    • Gaia DR2 Distances to Planetary Nebulae 

      González Santamaría, I.; Manteiga, Minia; Manchado, Arturo; Ulla, Ana; Dafonte, Carlos (MDPI AG, 2020-04-01)
      [Abstract] The aim of this work is to examine distances to planetary nebulae (PNe) together with other properties that were derived from them, using the astrometry of Gaia Data Release 2 (DR2). We were able to identify ...

    • 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 ...

    • 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 ...

    • Signal Processing Techniques Intended for Peculiar Star Detection in APOGEE Survey 

      Santovena, Raul; Manchado, Arturo; Dafonte, Carlos (M D P I AG, 2019-08-01)
      [Abstract] Like other disciplines, Astronomy faces the era of Big Data, where the analyses and discovery of specific objects is a significant and non-trivial matter. The APOGEE survey and Gaia mission are good examples of ...
