    • A six planet system around the Star HD 34445 
      Vogt, Steven S.; Butler, R. Paul; Burt, Jennifer; Tuomi, Mikko; Laughlin, Gregory; Holden, Brad; Teske, Johanna K.; Shectman, Stephen A.; Crane, Jeffrey D.; Díaz, Matias; Thompson, Ian B.; Arriagada, Pamela; Keiser, Sandy (IOP Publishing Ltd., 2017)
      We present a new precision radial velocity (RV) data set that reveals a multi-planet system orbiting the G0V star HD 34445. Our 18-year span consists of 333 precision RV observations, 56 of which were previously published ...
    • A Flexible, Lightweight Middleware Supporting the Development of Distributed Applications across Platforms 
      Baloian Tataryan, Nelson; Zurita Alarcón, Gustavo; Antunez, Pedro; Baytelman Pilowsky, Felipe Bruno (2007)
      Middleware supporting the development of distributed systems has been produced since the beginnings of the Internet. With the emergence of mobile computing new requirements for this kind of middleware arise since the ...
    • Investigating Cepheid l Carinae' s cycle-to-cycle variations via contemporaneous velocimetry and ... 
      Anderson, R. I.; Mérand, A.; Kervella, Pierre; Breitfelder, J.; Le Bouquin, J. B.; Eyer, L.; Gallenne, A.; Palaversa, L.; Semaan, T.; Saesen, S.; Mowlavi, N. (Oxford University Press, 2016)
      Baade-Wesselink-type (BW) techniques enable geometric distance measurements of Cepheid variable stars in the Galaxy and the Magellanic clouds. The leading uncertainties involved concern projection factors required to ...
    • The lick-carnegie exoplanet survey: hd 32963-a new jupiter analog orbiting asun-like star 
      Rowan, Dominick; Meschiar, Stefano; Laughlin, Gregory; Vogt, Steven S.; Butler, R. Paul; Burt, Jennifer; Wang, Songhu; Holden, Brad; Hanson, Russell; Arriagada, Pamela; Keiser, Sandy; Teske, Johanna; Díaz, Matias (IOP PUBLISHING LTD, 2016)
      We present a set of 109 new, high-precision Keck/HIRES radial velocity (RV) observations for the solar-type star HD 32963. Our data set reveals a candidate planetary signal with a period of 6.49 +/- 0.07 years and a ...
    • A Platform for Motivating Collaborative Learning Using Participatory Simulation Applications 
      Zurita Alarcón, Gustavo; Baloian Tataryan, Nelson; Baytelman Pilowsky, Felipe Bruno; Farías Landabur, Antonio (2007)
      Several research efforts suggest that collaborative participatory simulations improve teaching and learning, increasing motivation inside the classroom. Currently, it has been mainly applied with students of primary and ...
    • Radiation damage effects in space-borne CCD detectors operated in TDI mode 
      Terrazas Vargas, Juan; Corcione, L.; Lattanzi, M.G.; Gai, M. (IOP Publishing, 2017-07-01)
      We evaluate the astrometric and photometric implications of a series of laboratory tests conducted to study the effects of radiation damage caused by solar protons in space-borne charge coupled devices (CCDs). The photometric ...
    • Resolving asymmetries along the pulsation cycle of the Mira star X Hydrae 
      Haubois, X.; Wittkowski, M.; Perrin, G.; Kervella, Pierre; Mérand, A.; Thiébaut, E.; Ridgway, S.; Ireland, M.; Scholz, M. (EDP Sciences, 2015)
      Context. The mass-loss process in Mira stars probably occurs in an asymmetric way where dust can form in inhomogeneous circumstellar molecular clumps. Following asymmetries along the pulsation cycle can give us clues about ...
    • Shadowing and multiple rings in the protoplanetary disk of HD 139614 
      Muro Arena, G. A.; Benisty, Myriam; Ginski, C.; Dominik, C.; Facchini, S.; Villenave, M.; van Boekel, R.; Chauvin, G.; Garufi, A.; Henning, T.; Janson, M.; Keppler, M.; Matter, A.; Menard, F.; Stolker, T.; Zurlo, A.; Blanchard, P.; Maurel, D.; Moeller Nilsson, O.; Petit, C.; Roux, A.; Sevin, A.; Wildi, F. (EDP Sciences, 2020)
      Context. Shadows in scattered light images of protoplanetary disks are a common feature and support the presence of warps or misalignments between disk regions. These warps are possibly caused by an inclined (sub-)stellar ...
    • Shallow transit follow-up from next-generation transit survey: simultaneous observations of HD 106315 with ... 
      Smith, Alexis; Eigmüller, Philipp; Gurumoorthy, Ramanathan; Csizmadia, Szilárd; Bayliss, Daniel; Burleigh, Matthew R.; Cabrera, Juan; Casewell, Sarah; Erikson, Anders; Goad, Michael; Grange, Andrew; Jenkins, James Stewart; Pollacco, Don; Rauer, Heike; Raynard, Liam; Udry, Stéphane; West, Richard; Wheatley, Peter (Wiley, 2020)
      The Next Generation Transit Survey (NGTS) is a photometric survey for transiting exoplanets, consisting of 12 identical 0.2-m telescopes. We report a measurement of the transit of HD 106315 c using a novel observing mode ...
    • Supporting the Development of Applications in Heterogeneous Ubiquitous Computing Environments 
      Baloian Tataryan, Nelson; Zurita Alarcón, Gustavo (Springer-Verlag, 2008)
      Ubiquitous computing is increasingly becoming part of our lives. Various computing devices, having different sizes and capabilities, and using different software platforms are part of our working, leisure and living ...
    • The VLTI/PIONIER near-infrared interferometric survey of southern T Tauri stars
