    Three contributions to the \"A Half Century of Stellar Pulsation Interpretations\" proceedings
    (1997) Catelan, Marcio; Sweigart, A. V.; Borissova, J.; Spassova, N.; Ivanov, V. D.
    Paper I: "RR Lyrae Variables in Globular Clusters and the Second-Parameter Phenomenon" Authors: M. Catelan, A. V. Sweigart, J. Borissova Abstract: We propose to use RR Lyrae variables in globular clusters to probe the origin of the second-parameter phenomenon. Paper II: "New Possible Variables in the Outer-Halo Globular Cluster Palomar 3" Authors: J. Borissova, N. Spassova, M. Catelan, V. D. Ivanov Abstract: We present a list of ten possible variable stars in the globular cluster Pal 3. Seven are new suspected variables. The variability of the RR Lyr candidate reported by Burbidge & Sandage (1958), as well as of the Pop. II Cepheid and RR Lyr from Gratton & Ortolani (1984), are confirmed. Paper III: "On the Production of Bright RR Lyrae Variables in Metal-Rich Globular Clusters" Authors: A. V. Sweigart, M. Catelan Abstract: See astro-ph/9708174....

    Variable Stars in Metal-Rich Globular Clusters: NGC 6304 and NGC 6569
    (2002) Pritzl, Barton J.; Smith, Horace A.; Catelan, Marcio; Sweigart, Allen V.
    It has recently become evident that the RR Lyrae in metal-rich globular clusters ([Fe/H]> -1.0) have properties different from those of metal-rich RR Lyrae found in the field. In particular, they have longer periods than field RR Lyrae of similar metallicities, implying that the cluster RR Lyrae are more luminous than their field counterparts. Because RR Lyrae stars are major Population II standard candles, this finding has consequences for the ages of globular clusters and the galactic and extragalactic distance scales. We propose observations with the YALO telescope to obtain B,V CCD photometry of the RR Lyrae in the metal-rich globular clusters NGC 6304 and NGC 6569. These data will be used to obtain accurate periods and light curves for the RR Lyrae and will be compared to those in other systems to determine their relative luminosities. Direct comparisons will also be made to the other metal-rich globular clusters known to contain RR Lyrae.

    Toma de decisiones políticas y la influencia de los discursos oficialistas durante el conflicto del Beagle: Chile-Argentina 1977-1979
    (Pontificia Universidad Católica de Chile, Instituto de Ciencia Política, 2006) Delgado Muñoz, Gustavo Andrés; Mariángel Carvajal, Karen J.
    Esta investigación tiene por objetivo describir y explicitar cómo se desarrolló el conflicto por las islas australes del Canal Beagle (Picton, Nueva y Lennox) en su período más álgido (entre 1977 y 1979), analizando las características de la crisis y el proceso de toma de decisiones políticas [PTDP] existente en las Juntas Militares de gobierno de ambos países, y de sus actores más destacados, todos los cuales, a través de un análisis racional de sus acciones, (privilegiando la que le entregara mayores beneficios en función de un daño menor) buscarán encontrar una solución adecuada a sus intereses para este diferendo. Asimismo, se pretende a través de este estudio, identificar el grado de incidencia que los discursos de cada mandatario y actores principales tuvieron en el conflicto diplomático, determinando si los grados de coerción, encubrimiento, legitimación y deslegitimación presentes en los discursos del período se corresponden con el carácter de los cursos de acción diplomática. En este sentido, se afirma que los discursos constituyen un reflejo de las intenciones de ambas partes al tiempo que determinan la percepción que de ellas se tienen. De esta forma, se apreciará cómo las declaraciones analizadas presentan marcadamente una defensa y un uso de argumentos jurídicos, por parte de Chile, mientras que Argentina manifestará un mayor número de aparición de elementos relacionados con argumentos afectivos y racionales, así como un predominio de la deslegitimación hacia el laudo y hacia la decisión chilena de respetarlo.

    The pre-Nova Lightcurve of KT Eri (Nova Eridani 2009)
    (2009) Drake, A. J.; Djorgovski, S. G.; Graham, M. J.; Mahabal, A. A.; Williams, R.; Wils, P.; Greaves, J.; Catelan, Marcio; Prieto, J.; Beshore, E. C.; Larson, S. M.; Boattini, A.; Gibbs, A.; Grauer, A.; Hill, R.; Kowalski, R.; Christensen, E.
    Here we report on historical observations of the pre-Nova source of KT Eri (Nova Eridani 2009). Following the detection of the possible Nova at mag 8.1 by Yamaoka et al. (2009, CBET#2050), we carried out a search of Catalina Sky Survey 0.7m data covering the location of this event. Photometry of the source was found with dates between 2005-01-17 and 2009-11-18 UT. The Nova was clearly seen in outburst in images taken on Nov.

    Supernova 2010hj in Pgc 67413
    (2010) Drake, A. J.; Djorgovski, S. G.; Mahabal, A.; Graham, M. J.; Williams, R.; McNaught, R. H.; Garradd, G.; Howerton, S.; Prieto, J. L.; Catelan , Marcio; Beshore, E. C.; Larson, S. M.; Christensen, E.
    Report the discovery of an apparent supernova in unfiltered Siding Spring Survey (SSS) images: SN 2010 UT R.A. (2000.0) Decl. Mag. Offset 2010hj Aug. 4.61 21 49 09.84 -59 02 23.2 17.1 5".5 W, 8".2 S Nothing was visible at this position on an SSS image from 2009 Oct. 1.50 UT (limitiing mag 18.9), but 2010hj was detected again in SSS images on Aug. 29.59 (no magnitude provided). The host galaxy appears to be PGC 67413 = ESO 145-G16. Joseph Brimacombe, Cairns, Australia, reports that ten stacked 600-s CCD images (limiting magnitude 20) taken remotely with a 32-cm RCOS telescope (+ STL6K camera + clear filter) at the Macedon Ranges Observatory near Melbourne, Australia, on Aug. 29.727 show the new object to be at mag 18.3 and located approximately 7" west and 7" south of the presumed host-galaxy nucleus. Another stacked image (seven 1200-s frames; limiting magnitude 20), taken by Brimacombe on Sept. 2.636 with a 40-cm RCOS telescope (+ U16 camera + red filter) at the Coral Towers Observatory (Cairns), yields mag 18.6 for 2010hj; the Sept. 2 stacked image has been posted at the following website URL: http://www.flickr.com/photos/43846774@N02/4952444311/....
