Population synthesis of substellar companions surviving common-envelope evolution
Nicolas F. Miranda, Alex Mauch-Soriano, Joaquin A. Barraza-Jorquera +3
Predicting the population of substellar companions around white dwarfs (WDs) requires accounting for both companions that avoid engulfment during stellar evolution and those that s…
A double debris disc around a white dwarf sculpted by two planetary bodies
Nicola Pietro Gentile Fusillo, Felipe Lagos-Vilches, Boris T. Gänsicke +2
Many planetary systems survive the metamorphosis of their hosts stars into white dwarfs, as demonstrated by the detection of dusty circumstellar discs around these stellar remnants…
The white dwarf binary pathways survey - XI. The Gaia-GALEX UV Excess Sample for systems within 350 pc
James A. Garbutt, S. G. Parsons, N. Gentile Fusillo +9
White dwarfs (WDs) with F, G or K type binary companions are the last common ancestor to a zoo of exotic phenomena. Finding a clean sample of such systems is difficult, as WDs in s…
Direct detections of white dwarfs in four WD+dM post-common envelope binaries within 20 pc
Mairi W. O'Brien, David J. Wilson, Pier-Emmanuel Tremblay +5
Characterising post-common envelope binaries (PCEBs) containing a white dwarf and a main-sequence companion is essential for improving theories of binary evolution. This paper pres…
Predicted incidence of Jupiter-like planets around white dwarfs
Alex Mauch-Soriano, Matthias R. Schreiber, Diego Correa +7
Only a handful of gas giant planets orbiting white dwarfs are known. It remains unclear whether this paucity reflects observational challenges or the consequences of stellar evolut…
Most extremely low mass white dwarfs with non-degenerate companions are inner binaries of hierarchical triples
Felipe Lagos-Vilches, Mercedes Hernandez, Matthias R. Schreiber +2
Extremely-low-mass white dwarfs (ELM WDs) with non-degenerate companions are believed to originate from solar-type main-sequence binaries undergoing stable Roche lobe overflow mass…
