    • GUASOM: An Adaptive Visualization Tool for Unsupervised Clustering in Spectrophotometric Astronomical Surveys 

      Álvarez, M. A.; Dafonte, Carlos; Manteiga, Minia; Garabato, D.; Santoveña, Raúl (Springer, 2022)
      [Abstract] We present an adaptive visualization tool for unsupervised classification of astronomical objects in a Big Data context such as the one found in the increasingly popular large spectrophotometric sky surveys. ...

    • Mining of the Milky Way Star Archive Gaia-DR2: Searching for Binary Stars in Planetary Nebulae 

      González Santamaría, I.; Manteiga, Minia; Dafonte, Carlos; Manchado, Arturo; Ulla, Ana (MDPI AG, 2020-08-31)
      [Abstract] The aim of this work is to search for binary stars associated to planetary nebulae (ionized stellar envelopes in expansion), by mining the astronomical archive of Gaia DR2, that is composed by around 1.7 billion ...

    • On the estimation of stellar parameters with uncertainty prediction from Generative Artificial Neural Networks: application to Gaia RVS simulated spectra 

      Dafonte, Carlos; Fustes, D.; Manteiga, Minia; Garabato, D.; Álvarez, M. A.; Ulla, A.; Allende-Prieto, Carlos (EDP Sciences, 2016-10)
      [Abstract]: Aims. We present an innovative artificial neural network (ANN) architecture, called Generative ANN (GANN), that computes the forward model, that is it learns the function that relates the unknown outputs (stellar ...

    • Phosphorus-Rich Stars With Unusual Abundances Are Challenging Theoretical Predictions 

      Masseron, Thomas; García-Hernández, D. A.; Santoveña, Raúl; Manchado, Arturo; Zamora, Olga; Manteiga, Minia; Dafonte, Carlos (Nature Publishing Group, 2020-08-04)
      [Abstract] Almost all chemical elements have been made by nucleosynthetic reactions in various kind of stars and have been accumulated along our cosmic history. Among those elements, the origin of phosphorus is of extreme ...

    • Planetary Nebulae in Gaia EDR3: Central Star Identification, Properties, and Binarity 

      González Santamaría, I.; Manteiga, Minia; Manchado, Arturo; Ulla, Ana; Dafonte, Carlos; López-Varela, Pablo (EDP Science, 2021)
      [Abstract] Context. The Gaia Early Data Release 3 (EDR3), published in December 2020, features improved photometry and astrometry compared to that published in the previous DR2 file and includes a substantially larger ...

    • The Gaia mission 

      Prusti, T.; Manteiga, Minia; Álvarez, M. A.; Arcay, Bernardino; Dafonte, Carlos; Garabato, D.; Fustes, D.; Liu, C.; Bruijne, J. H. J. de; Brown, A. G. A. (EDP Sciences, 2016-11)
      [Abstract]: Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was ...
