plane are rare and in general are expected to be non-star-forming. However, we report the discovery of two embedded clusters (Camargo 438 and Camargo ...

    • Molecular chemistry and the missing mass problem in planetary nebulae 

      Kimura, Rafael Kobata; Gruenwald, Ruth B.; Aleman, Isabel Regina Guerra (2012) [Journal article]
      Context. Detections of molecular lines, mainly from H₂ and CO, reveal molecular material in planetary nebulae. Observations of a variety of molecules suggest that the molecular composition in these objects differs from ...

    • Temperature inversion in long-range interacting systems 

      Teles, Tarcisio Nunes; Gupta, Shamik; Di Cintio, Pierfrancesco; Casetti, Lapo (2015) [Journal article]
      Temperature inversions occur in nature, e.g., in the solar corona and in interstellar molecular clouds: Somewhat counterintuitively, denser parts of the system are colder than dilute ones.We propose a simple and appealing ...

    • The fate of the pre-main sequence-rich clusters collinder 197 and vdB92 : dissolution? 

      Bonatto, Charles Jose; Bica, Eduardo Luiz Damiani (2010) [Journal article]
      Context. Since most of the star clusters do not survive the embedded phase, their early dissolution appears to be a major source of field stars. However, catching a cluster in the act of dissolving is somewhat elusive. ...
