Estudio de las propiedades fisicas en regiones chocadas en nebulosas planetarias 

    Castrillón Camacho, Arjuna (Date of defense: 2021-05-12)

    Planetary nebulae play a very important role in the chemical evolution of galaxies since they are responsible for returning nuclear-processed material to the interstellar medium. Observations of planetary nebulae are used ...

    ISFAA : Implicit SPH for astrophysical apllications 

    Escartín Vigo, José Antonio (Date of defense: 2016-01-21)

    Computational simulation is one of the basic techniques of modern Astrophysics. The long-term time astrophysical processes cannot be treated with explicit approaches because that they are limited, in their maximum time ...

    Latest generation white dwarf cooling models : theory and applications 

    Renedo Rouco, Isabel (Date of defense: 2014-11-13)

    White dwarfs are the most common stellar evolutionary end-point. Moreover, they can be considered as reliable cosmic clocks to infer the age of a wide variety of stellar populations, including globular and open clusters. ...

    Observation and interpretation of type IIB supernova explosions 

    Morales Garoffolo, Antonia (Date of defense: 2016-03-08)

    Core-collapse supernovae (CC-SNe) explosions represent the final demise of massive stars. Among the various types, there is a group of relatively infrequent CC-SNe termed type IIb, which appear to be hybrids between normal ...

    Population synthesis studies of the white dwarfs of the galactic disk and halo 

    Cojocaru, Elena-Ruxandra (Date of defense: 2016-11-24)

    As the evolutionary end-point of most main-sequence stars, white dwarfs can be used to infer important properties concerning the formation and evolution of the different Galactic stellar populations. Population synthesis ...

    Three-dimensional SPH simulations of the interaction between the nova ejecta and the companion star 

    Figueira, Joana (Date of defense: 2023-05-31)

    (English) Classical and Recurrent novae are thermonuclear explosions hosted by accreting white dwarfs in stellar binary systems. Material piles up on top of the white dwarf star under mildly degenerate conditions, driving ...

    White dwarf dynamical interactions 

    Aznar Siguan, Gabriela (Date of defense: 2015-04-30)

    Merging white dwarfs is a promising channel to trigger Type Ia supernovae, known as the double degenerate scenario. Supernovae are stellar explosions that radiate as much energy as any ordinary star is expected to emit ...
