Dynamical formation of long-period exoplanets systems in evolving binary stars
Isabel J. Lima, Rafael R. Sousa, Silvia M. Giuliatti Winter +4
The dynamical formation and evolution of long-period giant exoplanets have not been well constrained due to the few observational parameters. In this study, we explore the dynamica…
Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii
Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56
The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…
The incidence of magnetic cataclysmic variables can be explained by the late appearance of white dwarf magnetic fields
Matthias R. Schreiber, Diogo Belloni
Assuming that white dwarf (WD) magnetic fields are generated by a crystallization- and rotation-driven dynamo, the impact of the late appearance of WD magnetic fields in cataclysmi…
Further evidence of saturated, boosted, and disrupted magnetic braking from evolutionary tracks of cataclysmic variables
Joaquín A. Barraza-Jorquera, Matthias R. Schreiber, Diogo Belloni
Angular momentum loss through magnetic braking drives the spin-down of low-mass stars and the orbital evolution of various close binary systems. Current theories for magnetic braki…
Resolution of a paradox: SDSS J1257+5428 can be explained as a descendant of a cataclysmic variable with an evolved donor
Diogo Belloni, Matthias R. Schreiber, Kareem El-Badry
The existence of the binary system SDSS J1257+5428 has been described as paradoxical. Here we investigate under which conditions SDSS J1257+5428 could be understood as a descendant…
A second candidate magnetic helium core white dwarf and 3 other variable white dwarfs in the globular cluster NGC 6397
Manuel Pichardo Marcano, Liliana E. Rivera Sandoval, Thomas J. Maccarone +5
Using archival Hubble Space Telescope observations, we report the discovery of four variable low-mass white dwarfs () in the globular clu…
