    • Asteroids in the high cadence transient survey 

      Peña, J.; Fuentes González, César; Forster, Francisco; Maureira, Juan Carlos; San Martín, J.; Littin, J.; Huijse Heise, Pablo Andrés; Cabrera Vives, Guillermo; Estévez Valencia, Pablo; Galbany, Lluis; González Gaitán, Santiago; Martínez, J.; De Jaeger, Thomas; Hamuy Wackenhut, Mario (IOP Publishing Ltd, 2018)
      We report on the serendipitous observations of solar system objects imaged during the High cadence Transient Survey 2014 observation campaign. Data from this high-cadence wide-field survey was originally analyzed for finding ...
    • Detección de Período en Series de Tiempo Astronómicas Usando Correntropía 

      Huijse Heise, Pablo Andrés (Universidad de ChileCyberDocs, 2010)
      Las series de tiempo estudiadas en astronomía, también conocidas como “Curvas de Luz”, contienen información del brillo estelar versus tiempo y se caracterizan por estar irregularmente muestreadas, poseer múltiples espacios ...
    • Finding periodicities in astronomical light curves using information theoretic learning 

      Huijse Heise, Pablo Andrés (Universidad de Chile, 2014)
      The analysis of time-variable astronomical phenomena is of great interest as it helps to improve our understanding of the structure and topology of our Universe, the mechanisms of galaxy and stellar evolution, etc. The ...
    • A novel, fully automated pipeline for period estimation in the EROS 2 data set 

      Protopapas, Pavlos; Huijse Heise, Pablo Andrés; Estévez Valencia, Pablo; Zegers, Pablo; Principe, José; Marquette, Jean Baptiste (IOP Publishing, 2015)
      We present a new method to discriminate periodic from nonperiodic irregularly sampled light curves. We introduce a periodic kernel and maximize a similarity measure derived from information theory to estimate the periods ...
    • Period Estimation in Astronomical Time Series Using Slotted Correntropy 

      Huijse Heise, Pablo Andrés; Estévez Valencia, Pablo; Zegers, Pablo; Príncipe, José C.; Protopapas, Pavlos (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS, 2011-06)
      In this letter, we propose a method for period estimation in light curves from periodic variable stars using correntropy. Light curves are astronomical time series of stellar brightness over time, and are characterized as ...
    • The high cadence transient survey (HITS). Compilation and characterization of light–curve catalogs 

      Martínez Palomera, Jorge; Forster, Francisco; Protopapas, Pavlos; Maureira, Juan Carlos; Lira Teillery, Paulina; Cabrera Vives, Guillermo; Huijse Heise, Pablo Andrés; Galbany, Lluis; De Jaeger, Thomas; González Gaitán, Santiago; Medina, Gustavo; Pignata Libralato, Giuliano; San Martín Aristegui, Jaime; Hamuy Wackenhut, Mario; Muñoz Vidal, Ricardo Rodrigo (2018)
      The High Cadence Transient Survey (HiTS) aims to discover and study transient objects with characteristic timescales between hours and days, such as pulsating, eclipsing and exploding stars. This survey represents a ...
