Implications of the interstellar object 1I/'Oumuamua for planetary dynamics and planetesimal formation
Sean N. Raymond, Philip J. Armitage, Dimitri Veras +2
'Oumuamua, the first bona-fide interstellar planetesimal, was discovered passing through our Solar System on a hyperbolic orbit. This object was likely dynamically ejected from an…
Unstable low-mass planetary systems as drivers of white dwarf pollution
Alexander J Mustill, Eva Villaver, Dimitri Veras +2
At least 25% of white dwarfs show atmospheric pollution by metals, sometimes accompanied by detectable circumstellar dust/gas discs or (in the case of WD 1145+017) transiting disin…
The critical binary star separation for a planetary system origin of white dwarf pollution
Dimitri Veras, Siyi Xu, Alberto Rebassa-Mansergas
The atmospheres of between one quarter and one half of observed single white dwarfs in the Milky Way contain heavy element pollution from planetary debris. The pollution observed i…
Weighing in on the masses of retired A stars with asteroseismology: K2 observations of the exoplanet-host star HD 212771
Tiago L. Campante, Dimitri Veras, Thomas S. H. North +12
Doppler-based planet surveys point to an increasing occurrence rate of giant planets with stellar mass. Such surveys rely on evolved stars for a sample of intermediate-mass stars (…
Eclipse, transit and occultation geometry of planetary systems at exo-syzygy
Dimitri Veras, Elme Breedt
Although conjunctions and oppositions frequently occur in planetary systems, eclipse-related phenomena are usually described from an Earth-centric perspective. Space missions to di…
Deposition of steeply infalling debris around white dwarf stars
John C. Brown, Dimitri Veras, Boris T. Gaensicke
High-metallicity pollution is common in white dwarf (WD) stars hosting remnant planetary systems. However, they rarely have detectable debris accretion discs, possibly because much…
