C.; Tarle, Gregory; Thaler, Jon J.; Thomas, Rollin C.; Tucker, Douglas L.; Vikram, Vinu; Wechsler, Risa H.; Weller, Jochen; Wester, William Carl; DES Collaboration (2016) [Artículo de periódico]
      The collapse of a stellar core is expected to produce gravitational waves (GWs), neutrinos, and in most cases a luminous supernova. Sometimes, however, the optical event could be significantly less luminous than a supernova ...

    • Infrared mergers and infrared quasi-stellar objects with galactic winds - II. NGC 5514 : two extranuclear starbursts with LINER properties and a supergiant bubble in the rupture phase 

      Lipari, Sebastian; Mediavilla, Evencio; Garcia-Lorenzo, B.; Díaz, Rubén Joaquín; Acosta-Pulido, J.; Agüero, Maria Paz; Taniguchi, Y.; Dottori, Horacio Alberto; Terlevich, Roberto (2004) [Artículo de periódico]
      A study of the morphology, kinematics and ionization structure of the infrared (IR) merger NGC5514 is presented. This study is based mainly on INTEGRAL two-dimensional (2D) spectroscopy (obtained at the 4.2-m William ...

    • Massive open star clusters using the VVV survey : II. Discovery of six clusters with Wolf-Rayet stars

A.; Kurtev, Radostin Georgiev; Schnurr, Olivier; Bouret, Jean-Claude; Catelan, Márcio; Emerson, Jim P.; Feinstein Baigorri, Carlos; Geisler, Doug; Grijs, Richard de; Hervé, Anthony; Ivanov, Valentin D.; Kumar, M. S. N.; Lucas, Philip W.; Mahy, Laurent; Martins, Fabrice; Mauro, Francesco; Minniti, Dante; Moni Bidin, Christian (2013) [Artículo de periódico]
      Context. The ESO Public Survey “VISTA Variables in the Vía Láctea” (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge, and adjacent regions of the disk. Nearly ...

    • A method for simultaneous determination of A/sub v/ and R and applications 

      Ducati, Jorge Ricardo; Ribeiro, Daiana; Rembold, Sandro Barboza (2003) [Artículo de periódico]
      A method for the simultaneous determination of the interstellar extinction (AV) and of the ratio of total to selective extinction (R), derived from the 1989 Cardelli, Clayton, & Mathis fitting of the interstellar extinction ...

    • New evolutionary sequences for hot h-deficient white dwarfs on the basis of a full account of progenitor evolution 

      Althaus, Leandro Gabriel; Panei, Jorge Alejandro; Bertolami, Marcelo Miguel Miller; García-Berro, Enrique; Córsico, Alejandro Hugo; Romero, Alejandra Daniela; Kepler, Souza Oliveira; Rohrmann, R. D. (2009) [Artículo de periódico]
      We present full evolutionary calculations appropriate for the study of hot hydrogen-deficient DO white dwarfs, PG 1159 stars, and DB white dwarfs. White dwarf sequences are computed for a wide range of stellar masses and ...

    • A new luminous blue variable : R143 in 30 Doradus 

      Parker, Joel Wm.; Clayton, Geoffrey C.; Winge, Claudia; Conti, Peter S. (1993) [Artículo de periódico]
      We have discovered that R143 in the Large Magellanic Cloud is a luminous blue variable (LBV), the first and perhaps the lone LBV in the central cluster of 30 Doradus, and only the sixth known LMC LBV. Photo­ metric and ...

    • On the possible existence of short-period g-mode instabilities powered by nuclear-burning shells in post-asymptotic giant branch h-deficient (PG1159-TYPE) stars 

      Córsico, Alejandro Hugo; Althaus, Leandro Gabriel; Bertolami, Marcelo Miguel Miller; Gonzalez Perez, Jose Miguel; Kepler, Souza Oliveira (2009) [Artículo de periódico]
      We present a pulsational stability analysis of hot post-asymptotic giant branch (AGB) H-deficient pre-white dwarf stars with active He-burning shells. The stellar models employed are state-of-the-art equilibrium structures ...

    • The very reddened open clusters Pismis 23 (Lynga 10) and Stephenson 2 

      Ortolani, Sergio; Bica, Eduardo Luiz Damiani; Barbuy, Beatriz; Momany, Yazan (2002) [Artículo de periódico]
      Pismis 23 and Stephenson 2 are two very reddened open clusters, projected close to the Galactic plane. We present VI and JH photometry for Pismis 23 and I and Gunn z for Stephenson 2. We derive a relatively old age of ~ ...
