Synthetic X-ray emission from white dwarf accreting planetary material
S. Estrada-Dorado, V. Lora, J. A. Toalá +4
The emission of hard X-rays associated with white dwarfs (WD) can be generated by the presence of a stellar companion either by the companion's coronal emission or by an accretion…
Disentangling the parameter space: The role of planet multiplicity in triggering dynamical instabilities on planetary systems around white dwarfs
R. F. Maldonado, E. Villaver, A. J. Mustill +1
Planets orbiting intermediate and low-mass stars are in jeopardy as their stellar hosts evolve to white dwarfs (WDs) because the dynamics of the planetary system changes due to the…
Do instabilities in high-multiplicity systems explain the existence of close-in white dwarf planets?
R. F. Maldonado, E. Villaver, A. J. Mustill +2
We investigate the origin of close-in planets and related phenomena orbiting white dwarfs (WDs), which are thought to originate from orbits more distant from the star. We use the p…
Understanding the origin of white dwarf atmospheric pollution by dynamical simulations based on detected three-planet systems
R. F. Maldonado, E. Villaver, A. J. Mustill +2
Between 25-50 % of white dwarfs (WD) present atmospheric pollution by metals, mainly by rocky material, which has been detected as gas/dust discs, or in the form of photometric tra…
Dynamical evolution of two-planet systems and its connection with white dwarf atmospheric pollution
R. F. Maldonado, E. Villaver, A. J. Mustill +2
Asteroid material is detected in white dwarfs (WDs) as atmospheric pollution by metals, in the form of gas/dust discs, or in photometric transits. Within the current paradigm, mino…
Infrared excesses in stars with and without planets using revised photometry
Raul F. Maldonado, Miguel Chavez, Emanuele Bertone +1
We present an analysis on the potential prevalence of mid infrared excesses in stars with and without planetary companions. Based on an extended database of stars detected with the…
