    • Population synthesis study of the Gaia white dwarf population 

      Ferrer i Burjachs, Aina (Universitat Politècnica de Catalunya, 2021-07-13)
      Treball Final de Grau
      Accés obert
      We conduct a population synthesis study of the white dwarf population within 100pc from the Sun. Such simulations are based on a detailed Monte Carlo code, which provides synthetic samples of both single and binary stars ...

    • Random forest identification of Gaia white dwarf-main sequence binary spectra 

      Chavanel I Saltó, Adrià (Universitat Politècnica de Catalunya, 2023-07-11)
      Treball Final de Grau
      Accés obert
      Recent space missions such as the ESA Gaia satellite have provided an unprecedented wealth of astronomical information for billions of stars in our Galaxy. In particular, the third data release of Gaia has provided spectra ...

    • Reconstructing binary system histories through inverse population synthesis techniques 

      Gili Esteva, Marta (Universitat Politècnica de Catalunya, 2023-06-26)
      Treball Final de Grau
      Accés obert
      Population synthesis studies are a powerful tool for modeling large samples of a wide variety of stellar objects. From an observational point of view, individual systems sometimes require specific analysis in order to ...

    • Spectral automated classification in large databases 

      Echeverry Valencia, Cristian David (Universitat Politècnica de Catalunya, 2021-07-15)
      Treball Final de Grau
      Accés obert
      Due to the vast amount of data collected every day, there exists a need of modelling Machine Learning algorithms that are able to manipulate and link the raw data with as little human supervision as possible. One of the ...

    • Spectroscopic follow-up of Gaia-selected white dwarfs 

      Diaz Sancho, Aleix (Universitat Politècnica de Catalunya, 2023-06-27)
      Treball Final de Grau
      Accés obert
      Realitzat a/amb:   European Southern Observatory
      Astronomy unveils the wonders of the universe, including white dwarfs. These stellar remnants, with their dense cores, offer insights into stellar evolution and the cosmos. Spectroscopy, a powerful tool in astronomy, plays ...

    • Spectroscopy of nearby white dwarfs & identification of double white dwarfs in common proper motion pairs 

      Perpinyà Vallés, Martí (Universitat Politècnica de Catalunya, 2018-07)
      Treball Final de Grau
      Accés obert
      Realitzat a/amb:   University of Warwick
      On the one hand, this project presents a background in both White Dwarfs and spectroscopy. Some data from Warwick University Astrophysics? Group has been studied and these spectroscopic results are introduced in order to ...
